Thanks so much for the responses, they were appreciated. Since Plan A is apparently not a good one, Here is Plan B. Keep both Office 04 and 08 on my hard drive, which I had planned to do anyway. Set up my Entourage 08 preferences to leave mail on the server, then hourly have Entourage 04 download and delete from the server (which I do now). Lots of redundancy here, but that's not a big deal. I am also open to other workable solutions. Thanks Again Al
