Single Exchange 2007 server & about 30 Outlook 2007 clients.Users report no inbound e-mail for 6 hours and testing outbound doesn't work either. No error messages from users reported. Logged in remotely through Remote Desktop to exchange server & received message that local system & boot disk cannot load roaming profile. I clear out the system & boot disk to free up several GB of space.Message Tracking Log shows many e-mails received and sent the past 6 hours. No messages in Queue Viewer.Ran Database Troubleshooter and no problems found.Anyone know where the messages would be? I suspect they are in the Store Driver but I am not sure how to check that.Any help would be appreciated.
