We upgraded server to Zimbra Network edition 7, and created new Profiles in Outlook 2010.

And started to get different problems/issues
- outlook crashing
- cannot change/select correct Outlook profile (Outlook started profile on "his own", no matter, what was selected in Control Panel Mail).
- editing HTML Signatures crashed - inserting images in HTML signature, worked only for the first time, after that - all files from AppData/../Signatures/default_files/* was "deleted".

Issue resolved only after I found to uncheck "Sync Signatures" into Zimbra Advanced settings in Outlook.

Is it Bug? We had it on 4 computers - All are using Outlook 2010 and Windows 7 (different - 32-bit and 64-bit).
