Has anyone used a tool or procedure to export/extract chunks of data or whole mailboxes, from GroupWise to PST for use in Outlook?
What tool(s) have you used?
I am really keen to know, how does the GroupWise mailbox size translate to the size of a PST file? is it roughly the same, or does a 1GB GroupWise mailbox end up FAR LARGER as a PST?

We may be moving from GroupWise, after 15+ years, but it's a little way off yet, and I'm starting the ball rolling on considering the obstacles and challenges.

Thanks in advance, Alan
