I am in a crisis. Last night I performed regular updates on my Exchange server (2010) and was forced to reboot.
I also rebooted the BESX server , which happens to be one of two DCs and one of 3 DNS servers.
The DC's are server 2008 and the third DNS is Server 2003. The2k3 box is the OLD DC but is still not totally ready for removal as all services are not fully migrated.
After reboot, I tested mail flow and confirmed it was working. I also tested the admin account using Outlook.
Now all 40 plus users are having issues connecting to Exchange. All Outlook clients get the same error: 0x8004011d .
In order to get them back up, I had to recreate all Outlook profiles and NOT attach the profile to any other mailboxes but the user's own. (there is ALOT of mailbox sharing as some users are assistants to other users)
No mailbox can connect to another mailbox even though the permissions are set in sharing in Outlook.
PFDAVAdmin does not work and I am pretty weak in Powershell.
I have checked DNS by pinging the mail server by name from random machines and all machines can find the mail server.
OWA works as does Active Sync and I believe all users in BESX.
I am very baffled and need much guidance.
Thank you in advance for any and all help.
