I recently upgraded to Microsoft Outlook 2010 64 bit and the SonicWall add-in fails to load on startup of Outlook. In the Outlook Comm add-in manager it is shown as inactive. Checking the box and re-starting does not solve the problem as the box unchecks itself. There must be a way to point ZA to the new mail location without re-installing it. Any ideas out there from people who have the same problem? I am running ZA 9.1.507.
