Update mailbox permission for mailbox failed
I tried to add a user to a shared mailbox as "Send as", but I got the following error: Update mailbox permission for mailbox failed Any suggestions to fix my problem?
Try again, it's probably some temporary glitch. You can also try via a different interface - if you have tried in the admin portal, use PowerShell or vice versa.
Hi,
unfortunately the problem is still there, but I haven't tried it with Powershell yet. Do you know the command to give a user the permission to "send as" for shared mailboxes?
I couldn't really find anything in the command in the documentation.
The cmdlet you need to use is:
Add-RecipientPermission sharedmailbox -Trustee user@domain.com -AccessRights SendAs
