Hi @Malone, Andrea ,
Welcome!
According to your description, sounds like you encountered an issue that manager cannot receive meeting invitations sent to him but delegates can , right? If yes, I would like to check how did you grant the Delegate permission before, via Outlook > File > Account settings > Delegate Access? Or from your server side?
If your manager granted the Delegate permission via Outlook > File > Account settings > Delegate Access, issues like this might indeed happen when selecting "My delegates only" option like below.
From Outlook for Mac side, this option looks like below:
If this is your case, please try to modify the settings above and select the "My delegates and me" option to see if your issue could be resolved.
