Exchange 2010 Sync Calendar Problem (solution!)

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.

Google Calendar sync more than one year

Does anyone know how to get google calendars to sync events 1 year plus? currently only recurring events sync past 1 year, but not individual events

You are lucky. I have only 6 weeks back.
How did you enable 1 year?

Mine has always sync'd +/- one year... no settings seem to be available to change this, so not sure why you have less... I need two years!

I have this issue too... have calendar events going back 2-3 years, and recently I can only sync 6 weeks on my Desire. Google Calendar shows all my events going back to 2009.

Hi all,
Found a method that did the trick for me.
Turn Auto and background sync off.
Delete data for Calendar and Calendar Storage.
Change date to something like 1 Jan 2009.
Turn sync back on.
After a few minutes it will resycn all calendar data.
Change date back to auto

With a custom app you can sync in any range .... I use "Business Calendar". Definitely better than the stock app !

Wow -- I'm shocked that there's no way to change the synced date range within Google's app.

I would use something else, but I like the HTC Sense Calendar app.
Will take a look at "Business Calendar" though.

How do you do that? The BC forum suggests using something like Synthesis syncML, and I've tried that, but I don't understand how to configure it.

I tried that business calendar but found if you store contacts birthdays then close app then open again it has deleted info not sure why because if you store it as pc sync they are ok.

Problems with Exchange Sync and Recurring Meetings

Gang,
Full disclosure - I've lurked here for the past few months, but have only just been stirred to register to try and resolve this issue. I'm thinking that if anyone can help me resolve this, it's you guys. That said, I hope to be able to contribute some myself going forward.
OK, now that I've got that out of the way...
Recently, I've been having problems with recurring meetings from Exchange on my Incredible's ActiveSync calendar. Specifically, the problems seem to start whenever I modify one instance of a recurrence (move one to another day, for example) inside Outlook on my PC - (not on the phone). What seems to be happening is that although that particular changed instance shows up on my HTC calendar in its new spot, the rest of the recurrence disappears and - even worse - I can no longer get ANY recurring meetings to sync to the phone, even if I create new ones.
If I remove the ActiveSync account, delete Calendar Data (Settings > Applications > Manage Applications > Calendar Storage > Clear Data and ...Calendar > Clear Data) and re-add the account, I still have the problem and - what's worse - ALL my recurring meetings are gone (but any exceptions to them remain - WTF?!).
Before anyone asks, all recurrences have end dates (I've read plenty about recurrences w/o end dates causing problems).
To date, the only way I've found to completely fix this is to do a factory reset (yuck). Of course, the minute I modify an instance of a recurring meeting, the problem starts all over.
Anybody else see this? Provided there's no fix, is there a better way to fully flush calendar data to see if I can avoid resetting the phone? There's GOT to be something I'm missing in terms of cleaning out the calendar data, because a factory reset fixes it. Like I said above, I clear out two spots in Manage Applications: Calendar and Calendar Storage.
It's killing me. I'm clearly not doing enough by clearing data for Calendar and Calendar Storage, but I'm thinking a factory reset HAS to be overkill. Anybody know how to more fully flush the calendar data?
Thanks in advance to anyone with ideas. I'm pulling my hair out over here.

I've had this problem as well, except with Google Calendar as I personally don't use Exchange.
Clearing Calendar and Calendar Storage fixes my problem, but I think the issue is that HTC had to bridge the gap left by Eclair to sync with Exchange servers. So, my thought is to perhaps try clearing the Sync Service or Sync Feeds (tired brain has trouble with memory recall) in addition to Calendar and Calendar Storage.
Good news is reports indicate that the FroYo update contains a fix baked in by HTC.
Hope that was in any way helpful.

Thanks for the advice. Tried it, but to no avail.
That said, I'm an avid Tasker user and happened across a new thread in the Tasker Google Group that sounded awfully familiar. Did some troubleshooting and was able to prove that if I have a profile that monitors my calendar (whether this profile is enabled OR disabled), the recurring meeting problem crops up. Sucks, because I really liked my "Don't be a Jerk!" profile that automatically put my phone on vibrate when I had a meeting with "1:1" in the title.
Go figure!

That is interesting to learn! I'm a fellow Tasker and couldn't live without the program.
Hmm... I wonder if a usb sync via HTC Sync and Outlook would be a temporary fix to "reset" your calendar when it goes haywire? It's rather left field, but worth a shot.

I have the same issue and not only with recurring appointments. sometimes the reminder doesn't show up -and sound- even if it's not a recurring appointment.
the funny think is that it happens only with the appointents that I created... it's becoming really frustrating.
I never connect my phone to my PC to synch it

Known issue. Reported and confirmed by HTC along time ago. They "hope" to have it corrected in new release. Work with all recurring events from outlook or OWA, don't attempt to alter, move or do anything to them from the INC.
If you use Google connector and sync to google you are OK, but pretty lame for a phone that was suppose to be exchange compatible. HTC said it's due to the "Sense" interface and the way it connects to the phone's database.

So HTC has confirmed there's an issue when you modify appointments from the phone? Not a big issue for me, because all I ever do is accept others' invitations and MAYBE set up a quick meeting here and there. All my calendar work is in Outlook directly. Thanks for the heads-up, though. Seems silly that a UI layer would introduce issues in database connectivity. Sounds like some of the projects that go on at work - LOL.

Wow, I just now realized that I have a similar problem: ANY recurring appointment disappears from my calendar. Regardless of how I make it recurring (on the phone, on my PC, OWA, etc.) This is positively infuriating.

I actually have the recurring meetings on my phone; however the reminder is gone and the phone is not reminding me that is very annoying. for corporate users this is an awful limitation.
I'm trying to manually add the reminder to the appointment (on the phone) and see if it helps.

I tried creating the recurring appointments on the phone, which is a pain and you have extremely limited options for recurrences. The second I saved the appointement, it disappeared from my phone, but appeared on my exchange calendar online... I'm thinking about attempting to just export my recurrences from exchange to my google calendar...

Clearing those two items worked for me!

I setup all my appointments with my laptop; using the phone just screws it up. then the meetings appear on the phone without reminder.
MLT2004 confirmed it's a known issue.
for me it's mainly an issue with the reminder (VERY annoying for me since I rely on it a lot) but should I need to setup meetings on the phone I would be in trouble.

I always thought it was and activsync problem. I had this problem for 2 years with my Moto Q. Haven't had my Incredible long enough to see if this one is doing it too. Then again since I don't have to use Activesync with this phone I don't. Maybe it's the Activesync that's causing all this.

So now I seem to have a new problem, and I don't mean to hijack the thread (i'll happily start a new one if the OP prefers, but I suspect taht these issues aer related): All of my exchange appointments show up perfectly in my calendar. Even my recurring appointments. The problem is, my exchange calendar is not showing up, ie, the phone seems to realize that these appointments exist, but does not seem to "see" the exchange calendar. If I open an exchange appointment, I can see that it is, in fact, in my exchange calendar. However, if i go to "more" under calendar, I can see my gmail calendar, "My Calendar," "PC Sync," and "US Holidays." If I uncheck them ALL, my exchange appointments remain, but again, I cannot "see" the calendar, to add appointments, etc.

[Q] Problem with appointment time when sync with exchange

When I create a new meeting in my pc thourgh Outlook, the time of the appointment in the HTC is one hour before the right time (for example 15:00 instead of 16:00).
When I create a new meeting on the HTC - there is no problem, and the accurate time is seen in my PC Outlook.
(same problem appears in the calendar app which comes with the HTC as well as with TouchDown app which I prefer to use)
I've verfied that the exchange server, my pc and the phone - are all in the same time zone (GMT+2)
I've tried to uncheck the "automatic use of network provided values" in Setting/Date & Time, but it makes no difference.
The exchange server version is 2003.
Any ideas how to solve this problem?
Thanks,
Gal

I detected a bug when you create on outlook a meeting each last working day of the month (for ex remember to send your timesheet), the phone works for the first meeting and then repeat it every day

next appointment only works on default calendar
With my business we have multiple calendars. The calendar for this a calendar for that calendar for the other. But they are all synced onto my android so I can see every different type of calendar. The problem is Google now only shows the next calendar event for the calendar events that I created on my default calendar not the other ones that i sync. That means I miss a lot of meetings. It wouldn't be that bad if I could copy an event that I'm synced to to my main default calendar. But there's no way to do that an android.

Enter only your city for location, no address, apartment, etc. It will work.
If anyone has a better fix, let us know.

This is clearly a bug in the Android version of Google Now. Using the same google account next appointment cards show up fine on my ipad but the android version never shows them no matter what I do. Bit weird that it doesn't work properly on google's own OS.

I was also having problems with this. I saw it suggested somewhere that you actually use the word "Appointment" in the event name. I set up a dummy calendar entry for "Dentist" and it wouldn't pop up. I switched it to "Dentist Appointment" and Google now instantly sent me a notification that "it's time to leave for dentist appointment!" Then you can hit the menu button in the top right corner of the appointment card and choose "Yes keep receiving appointment info" voila. Since then, I've always gotten my next appointment, whether it had "Appointment" in the title or not. I also found it wasn't necessary to add the location, it would show up anyways.
