We run Exchange 2003 as a virtual server using Hyper-V. Recently accidentally formated the drive on the host server containing the virtual servers, including this exchange server. Recovered using backup, and everything is fine, except some users are not getting any incoming e-mail. No internal mail or external mail. Cannot see the mail when logging in through OWA either. However, the affected users CAN send e-mail to anyone. In our total organization, I would say 80% of all users are totally fine with e-mail function, while the other 20% can only send but not recieve. It is not the Outlook clients. Any ideas?
