Need some advice. Server crashed last night and upon restarting this morning, no email.
Event logs show that information store is not being mounted, ala :
"The MAPI call 'OpenMsgStore' failed with the following error:
The Microsoft Exchange Server computer is not available. Either there are network problems or the Microsoft Exchange Server computer is down for maintenance.
The MAPI provider failed.
Microsoft Exchange Server Information Store
ID no: 8004011d-0526-00000000 "
I can start the Microsoft Exchange Information Store service, but from the server management console, I cannot mount the stores as the option to mount is greyed out. Had issues once befopre on this server a year ago and resolved by restoring exchange store from backup and running eseutil and isinteg. But the the event log messages are different this time and the backup is 5 days old so I don't want to run the restore to find the issue is something different than a corrupt store.
This server is a single domain controller.
I'm fighting the clock here as I know these repair utilities can take all night to run, if it needs to be done then I want to run it immediately, but want to take onboard your opinions first.
