[SOLVED] Sync with MS Echange issue

[Regger]

Error occurs when setting up an IMAP with MS Exchange. I tried to reset and start over, but the same error occurred. Two folders received 219 mb and 293 mb before the error.

UPDATE:
Problem solved. Issue was a message with a bad format.
I isolated the problem by determining which folder was causing the problem. I made a new folder and move messages from the Bad folder to the New folder. I moved 25 messages (using OWA) at a time and sync Zimbra after each move. Once the folder gave an error on the sync I looked at that set of 25 messages. I used Evolution with an IMAP connection to see which email had an IMAP4 issue. One message stated there was a problem with IMAP4. An alternative work around is to search the folder using Evolution for "IMAP4" in the body of the message text.
