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.
Hi all,
I've seen multiple cases where Desire starts to show every appointment in double, even though there is only one appointment on outlook side. We are syncing directly to Exchange 2003, so no google mail or direct pc sync.
Problem comes randomly and is fixed by deleting exchange account, deleting cache from Calendar + Calendar storage and then adding exchange account back.
Any idea what could be the cause of this problem?
Also problems with recurring calendar entries
I have a monthly recurring event in my Outlook agenda, every 4th working day of the month I get a reminder to do some administration.
After using Exchange ActiveSync (I only sync over the air), I get this entry on a daily basis. I already deleted and recreated it on the PC and it was only correct after the first sync. After that, I have the daily entry again.
I really like the phone, but MS does a better job in some specific areas (mostly for the business users).
Update my HOX to 4.1.1 two weeks ago. Found out one strange issue related to Exchange Activesync Calendar
If setup an all day event of D day (one PC with Outlook or on HOX), Although the event will show up correctly in the stock Calendar App (at the top column of day view, as 1st attached picture), but if you tap it and enter the detail view, the event will show up as from D day 0:00 to D+1 day 0:00. <--as "Test Exchange in attached picture"
Setup a All day event in Google Calendar will have no this problem. When tap and enter the detail view of event, it will still show as "All Day" (as "Test Google" in attached picture", instead of "D day 0:00 to D+1 day 0:00"
This problem will make Calendar related APPs behave strangely. Like Smooth Calendar will show this "All Day" event whole day, even it was setup to hide the "All day" from SC's view.
Anyone has same issue or a solution?
It's confirmed that it's not happened before upgrade to 4.1.1, my other phone (Desire) with Gingerbread has no this problem when sync to same Exchange server, neither.
Thanks!
262 views and still no reply? Anyone confirmed this problem?
Probably just the way the two companies handle their calendars.
Outlook may be based on time.
Whereas Google may look at them as days, unless a time is stated.

Thanks for the reply. However, before update to 41.1, everything is okay... All day event is represented same for both Exchange and Google...
Since it's broken through the system (different calendar app shows same result), I suspect it's in the underlying Activesync code in 4.1.1, not just the problem of Calendar app.

Same problem here. All day events in Exchange calendar show up from 11:00 pm actual day til 11:00 pm next day. No solution found yet.
With Google calendar everything is okay.

Is there any update on this? I've got exactly the same problem with some all day entries (typically birthdays or anniversaries) appearing as starting at 23:00 on the correct day and running until 23:00 on the following day. Phone was updated to JB a few months ago and I only added the Active sync account on Monday. It is definitely an Android based problem as other devices (iPad, BlackBerry) work fine.
Waiting in antici.................................pation of an update.
I have the same issue with HTC One and Asus Infiniti tab The only thing that seems to help for now is to open every such recurring all-day event in Outlook, open the series properties, change the event hours from 00:00-00:00 to 00:00-23:59 (duration 2879 mins), save it. Wait for the phone to sync, open the event in Outlook once again and change the event hours back from 00:00-23:59 to 00:00-00:00 (duration 1 day). Wait for the phone to sync, everything is OK then. Little tiresome workaround, but at least it works. What is interesting it is definitely Android issue, because all my devices with Android 4.1+ have the same issue. I think it is somehow related to time zone issues. The other trick is to remove problematic event and create it directly from the phone's calendar app.
