Hey,
First of all let me start by asking you for more info because you provided so little and the error can be caused bij so many different things.
Things like:
- BE Service account not having the apropriate rights.
- Exchange database not in a correct state.
- Connectivity to the exchange server.
- redirection if used, to a nonexisting server, datastore, ...
- ......
What is the version of Backup Exec you are using?
What is the version of Exchange you are using?
How is your exchange setup? Single server, multiple servers?
What kind of restore are you trying to do:
- Complete server restore?
- A Complete Exchange database restore?
- A GRT restore of singel mailboxes, mails, ....?
- Are you doing a restore to the original location or is this a redirected restore?
- Is the datastore/databse mounted or not? Overwritable or not?
