Tested with Archive Manager 6.1 and Outlook 2010.
Normally a Public Folder is required to publish the Outlook personal forms that the Archive Manager Outlook addin uses.
To work around this, import the following registry key at (each) user logon:
Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Metalogix\PAM4Exchange Outlook Addin] "PERSONALFORMSPUBLISHED"=dword:00000000
This forces the Archive Manager Outlook addin to re-import the personal forms without requiring a Public Folder.
