Try opening the shared mailbox in OWA and schedule the meeting there. If it works fine in OWA, let us know how you are accessing the shared mailbox in Outlook, what permissions you have, etc. If you are not able to create it in OWA too, check your permissions on the shared mailbox.

Are you able to schedule a Teams meetings from your own primary mailbox in Outlook?
As mentioned by michev, how about opening the shared mailbox from OWA and see if you are able to create a Teams meeting there?Please make sure you have been granted the both the "Send as" and "Read and manage" permission to the shared mailbox. This can be checked via Exchange admin center > Mailboxes:
Additionally, if it works fine in OWA, please try the steps below and see if it can help solve the error occurred in Outlook:
- Quit Outlook and Teams.
- Reinstall Teams via https://www.microsoft.com/en-us/microsoft-teams/download-app.
- Launch Teams, click the Teams avatar at top-right, choose Check for updates, wait for a few minutes for the process to complete. Quit and relaunch Teams.
- Launch Outlook again and check the result.

2025-06-14T22:48:43.9733333+00:00 Try logging into the shared mailbox directly and scheduling the meeting that way rather than through your personal email or try scheduling through the web app if you have adequate permissions. If you want the invites to come from a shared inbox without having to log in the shared inbox you can set up smtp to route calendar invites from a designated sender address or use Salepager which lets you send Outlook calendar invites from a shared inbox or desired team email address as the "From" email.
