When creating a new user in AD Users and Computers and directing it to create a mailbox as well, it seems that our exchange server never gets the info. Everything goes through successful and it shows that the user has an Exchange Storage group on our Exchange server, but only in Users and Computers. If we look on Exchange, the box never gets created, and the e-mail addresses tab never gets filled on which the recipient policy would normally do. Obviously if you open outlook, it never connects either. Usually when we created a new user, the email box is created within minutes, now it's not doing it at all. I've updated policies and done everything I can think of. The user can log in fine, but for whatever reason, Exchange does get the information needed. I'm thinking it's something to do with the Domain Controller, because it's happening on both our exchange servers at 2 different locations. Email for everyone else, is functioning without a problem. Only thing that changed this weekend, is we upgraded IE to version 6.0 on both the DC and Exchange. Although I can't see how it has anything to do with it. Any help woiuld be great. thanks
