Only meeting organizers can make changes (Shared Mailbox)

When a user creates a new meeting from a shared mailbox calendar (Outlook), it seems they can't edit the Teams meeting options.   When they do, they face the following error: "Only meeting organize...

For what it's worth, we have resolved this in our company by making the users also owner of the Calendar.
Add-MailboxFolderPermission -Identity "sharedmailboxaddress:\calendar" -User usermailaddress -AccessRights Owner

Seems to work afterwards, but only when they are working from Office or connected through VPN when working from home, even though the mailboxes are O-365 hosted and not On-Prem.

    Zantas I have tried this but still not working, can you give any more details, does it still have to be the person who organised the meeting or can you add anyone in as owner and update the meeting options.  Is there a particular way to access the meeting options?

      chrismai This is entirely possible to get working - Our team has spent a few days on this with MS support and got nowhere, but managed to find a fix.   

       

      1) Enable the AD account for the shared mailbox  (by default these are disabled and I believe this is 99% of the problem)

      2) Grant the user full access to the mailbox

      3) Grant the user Owner level permissions to the :\calendar folder in the mailbox via powershell:

      add-MailboxFolderPermission -Identity "sharedmailboxaddress:\calendar" -delegateemailaddress -AccessRights Owner

      4) Wait 24-48 hours.  Within a couple of days, it'll start working.

       

      I also found a temporary workaround for this:

      1) Get the user to create a blank calendar entry in their calendar first.

      2) Copy the blank entry from their calendar to the shared calendar (drag and drop in Outlook)

      3) Open up the copied entry, and edit is as usual.  The meeting options will be available.

       

      Hope this helps.

        Hi the workaround only works for the original creator of the meeting (since the Teams meeting belongs to them) and won't work for any delegate of the shared mailbox.

         

        I'll give a try to your first solution.
