Activesync error 0x85010017 on X1 with Windows Mobile 6.1

[bizman928]

My Sony Xperia X1 has been syncing fine with my Exchange server for several months but since the USA upgraded their server last weekend I cannot sync and keep getting error codes.

I have the following information from my USA server manager regarding what changed during the upgrade:
----
Old server: Exchange 2003sp2 front-end
New server: Exchange 2007sp1-ur8 CAS+HUB

The address did not change

The certificate is valid.
-------

I have tried to delete my PC device and the exchange server on my phone and then reboot both, but this doesn't seemt o have helped with anything?

Any help would be appreciated to get my X1 to receive emails again.

Thanks
Steve

I deleted the device on my laptop and also active sync connection & settings on my phone, power off on both and new restart on both.

My phone has sync'd all my contacts & files OK but Microsoft Exchange is still not working.....

The problem can be third party application like i had this error because i had installed translator program so after uninstalled it no problem. another things you can try change the view on Calendar to show All Appointments and then delete 6 duplicate calendar. This error might be caused by the presence of a large volume of items in the first synchronization. Or, the error might result from specific large items, such as calendar items with many meeting attendees.v check here http://support.microsoft.com/kb/915152
