This is my third install of Office 2007. The first two were B2TR and worked
fine. Tonight I installed our first copy of the release version and have had
a couple of major hiccups. Problem #1 were constant long hangs and--after
checking some tech notes posted on the web--were fixed by turning off client
to server encryption.

The second is more problematic and I haven't found a cure...only a tech note
posted that someone else has the same problem.

Every thirty seconds--endlessly--Outlook pops up an error message stating "A
data file was not closed properly. Perfomance might be affected while Outlook
checks the file." And sure enough, Outlook then hangs for 5-10 seconds or so.
Endlessly.

All three of these machines are looking at the same few mailboxes on the
Exchange server; this is the only machine that is reporting problems. I
uninstalled and reinstalled--same problem. Created a new profile--same
problem.

All three of these machines are running WinXP SP2.
