Mailbox Converted to Shared Mailbox doesn't show in Add Objects to a Backup Job

[goldstar4]

Recently i converted a user Exchange mailbox to a shared mailbox. I would like to backup this mailbox in Veeam Backup for Microsoft Office 365. When I edit a backup job under my organization, then add object from menu, I see some shared mailboxes, but I do not see the converted shared mailbox I want to backup.
Any ideas?

It sometimes takes some time to reflect this update but you should be able to see it. Are you still unable to see it listed?

What's interesting in my case is that when I go in to add a shared mailbox in Veeam Backup for Microsoft Office 365 I no longer see the type "Shared Mailbox". I used to see this type prior to upgrading to version 5.0.2.42, but now the only type I see is "User", even though I have hundreds of shared mailboxes in 365.

Are you using the modern app-only auth for backing up your organization?

[SCOIT]

Yes.

It explains. With this auth method, Graph APIs don't allow to identify 'shared' mailboxes and return all users with the 'user' type.

Ahh thanks for the info Polina, that explains it.

Other than adding all shared mailboxes to a group, is there any other way to differentiate the shared mailboxes from the user mailboxes when setting up a backup job in Veeam for O365?

Not that I can think of...
