I have been using Version 10.1 of MS Entourage (MS Office) for some time now, and have had to rebuild the database once so far. I guess I should have been doing this periodically, but now am being forced to do it, again. The problem is trying to find the space on the system HD to do that. I have moved alot of music and digital photo files onto an external HD, and have freed up some 40 gig of space on the start up HD. For some reason, it is still not enough (I think my database is no larger then 10gig) and I can not get this software to rebuild the database, hence I can not access my emails using Entourage. Is it because my HD is too fragmented for entourage to use it for this purpose? Is there a way to defragment the HD (I'm using OSX v 10.2.8)? What's the deal? Thanks.
