I installed this on 7 and found out that MS doesn't have a PFbackup for 7 yet, no surprise considering the newness of the OS so I could not import my personal files to Office 2007. That being said I uninstalled it and installed office 2003 then I imported my backup files and had my data just like in XP. Then I installed Office 2007 and it overwrote 2003 and I had all of my data, cantacts, emails, deleted emails, etc. I almost pulled my hair out before I tried this solution. The thing to remember here is that this is a beta and the developers can not think of everything. Thats what feedback is for. So far I am really Impressed with 7 and really frustrated at the same time. So far, so good.
