Fix Signature error in Outlook after Zimbra 7 upgrade
The following problems were encountered while synchronizing signatures:
- Failed to push signature 'Retreat' to the server
- Failed to push the linkage for signature 'Retreat' to the server
In Outlook go to View -> Toolbars -> check Zimbra Support
In the Zimbra Support tool bar click Advanced and uncheck "Sync Signatures."
That will disabled the signature synchronization to the server and should remove the errors you are experiencing.
