Outlook 2003 SP2 crashes when switching between mailboxes after installing SourceOne Offline Access

Hi All

we are presently at the later stages of migrating from EmailXtender to SourceOne. We are also in the process of migrating our desktops from Win XP with Outlook 2003 SP2 to Win 7 with Outlook 2010. All Win 7 upgraded computers also have the SourceOne Offline Access plug-in to resolve shortcuts and they use the web search for searches. Our XP computers which use Outlook 2003 still use the EX plug-in (EmailXtender_4.81.1459) to resolve shortcuts and they also use the web search for searches. Our present version of SourceOne is "Version: 6.6.1.1315". This configuration works fine and as we migrate computers to Win7 then they are also receiving the SourceOne Offline Access plug-in at the same time.

We are working with a 3rd party implementation company and due to a number of reasons they have advised us that we need to upgrade our Win XP computers to the SourceOne Offline Access plug-in. This obviously involves uninstalling the existing EX plug-in and installing the SourceOne Offline Access plug-in, which again is not a problem.

The problem is that our Win XP users on Outlook 2003 which now have the SourceOne Offline Access plug-in installed, are experiencing problems with Outlook crashing when they switch between mapped mailboxes. More specifically it seems to be when a user switches to the Inbox of a mapped mailbox then back to their own mailbox Inbox. This seems to happen every time when a user switches back to their own mailbox Inbox, but uses the "Favorite Folders" section of Outlook to select their Inbox.

We will obviously take this up with the 3rd party that we are working with but any additional help would be much appreciated and I can supply more details if requested.

Cheers Ste
