Backup Exec 15 restore to Exchange 2016 mailbox fails as EWS error/credentials error

Hello,

I currently have the following problem:

If I want to restore a mailobject from a full backup of our Exchange 2016 databases it fails with the following error:

Final error: 0xe0000388 - Cannot log on to EWS with the specified credentials. Review the resource credentials for the job, and then run the job again.
Final error category: Resource Errors

So after this I checked the credentials and the DAG host says "Test failed, Test recommended", which is weird because backups work without a problem, which shouldn't be, right?

I then found this article and checked all the steps, which seem to be OK (I even put the account I have configured for the backup in the administrators group on our CAS servers), the only difference being that it is not our default account, but I have tested it with the default too and the result is the same (i.e. the test fails).

I have also checked the EWS login with https://mail.domain.com/EWS/Exchange.asmx and I get the service page, so the login does work.

Does anyone have any idea how to fix this problem?

I would suggest starting off with making sure the account being used has all the proper permissions.

I have added the missing permissions according to the article and also set the role assignment.

The issue persists however.

what type of "mailobject" are you attempting to restore?

Are you going back to the original location or redirecting it to another mailbox?

If it's redirecting is that mailbox hidden?

In my testrun I am attempting to restore a deleted mail to my own mailbox. It's the original mailbox and not hidden or anything.

Any chance you could use SGMon to debug the BE server and Exchange server during the restore and attach those for review with the failed job log?
