I have been syncing my 8700g with my Outlook 2007 with no problems for a while now. My girlfriend just got one, and she wants to backup all of her contact and calender info with the same computer using a different user account. How can I do this without disrupting my Outlook data? Thanks all!

Yup.

You can even do so with a single user account and two Outlook profiles but I recommend just creating a second user account.

I did same with my wife's new 8100 on an XP machine. I just have her log in in her profile, I do so in mine. Outlook and DM automatically deal with the different profiles.

yes they do and it works just fine. Have me my fiance' and roomate all using it this way Three BB's three accts everyone is synced and backed up
