i have 13 users that use outlook 2010. we use roaming profiles at my business. i have been dealing with a problem where outlook will not send emails. i get the "outlook data file cannot be accessed" this only happened on one user and i set everyone up the same, and made shure the outgoing server used the same settings as the incoming. i was never able to fix the problem for him, and now with SP1 everyone has the same problem. i also cannot create a new user profile (which was a temporary before). all the computers are windows 7 64bit and outlook is 2010 x86. the server is 64bit running server 2008. if there is any other info that would be helpful, let me know.
