BETA - outlook 2007 B2 - connection to exchange crashes.

[Richard]

I am trying to use outlook 2007 b2 on a tablet pc. It is connecting to
exchange in cache mode. It creates the .ost file and works fine the first
time, brings down all the mail and will allow me to send mail. Then if I exit
outlook and restart. I get the "Outlook has encountered a problem and has to
close" dialog. If I delete the .ost file, then it works again. But only for
that one time.

Exchange Server 2003 SP2, Client OS is both xp xp2 and vista b2.

Ideas?

Thanks in advance!
