Outlook for Mac 2011 Sync Issue


  • I am getting the following error in Outlook for Mac 2011


    The folder Inbox cannot be synchronized with the server

    Details  -----------------------------------
    You must empty the cache for the folder before it can be synchronized again,

    To empty the cache, hold down CONTROL and click the folder In the folder list, click Folder Properties, and
    then empty the cache. If the folder contains thousands of messages, It may take several minutes to
    synchronize with the server.

    Error Code: -19


    Once I empty the cache, the problem appears to be fixed for a short period of time, then when I click on the Send Messages icon, I receive an new instance of the error. I can send emails and use other Outlook features, but no new mail is delivered to my inbox.  I have even tried rebuilding the Outlook database. This too only resolves the issue for a very short period of time. My company was recently migrated to Exchange 2007. I did not use Outlook 2011 before the migration.

    Thanks for any help you can provide.
