Since I have a TP2 I figure I will post this issue in here..
Recently I installed iCalParse and loaded some iCal files from Google Calendar. Afterward all my calendar events on my phone and on my Outlook Exchange were gone. Well that stinks, but I went through and added them back and got rid of iCalParse (just load the ical files via Outlook instead).
The really pain is that now my Exchange Activesync will not automatically retrieve e-mail or calendar events. I have tried to set it to a timer and also "As items arrive", which is what I had been using. I can manually sync (via Send/Receive or Sync), but the auto sync won't run.
Is there a service that should be running that may have been corrupted? Anyone else seen this issue before?
I've had my 2 Desires for about 3 weeks now. When I first received them we were using MS Exchange 2003, and Mail/Contacts/Calendar all synced perfectly.
Since then, we have upgraded our Exchange Server to Exchange 2010, which is lovely, BUT it turns out that the Desire Calendar will not sync with Exchange 2010. It would seem to be a Desire/HTC issue, as our iPhones/iPod Touches still sync Calendar fine with Exchange 2010.
I also note that a colleague is syncing the Desire Calendar with Exchange 2007 without problems.
So it is the combination of Desire Calendar and Exchange 2010 which fails. If I go to Settings/Accounts & Sync/Exchange Activesync and enable Calendar Sync I can see error messages saying "Syncronization is experiencing problems". If I leave Calenday sync enabled, it causes Mail and Contacts to sync poorly too, but if I disable Calendar sync, Mail and Contacts sync fine.
Has anyone else got Calendar sync working with Exchange 2010?
Desire Exchange 2010 Calendar
I recieved my Desire yesterday after reading quite a bit about it. Yes it can Sync with Exchange and all is what i read.
I set it up to Sync with the Exchange 2010 server and to my surprise it didn't sync the existing calendar items. Contacts and Mail is no problem.
If i add e new Calendar item on the Desire it does show in Outlook on my pc so Exchange does have a sort of sync with the Calendar. Adding a new item in Outlook never shows on the Desire. It seems like a one way sync or something. The Desire can sync to Exchange but it seems Exchange cannot sync to the Desire
I have a test account on one of our clients Managed Exchange 2007 servers. Setting up ActiveSync to the Exchange 2007 server works like a charm. Full sync both ways.
Just modify all your calendar items, for example by adding an additonal category by change your view to "list" or "list all active" and selecting all your appointments. Add a category, remove the category and switch back your view. Now you can happy sync your calendar with E2k10
Whoa! Steady there.
Can you give me some background to this before I apply it to my 12 year calendar history? How did you discover this, and have you actually successfully done this?
It worked and now not anymore
Strangest thing. My girlfriend planned a few appointments in here Calendar and invited me. So I accepted those invites on my Desire and all of a sudden the 2way sync worked. I could add items on my Desire and they popped up in the Exchange/Outlook Calendar and vice versa.
But that was unitil I rooted my device this morning...meaning new flash and standard factory reset. Now it will not sync the Calendar anymore. Tried sending new invites from a different account without any luck.
So...the calendar sync does work eventually...dont know why or how I did it.
Other thing you could do is, is install HTC Sync and manually do an Outlook sync of only the Calendar items (all items). I did this and they all showed up on my Desire. I did a one time sync.
Trying to figure out how to get the sync working again.

Not really any background information, sorry. I've done some research on it but did not find anything, including analysing the extended sync protocols, everything looks ok, but there's no sync.
I've got this solution from a swiss-forum "android.pocketpc.ch" (sorry I can't post links since no moderator removed the restrictions yet) and it worked like a charm. I've tried it since I'm the Exchange-Admin myself and I now I've a functional backup;-)
Same problem here. Cannot get calendar to Sync with Exchange 2010.
If I add a new meeting to the Desire it appears in Outlook.
If I modify this meeting in Outlook then it appears as 2 separate meetings on the Desire.
If I delete an appointment on the Desire then it comes back once the sync runs.
All in all very disappointing for a State of the art phone.
Anyone got a real fix for the Exchange 2010 calendar problem?
A huge thanks to dab_ch for posting above the workaround to get the Calendar syncing to Exchange 2010. This is now working perfect to two Desires here.
If you have this problem, follow the advice in the post above. It worked for me, twice.
dab_ch fix is only working in part for me.
Some of the Exchange calendar items still do not appear on the Phone.
If I modify an appointment on Exchange the change is not reflected on the next sync from Exchange
Also, While Exchange Contacts are appearing on the phone. If I add a new contact to the Phone this does not appear in exchange.
The Sync Process still reports "Synchronization is experiencing problems."
A Further update.
I setup a new account on Exchange2010 and then transferred the Calendar using export and import.
Now my Calendar Synch in both directions is working fine.
It looks like my problem was related to a problem with my account on Exchange or some appointment in it.
Contact Sync problems
While the calendar is working 100%.
I still have a problem, that if I create a contact on the phone it does not sync to Exchange 2010.
There are no errors from the ActiveSync process.
Is anybody else having this issue?
Please note that if your Desktop Outlook client is using 'Cached Mailbox', then after adding the temporary category to each item, you MUST wait for the local Outlook database to sync completely back to the Exchange before you then remove the temporary category and then again wait for the completion of the sync back to exchange from Outlook.
Failure to comply with this will leave you with only a partially synced database - the part which did manage to sync back to Exchange.
You can tell when it is still syncing by watching the satus bar at the bottom of Outlook - it will say 'Updating Calendar', then after a few minutes return to 'All folders are up to date'.
Note the sync doesnt start immediately, so you wil see the 'All folders are up to date' message for perhaps 15 seconds before the sync starts. Wait for the 'Updating...' message etc.
Contact sync does seem slow, but it does work here eventually. It ought to be fast tho, so something is not right. I even tried the temporary category trick, but it didnt speed it up.
XDAgeek you are right.
I tried a number of different accounts to reproduce the problem with the Calendar and it seems Cache mode was my issue.
The Calendar sync is now working 100%.
On the Contact Sync from Phone issue, this still seems to be not working. I added a contact to one of my test Desire phones two days ago and it is still not in exchange.
For me it was not the cache mode.
I did an export-mailbox on the Exchange 2010 server.
Deleted my mailbox...recreated it so it was blank....no synch issue of course (So it is definitely not an Exchange 2010 issue)
I created 1 item in the Calendar in Outlook 2007 and that popped up nicely on the Desire. Great...so I thought.
Did an import-mailbox with the backed up pst...and Sync had problems again.
Started filtering out where the problem came from.
Turns out I had some Items (birthdays and such) with recurrence that the ActiveSync in Android is not happy about (Same Items sync fine with a WinMo 6.1 device). So I deleted all the recurrence itmes and copying them back 1 by 1. Syncing was still going fine until a certain item. So I edited that item by removing the recurrence pattern and reapplying it making sure it was an All Day event (that is a Birthday usually ). And Presto...everthing is syncing fine now.
Better logging is needed?

Mine is working fine syncing calendar with Exchange 2010, has been since i got my desire back in March.
Very strange that so many people are having the same issue.
after a few beers
sorry this post is under the influence but...
there is a subtle problem with my synching. overall the calender syncs fine. with one exception: any diary entry i type directly into outlook, (with receipients also), does not synch. if i am sent and then accept an entry, or if i make the entry on my phone it syncs. direct outlook entry does not work. pants.

I have exactly the same problem. If a collegue invites me, my calendar syncs fine, but if I add items myself, the sync is almost random (some items dissappear) and the new item does not show/sync.
I really do not want to delete all recurring items, but maybe i'll give it a try. Google Calendar Sync does not seem to be a great solution either.
HTC answered me (i have a Legend) that Exchange 2010 is currently NOT supported.
Thanks all, I follow the "category" method and it works like charm now!!! )))
Category.. No category... SYNC!
Thanks!
Also for me the assign category then undo worked.
Now my whole calendar is synced and I'm ready to go!
skip to the end for the solution!
Our IS department helpfully upgraded our exchange server overnight to exchange 2010.
After putting in the new details we hit a problem - the calender refused to sync and just came back with the unhelpful "an error has occurred"
We did a bit of googling and realised that quite a few other people were having the same problem with 2010. Most had placed the fault with HTC or Android - we were able to do a bit of digging and certainly with our problems we found a solution.
We tried to sync with another account on our phones (2 different Desires one orange branded one "normal") another test account synced fine - no errors. So that narrowed the fault down to our specific exchange accounts. A bit more googling suggested that possibly corrupted entry's in the calender were causing the sync to fail - or open ended repeating appointments (such as birthdays)
Our IS department found 1 corrupted entry in my colleagues account (a meeting that appeared to be set for some time 3072 ....) I deleted all of my repeating birthdays (they were all in my Google cal anyway). Once this was done both accounts started to sync with no problems.
So the short version - if you cant sync with exchange 2010 on your HTC Desire - find and remove those corrupted entry's and/or delete/edit open ended repeating appointments.
Hopefully this will be useful to someone who will be able to avoid the same couple of hours of panic that we had this morning!
Argh. I cannot tell my users to delete all their open-ended recurring appointments when we migrate to Exchange 2010 later this year...
We also had this problem with exchange 2010 and a number of Desire's and have resolved it by following the advise on/showthread.php?p=6305877#post6305877"]http://forum.xda-developers.com/showthread.php?p=6305877#post6305877[/URL]
When we selected all appointments, assigned a category, then selectd all appointments again and removed the category. waited 10 minutes to ensure Outlook cache and Exchange has synced.
After this the phones worked fine.

the open ended thing maybe not the solution - it may be that one of the recurring appointments was corrupted - could have just been coincidence
the category solution sounds much better !!
alternative for low number of users of exchange
sync emails and contacts normally, download htc sync to computer for calendar. Not Ideal but it works from exchange to the phone but not from the phone to exchange
I want to bump up this thread, as a form of thanks to TS, because after hours of troubleshooting (on why my calendar doesn't get sync), and numerous factory reset, I found out that it's indeed some corrupted entry in the calendar that causes the calendar not being able to sync!
Thanks ever so much!
This solution worked for me on a HTC Wildfire with Android 2.2
As advised, I went into my Desktop Outlook calender, and either deleted or "Saved & Closed" all recurring appointments. Used the month view for this. Works like a charm now! Thank you once again
i never had problem syncing with exchange 2010
Guys,
I had the same issue where the calendar wasn't syncing. The fix that I found was that I had some recurring appointments in outlook with no end date. I put an end date on these in outlook, let it sync back to the server and then the calendar synced first time.
Hi
I have seven calendars being synced and displayed together on my phone calendar application (HTC Desire Android 2.2 stock). One calendar containing my University schedules is suddenly toast, meaning that all regularly occuring events won't be visible anymore on my phone.
On calendar.google.com, as well as on my other calendar clients Windows Live Mail and Outlook 2010, my calendar seems perfectly fine. The calendar I'm talking about is linked to my primary Gmail Account, as are three other calendars. What did I do, and what can I do to fix this?
Single events are still visible...
Thank you in advance.
It just happened again! I lost all my recurring events on one of my calendars; my phone won't display them anymore. On calendar.google.com everything is still visible. Just like in my mail client.
Why does this keep happening to me?
Solution: I just found a quick workaround. In the HTC calendar app, just remove the calendar, then wait for synchronization. After that, add it again and synchronize again. Everything's displayed. I guess it might be a software bug.
I am getting duplicate entries in the calendar from my exchange accounts. Is this a known problem and is there a fix?
I have tried deleting the calendar storage and removing then re adding the accounts.
thanks
I have the same issue ... I thought it was because I switched time zones but can't confirm that.

I had that problem once before on my old epic. If I remember correctly it was because I had 2 accounts synced to my phone, Google and Yahoo? Now I just sync everything to Google only. I was also getting duplicated in contacts.

I think it is a problem with the S3 calendar app or the exchange sync. I have synced the same accounts on other android phones and have not had any issues with duplicate calendar entries. I sync my work exchange account and a hotmail account. This gives me my work and personal calendars. I only sync contacts from my hotmail account. I do not want to use google since I already have everything setup on my other accounts.
I will try doing some reconfiguring of the accounts tonight. I will post an update if I find anything interesting.
Re-Duplicate Calendar/Contacts entries from Exchange Server
Last week my S3 started duplicating both calendar and contact entries. This only occurs on my Exchange work email. I can clear out my contact and calendar storage and then resynch and it will be fine for a few hours. Then i will get duplicate entries. I did not reset my storage after seeing the duplicates today and now a third set of the same entries are showing up. Very frustrating. I have uninstalled the apps I've loaded in the last week.
I was rooted and had not downloaded any upgrades when this started. Yesterday I went back to the stock rom thinking that was the problem. It is still happening after I reset to stock ROM and downloaded the available upgrades.
This is very frustrating and it is odd that this started recently. Maybe something changed with corporate exchange servers in the last couple of weeks that caused this conflict.
Looking forward to a resolution.
I have the same problem. Now I have 8 times every contact and calendar entry. When I delete the account is working for some hours and then start dublicating as well. I have 2 exchange accounts, my corporate that I sync everything and my hotmail that sync only email.
I now only have one exchange calendar syncing and I am still getting duplicates. I have tried to reproduce the duplication by restarting and re-syncing but neither one created duplicates manually. Next I am going to remove all of my accounts, delete all the calendar & contact storage then add back one account. I will run wiht only the one account for a day to see what happens
Solution (At least working for a day now)
I was getting duplicates every few hours and now I am 1 full day without. Here is what I did:
1. I deleted all of my Exchange ActiveSync type accounts. I had three mail accounts using the exchange option : Corporate, Gmail and Hotmail
2. Went to Task Manager and View All processes and Find the Calendar and Contact storage apps and cleared the data.
3. Setup my Corporate account using Exchange ActiveSync
4. Setup synch for Gmail using the Google Account
5. Setup Hotmail with the Hotmail app.
(Dont like Gmail and Hotmail separated, because I enjoyed having all emails in a combined view)
Doesnt seem to make sense, why this has started happening in the last couple of weeks, because I had this setup since I setup the phone the end of June.

I'm going to try this method and see if it works out. I too, had 2 Exchange ActiveSync email accounts associated with my stock email client (Corporate and Hotmail) But I'm going to try and set up the Hotmail account as a POP3 this time and see if that alleviates the multiple calendar entry catastrophe!
I made some progress in my testing. Here is what I did.
First test
1. Removed all accounts using the default email client.
2. Cleared all data for calendar and contacts
3. Restarted phone
4. Only setup one account using exchange and synced mail, calendar and contacts using default email client
5. No duplicates after 3 days.
Second test
1. Removed all accounts using the default email client.
2. Cleared all data for calendar and contacts
3. Restarted phone
4. Setup two account using exchange and synced mail, calendar and contacts using default email client
5. After the first day I started getting duplicates in the calendar and contacts.
Third test
1. Removed all accounts using the default email client.
2. Cleared all data for calendar and contacts
3. Restarted phone
4. Setup one account using exchange and synced mail and calendar using default email
5. Setup one account using exchange and synced mail, calendar and contacts using Enhanced Email
6. After the first day I started getting duplicates in the calendar and contacts.
Fourth Test
1. Removed all accounts using the default email client.
2. Cleared all data for calendar and contacts
3. Restarted phone
4. Setup up my Office Exchange (Sync mail & calendar), Hotmail (Sync mail, contacts, & calendar), and Live (Sync mail) accounts. All accounts are setup as exchange accounts using Enhanced Email.
5. Now after two days there are no duplicates in either the calendar or contacts.
I dont if Enhanced Email syncs differently than the default email client. I believe that there is a problem with the default email syncing process. I never had this problem with my Gingerbread phones.
duplicate appointments and contacts
The duplicating calendar and contacts problem was driving me crazy as well. It just seemed to keep getting worse with more and more duplicates as time went by.
I could remove the duplicates by removing my Exchange account and then re-adding it back in, but the duplicates would show up again hours later.
I removed/added my exchange account a bunch of times, and each time the duplicates came back... except this last time.
The only thing I did different this last time (that I know of) was goto: Settings, then Backup and Reset, and uncheck "Back up my data". Then I removed/added Exchange.
Since doing this, I have had no more duplicating appointments or contacts. It has been several days, maybe a week now.

I will try that and see what happens over a few days.
Workaround: Google Calendar sync option
I had the same issue on my Galaxy S2 Skyrocket. I removed my Exchange Server account -> Synced calendar -> Made sure the Exchange entries were gone from Calendar -> Install Google Calendar Sync in your PC that has the exchange server and do the 1-way sync option from Exchange to Google -> Resync Google Calendar on phone -> Add Exchange Server account on phone.
This is a roundabout method to remove duplicate entries but it works great for me and should do so for you as well. There is a one-time setup of Google Calendar sync on your PC and that's about it.

Can you please point me to the difference in setting up via default email client vs setting it up using Enhanced Email?
My Father-in-law has his gmail account and a Microsoft Exchange ActiveSync account (for work) syncing on his GS3 and is getting duplicate events from the Microsoft Exchange ActiveSync account. I'm trying to help him remove those duplicate entries. Apparently his IT guy at work setup the ActiveSync account and he didn't know how to set it up, so I couldn't remove and add it back.
I'm just not sure how I should tell him to set it up differently this time. Note: I saw the item to remove the check mark for backing up items. Did that work for you as well?
Solution I found that works for my HTC Android
opened my Droid's Calendar,
then touched Menu button,
then "More",
then unchecked the box next to Calendar,
and checked only the calendar I want to sync and show (Exchange)
waited for everything to clear itself out.
done / fixed.
Why I don't have Exchange on my droid?! I have the same problem: duplicate calendar entries. I simply use S2 (Jelly bean) and my default gmail account and its calendar! nothing more. but there are many duplicates. I can't see exchange in my calendar list
