    Dai_Webb Hi! Then I would walk through this step-by-step https://docs.microsoft.com/en-us/microsoftteams/exchange-teams-interact#requirements-to-create-and-view-meetings-for-mailboxes-hosted-on-premises

     

    Note the "To enable calendar delegation for these users" section as well.

Was able to repro this issue in our environment.

Seems like assigning -AccessRights FullAccess causes the issue

When this was removed and we left only delegate rights for calendar it works.

 

For our environment we tested in the following scenario:

- both user A and B (delegate and delegator) were o365 users

- both were on Office Pro Plus using Outlook 2016

 

Users didn't complain about this previously because we've only recently introduced Teams into our environment (we still have Skype but it is being phased out) And as another person in this forum mentioned, Skype meeting and regular meetings are not impacted.

 

To get this working:

  • User A must give User B calendar delegate permissions in Outlook
  • ensure that -AccessRights FullAccess has NOT been applied
  • When User B adds the calendar in Outlook it needs to be done through: File > Open & Export > Other User’s Folder

Note:  some of our users - we have EA's that not only manage calendars for their executives - also need access to their Inbox and want it to appear in Outlook beneath their own mailbox. So for these users we ensured that 'Inbox' permissions were also delegated. Then User B went into Outlook to add the mailbox through: File > Account Settings > Account Settings > New   ....when prompted select 'Office 365'

    This is the solution:

     

    Teams meeting in Shared Mailboxes does not work with Automaping Shared Mailboxes.
    Shared mailbox has to be added to Outlook manually as an additional account for it to work.

     

    Remove the shared mailbox access in EAC, via Powershell assign full access permissions with automaping off

     

    Add-MailboxPermission -Identity "SharedMailbox" -User "Username" -AccessRights FullAccess -InheritanceType all -AutoMapping $false 

     

    Add the shared mailbox to Outlook manually.

     

    Best regards,
