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] Exchange Calendar Sync Issue - Resolved

Stock EVO, 2.2...
I just noticed this issue about three days ago...my Exchange calendar is constantly syncing, and I do mean constantly.
If you go to Settings - Accounts & Syc - Exchange ActiveSync, you can see the last sync for each item. My calendar constantly reads the same time as system time, and the Sync icon in my notification area is constantly flashing on and off.
I have noticed that my battery is draining VERY fast. I had to put it on a charger twice yesterday (I got the 15% battery warning) with normal use, when I can typically go a full day of use without any issue.
I can deselect Calendar syncing, but of course that's only a temporary fix.
Has anyone else run into this? Anyone heard of a solution? A google search did not yield any results.

FIXED!!!
Well I fixed my own problem...though I cannot determine the cause of the issue (I even tried uninstalling some apps I had DL over the past few days), the fix was simple, though it took a while to figure out.
I tried to merely remove/re-add my Exchange sync, but I kept getting 'client/server conversion errors', and my calendar would refuse to sync (though email and contacts did). Furthermore, in Outlook, I would get lots of duplicate entries (interestingly, they were recurring events and all-day events).
This was the solution:
1. Delete Exchange account from EVO (contacts, calendar, email)
2. Since I noticed that my calendar app still had some entries in it, even after deleting the Exchange account, it was evident that there was some data still on my phone that was possibly causing the syncing error. So, I went to Settings - Applications - Manage Applications, and selected the All tab. Scroll down to the 'Calendar' app entries, and you have to clear/delete any cache/storage data in each.
3. Re-synced with Exchange successfully.
I searched around different forums, and it seems many have had a similar issue and have waited in vain for Sprint or HTC to publish a solution.
This one worked for me. Hope it helps others.

yes!!!! Thank you so much. After trying everything and almost a week of my battery going dead with a couple of hours on my EVO your solution worked! I would recommend that anyone try this solution before going any further!

ICS calendar sync issues solution

Not sure if anyone else is having problems in ICS builds with google calendar sync but I found a solution that worked for me. I tried different apks with no luck the problem it seems is that the ICS calendar has trouble displaying certain recurring events that GB seemed to handle fine for me. After exporting my google calendar, deleting the calendar, and then importing the saved file back into google calendar I was finally able to get ICS calendar to sync. Google how to import and export google calendar if you don't already know how, it's quite simple. If this doesn't work you can try deleting reoccurring events till you find the one causing the sync error.

ICS with Exchange
I am facing the same problem with my exchange calendar sync. Do you think this solution would work for this as well?

There's an app for it
I had this issue after updating my Galaxy Note to ICS 4.0.3. Calendar sync caused forced close and no data was synced. Tried deleting my corporate google account from the phone and re-adding it (my personal account synced just fine).
Bought an app called CalenGoo for less than EUR5 after confirming with the very helpful dev that it is not reliant on the defective ICS sync engine. Got everything up and running in seconds!
On other suggested "solutions" found on forums: 1) Not intrigued to factory reset the phone and restore all apps and lose their settings etc. while there is no guarantee that it would do any good. 2) Deleting recurring events (weekly meetings with colleagues etc) is simply not something anyone who uses their Google calendar for anything serious is going to do. And again no guarantee that adding the meetings again would not just cause the same problem. Rather buy a phone that works. It is ridiculous that Google/Samsung would release this kind of defective crap, and makes you think what else might be wrong with ICS if QA is this bad.

Another Fix - Change/Delete Daily Recurring events with Every Weekday Selected

I was having this Google calendar sync error constantly on my Samsung Galaxy S3 and Asus Transformer TF101 tablet. I used ALOGCAT to pinpoint the root cause although it was misleading because the log said "Weekly" recurring event when it was actually a "Daily" recurring event with "Every Weekday" checked. If I deleted these entries or changed it to a Weekly event and picked each weekday specifically, the sync errors stopped. Here's more detail on my approach. I use Gsyncit to sync between my work pc Outlook account and my Google calendar. Then I use the normal sync apps on the phone and tablet. As part of my troubleshooting I had deleted all my Google calendar entries, then reloaded the events from Outlook to Google (one way). I still was getting the sync error until I located and changed the offending recurring events. I also removed my Google accounts from my phone and tablet to force them both to load all the recreated Google appointments from scratch. This may have been overkill. Try removing or changing the Daily (Every Weekday) recurring events, first, before wiping your calendars like I did. If doing just that works for you, it will save you a lot of time.

ICS4.03: Email exchange issue?

My email worked fine with Exchange server in Gingerbread but since I've upgraded
to ICS is not working ok, it doesn't download all emails and I keep getting
"Connection Error" messages.
Who else is having issues with Exchange server in ICS4.0.3 ?
Can we report this issue somewhere to Samsung?

Got the same problem, contacts and calendar syncing, also in two days i got 3 emails on the device as well, but the oldest ones. Have bought Enhanced Email and is working perfect.

Mine is fine on bone stock LP7 or LPQ
check the exchange server for errors if you have access. the mobile device policy might be doing something funky

Problem I'm having is that when I configure my works's exchange environment settings, only the email and the contacts synch, the calendar is not synched at all. Same problem with the Enhanced Email app only mail and contacts and no calendar? Is this something with ICS specifically or with the kernel LP7.

running STOCK LPF with XXKL1 Baseband. was experiencing battery drain. apparently its a known issue with ICS 4.0.3. Tried couple different things and deleting account and re-adding seem to do the trick for me at this point

Same here

Having the same problem. Mail/contacts sync like a charm, but the calendar just gets stuck. Lot's of wakelocks when I enable it too...
Have been searching my *** off to get this fixed, but thus far, no solution. Tried re-adding the account, even wiping the whole phone, installing AOSP calendar/mail... nothing helps
A search on Google taught me it was a 4.0.3 bug btw, and google is kind of neglecting the whole thing :/
Bottom line is, you need to delete ALL of your reoccurring events. That's the only one i haven't tried yet
Edit: Just tried it, it worked! I just deleted some random events which were really old and sometimes in Outlook 2011 giving some problems with reminders. Now my calendar is syncing again. No wipe needed btw
What I did:
In outlook 2011 for OSX (but can be any mailclient) i created a local folder. I searched for reocurring events, and started moving them one by one to the local folder, which removes them from exchange. Every 3 items, i tried sync again, and after a few tries, my calendar started working.
The problem for me was with some birthdays, which were added from the contacts by my HTC Desire in the past

Hi,
I'm experiencing the same issue, i.e., duplicate instances of a single appointment. My MS-Outlook account is through my work so the settings are pretty much fixed. I have the account setup to push updates to my device. Here's an example of what's going on. Today I created a single one time instance of an appointment on my MS-Outlook client from my Laptop. When it arrived on my phone is shows on my calendar as 15 instances of the same meeting. Then like 10 minutes later I deleted the one instance of the meeting from my Laptop MS-Outlook client and it won't delete or remove the 15 instances from my phone.
Any help is greatly appreciated.
Thanks
Steven

For me the following finally helped..(after discussing with Samsung Developer Support)
backup all you calendar items in outlook using separate offline calendar.
once all items moved from this calendar do a sync.
then one after the other try to move the appointments back.
I tried with 3 appointments and since it worked with those 3 I moved all remaining at once (around 1000) and it worked
hope that helps
