Teams Calender invitations from shared mailbox

If you send the calendar invites from the shared mailbox they will come from that email. However, it sounds like you want to be able to send the calendar invites from a shared inbox in order to have a common From sender address but you want individuals to schedule and manage the meeting without being tied to using the shared mailbox calendar which everyone has access to. In that case, you can either set up smtp to route ics files through your preferred email domain or use Salepager which can send outlook calendar invites from a shared mailbox such as a team@ or support@ alias.
