I am using Exchange 2003 SP2. Since a week, it as crash 3 time with this error: MAPI or on unspecified service provider. ID no c1050476. See image for complete error.
It seems to always happen during the backup. We are using backup Exec to backup the store. The backup seems always stop at the same spot. After a server reboot, all is well again.
What can be the problem and how to resolve this?
