Failed to get mailbox rights. Some or all identity references could not be translated

Question

A service desk user has encountered an error when trying to access shared mailbox delegation. "Send As" is visible however "Full Access" displays red text stating "Failed to get mailbox rights. Some or all identity references could not be translated".

"Full Access" is visible on various other shared mailbox. However this one in particular encounters the error.

Any ideas why this is happening and what I can do to rectify it?

Hello,

This could happen if a user is not set as the owner of their own mailbox in Exchange. Such a situation could occur, for example, after a mailbox migration from an older version of Exchange. The issue can be fixed by running the following PowerShell script in the Exchange Management Shell:

Add-MailboxPermission "<user_DN>" -Owner "nt authority\self"

where <user_DN> is the distinguished name (DN) of the user you are having issues with (e.g. CN=John Doe,OU=New York Office,DC=example,DC=com).

This is what is visible when I use get-mailboxpermission. Everything seems to be ok but still displays the same error in Adaxes

Hello,

According to the screenshot, the account is still not set as the mailbox owner. Please, try running the command we provided in the previous post and check whether the issue persists.
