"Client/Server conversion error" ruining my Desire experience

brenny,

I can't seem to resolve this issue? I still get the client/server conversation error message?? Any help.. This phone has been working flawlessly for two weeks then it just decided to stop getting exhange mail so I deleted and readded the account and then i was getting the calendar sync errors!

HELP
 
Do you still see appointments in the calendar when you cleared all the data in the "Applications" section? It should be empty before you add the exchange account again.
 
Let me add my thanks to Brenny. I had asked our IT guy here at work to look into this for me. He has an Android phone, too, after coming over from the iPhone. It was great to be able to call him and let him know that I had found the naswer on my own!! I am grateful to have found this forum.
 
Thanks to those above who suggested this fix. It was very useful, but I think there is an even easier to correct this. You don't need to remove the Exchange account. Here is what I did to fix this.

1) Removed data from Calendar, Calendar Storage, Calendar Sync Adapted and Calendar Widget (basically anything with Calendar in) using Manage Applications under Settings/Applications.
2) Opened Settings/Accounts & Sync/Exchange Active Sync and unticked Calendar sync.
3) Did a "Sync now" which therefore just sync'd mail and contacts.
4) Ticked "Sync Calendar"
5) Did a "Sync now" which sync'd mail, contacts and calendar.

Problem had gone away. I actually believe this is a problem with the Exchange Activesync profile as something pretty similar used to happen on my Nokia (which uses Activesync, as does iPhone) and I used a similar method to fix this but I can't be sure of this.
 
Thanks so much, Andy W_Desire - I'm hoping that this will work for me - I was talked into Touchdown by my IT guy as well, but I really preferred the native app - now the only thing that we have to work on is to get Tasks and Notes to show up within that app ;)

I think if Brenny took a sledgehammer to this problem, AndyW_Desire took a scalpel and managed to slice just the right problematic bit out :-)

Thanks!

This worked for me and I didn't want to delete and set up the account again in case I hit the problems some others have had because of that, reading this thread and others.

cheers

I have absolutely the same Problem jonrosenfeld marked out (see quote). In my case I did not tried to make a calendar entry through the phone. - But I installed MyPhoneExplorer Client. Is it possible that that compromised/affected the calendar? If I deactivate the calendar syncing - email and contacts still keep working.

By the way - I use a HTC Desire Phone with Android 2.2 / HTC Sense.

Thanks in advance for any help!
Greetings, Sammy

I've had a Desire for two weeks now. I was in love with the phone... until this problem came up.

I use Outlook and Microsoft Exchange -- and had read all about how Android synced easily. And it did at first. Then, 10 days ago, the calendar stopped syncing. I got a "Client/Server conversion error," and no sync. The problem only effected my calendar -- mail and contacts were synced just fine. After reading a few forums, I did a "Remove account," re-installed the account. It worked fine again. No big deal.

Then it happened again today. I did the Remove/re-install thing again, and again it was cured. Until six hours later.

Is anyone else having this problem with their calendar/exchange sync? Any solution guesses?

Help! Without being able to sync my phone to Outlook, the Desire I love so much is somewhere between frustrating and infuriating.

Thanks in advance,
Jon
 
I had the exact problem. If I put in a calendar event in my EVO it would update outlook but not in reverse. I followed Brenny's suggestion on this forum and it has worked so far.

One thing I did notice was that I had accepted a calendar event that was recurring but only for a period of time. It was shortly after that where I began having the problem. Now that I have reset my calendar I've notice that all my calendar events seem to have sync'd except for that one recurring event. Not sure if that is the glitch but looks like it on my end.

I have the same Problem, I try several things, thanks till know its fix.

I delete Exchange Active Sync on my HTC and re install, still not sync

I went in HTC Desire Settings/Application/Manage Application/All/ Calendar/Clear data/ Force stop not sync, I went to all the places on the phone to delete the calendar information, but without success, and still have information in my HTC calendar.

I Clean my calendar in Outlook and still not Sync. (Copy all the information first and paste them in Excel.)

I Re install office on my computer, still not sync

I Re install windows still not sync.

My last option was, go in my HTC/Calendar, Month view and delete 1 by1 all the information in the calendar from this month till when I see nothing more including all recurrence (I reach till 2013) Than I went in the past starting from December 2010 in the calendar and delete every single appointment and I realize that I have old notes till 2002 in my calendar and some of the recurrence till that year. From there I went till 1997 just to double check if I don
 
I'm synchronizing my Android (HTC Desire) via company Exchange server, not USB and I keep getting a persistent calendar sync error when I - on the Android - modifies or deletes one occurrence of a REPEATING appointment originally created in MS Office Outlook.

My workaround is to delete the repeating appointment in Outlook, sync on Android and then recreate the appointment in Outlook.

I'm puzzled why noone ever diagnosed this on Android (HTC only?, Desire only?) and fixed it...
 
I got "Client/Server conversion error" when I tried to add certain events on my Desire HD, then tried to sync it.

I've figured out that this happens for the following two scenarios:

1. When I've entered something in the Description field.
2. When I've tried to create repeating entries.

I haven't figured out how to fix this (all that removing accounts and deleting calendar data does is delete the event in question). My best way to get around it is to create the entries in my Outlook Exchange account then sync it to my phone.
 
The 'scalpel' approach of AndyW_Desire didn't work for me. The calendar data deleted fine, then when I tried to re-sync the calendar to pull back the data nothing turned up. Removed whole account and re-added as per Brenny and all is good now.

I think I know what caused it for me. Outlook can add in lists of national holidays in to your account. I deleted one from my Desire but noticed that it didn't go from outlook. It didn't seem to want to give up the event from the exchange calendar because it was part of this national holiday list, and then the sync issues started. Deleting a normal event from the phone is fine. I add, delete and modify from both and have never had a sync error before.

It would be good if there was an error log for activesync so we could see which calendar entry was causing the problem and adjust/delete it from the exchange server.
 
The AndyW_Desire method worked for me and I'm pretty sure the problem started after I altered a single occurrence of a recurring event from the phone.

Thanks!

I started getting this error a few days ago. This is what worked for me - and I didn't have to remove the entire Active Sync account.

1. Menu > Settings > Accounts & Sync > Exchange ActiveSync
- Uncheck 'Sync calendar'
2. Sync the Account
3. Menu > Settings > Applications > Manage > All
- 'Calendar' : Force Stop, Clear Data, Clear Cache (if avail)
- 'Calendar Storage' : Force Stop, Clear Data, Clear Cache (if avail)
- 'Calendar Sync Adapter' : Force Stop, Clear Data, Clear Cache (if avail)
3. Sync the account again, get there just like in step 1.
4. Verify the calendar is empty.
5. Menu > Settings > Accounts & Sync > Exchange ActiveSync
- Check 'Sync calendar'
6. Sync the account.

After I did this I had no more errors. I do believe it has to do with recurring Outlook appts and trying to edit them, delete them, or do anything with them from the Android client.
 
In my case I have run into this problem twice on my HTC Inspire 4G. Both times it was caused by adding a calendar entry from Android that was sent as an attachment via exchange email in the form of an .ics file attachment. Opening the attachment seems to do the right things on Android, but from that point forward calendar sync doesn't work correctly.

As an example, yesterday evening I added one of these calendar entries sent via email attachment and this morning noticed I was having this calendar sync issue. I then remembered what I had added last night, deleted it from my Android calendar and manually initiated another sync and things went back to normal. This probably isn't the only situation that causes this problem, but it seems to be a guaranteed way to cause it to happen twice now on my phone.
 
Hi,

I tried dave_mwi's approach and did not get a sync error but noticed that not all my Exchange appointments were transferred to the phone. All past ones were but none of the future ones. I also noted that when I went in the Calendar app & I went o Menu, more, calendars that the only calendars listed were the Google calendar and the PC sync calendar, the exchange server calendar was not listed as an option although there were some appointments.

When I tried the steps again I ended up with no exchange appointments being transferred back to the phone.

When I deleted the account, deleted all application data and recreated account all seemed to be OK.

Thanks everyone for their help.
 
Thanks everyone for all the help.

A 'super scalpel' approach worked for me.

1. Check my sent items folder
2. Noted the message that showed my last response from my calendar
3. Opened message to check date of appointment
4. Went to that date on phone calendar, noted a duplicated appointment - deleted both appointments
5. Re-sync - bada boom bada bing - problem solved.

I remembered that I had updated a single meeting in a series on the phone directly from within the calendar app - won't do that again!
 
I registered just so I could THANK YOU--especially Brenny--since I had this problem on my Thunderbolt recently. Grear group you are :)
 
dave_mwi: you da man!! I think I narrowed my problem down to every time I accept/decline an outlook exchange appointment from my phone, it throws my Droid Incredible into a tail spin. Following your advice has it flying the friendly skies once again. Thanks!!!
 
This is what worked for me

1. Menu > Settings > Accounts & Sync > Exchange ActiveSync
- Uncheck 'Sync calendar'
2. Sync the Account
3. Menu > Settings > Applications > Manage > All
- 'Calendar' : Force Stop, Clear Data, Clear Cache (if avail)
- 'Calendar Storage' : Force Stop, Clear Data, Clear Cache (if avail)
- 'Calendar Sync Adapter' : Force Stop, Clear Data, Clear Cache (if avail)
3. Sync the account again, get there just like in step 1.
4. Verify the calendar is empty.
5. Menu > Settings > Accounts & Sync > Exchange ActiveSync
- Check 'Sync calendar'
6. Sync the account.

I'm having similar issues with an HTC Merge, both contacts and calendar were not syncing, except I got the error: "error occurred on the computer running the exchange server."

I tried the suggestion above and that got the calendar running again, but contacts still won't work. Any suggestions?

Well, since this is a work phone and he needs his exchange items, we started looking at other options than using active sync. What we came up with might help others, so I thought I'd note it. I'm not sure if will work 100%, but it seems like it should.

1, Create a 2nd Gmail account that'll be used just for work. Most people use a firstname.lastname format, so I suggested firstname.work and added that account to your phone. Depending on which functions do/don't work, only sync those items that are needed. In our case it was only contacts.

2. Download and install Google Apps Sync for Microsoft Outlook
 
1. Delete the Exchange Activesync account.
2. Clear the data in Calendar and Calendar storage (Menu --> Settings --> Applications --> Manage applications).
2. Add the Exchange Activesync account again

IMP: Step 2 is critical as deleting and reinstalling the Exchange Activesync account does not remove Calendar entries and problem will persist .
