I am facing an issue with Microsoft 365 Exchange Mailboxes backup. I am successfully backing up most of them, but I’ve recently detected that a few of them are still not included in the scope. First idea was that I just skipped them accidently, but after another attempt to “Add Mailbox” > Put a tick next to a target > Save - that did nothing, regardless the popup message confirmed that “Successfully Updated the selected User Mailbox”. We have a few similar cases and the only common thing I could notice between all these mailboxes that all of them had another mailboxes with the same name already being backed up. For example a user owns two mailboxes - firstname.lastname@example.org and email@example.com, both of them have Names “User Name”. I would like to have them both backed up, but here I face that issue, that I am able to Add only one of them, while another stays unselected.
I hope I was able to put everything down clear enough and you’ll be able to give me a hint how to workaround this one. Thanks in advance.
