I’m using Backup Exec 20.3 and Exchange 2016 CU12 both up-to-date on Windows 2016
The Backup works well, when I try to restore individual mails to a mailbox, I get the error “0xe0000388 - Unable to connect to EWS with specified credentials”.
I’ve already read a lot of older Posts, and checked the rights, the mailbox and the account. I am using the default DOMAIN\Administrator Account to backup and restore. The Backup Server is in the same Domain. The mailbox is not hidden. EWS works when I try it with the Website.
Any suggestions? I’m running out of ideas... Thank you very much
