I have a Mac Book with Parallels and XP installed. Office 2007 Enterprize. From within the domain I can retrieve exchange mail without a problem. When I attempt to connect remotely utilizing a sonic wall vpn connection I get the above error. I have uninstalled Office, cleaned out the registry then did a fresh install with the same error. I have deleted the ost files and redid connection with the same message. I personally use owa but this user is and exec and refuses. I have searched extensively through the knowledge base here and abroad and tried the fixes that I have found. Any help would be greatly appreciated.
