I am trying to set up a teams meeting and invites don't go out

Hi @Mark Monsen, 

I hope you’re having a great day. I appreciate your patience and the details you provided. 

A - What's happening 

From what you’ve described, the Teams meeting is being created successfully, however the meeting invitations are not being delivered to the people you invited. I’d like to clarify that when a Teams meeting is scheduled, the invitation emails are actually sent through the Outlook / Exchange calendar system in the background. Because of this, invitation delivery can sometimes be affected even though the meeting itself exists and appears correctly on your calendar. 

B - Recommended next steps 

1/ Check Junk / Spam / Quarantine folders 

First, please ask the invited attendees to check their Junk, Spam, or Quarantine folders. In many cases, Teams meeting invitations can be filtered or blocked by organizational email security policies, particularly when inviting external participants.  

Even if no error appears on your side, the email may still be stopped by the recipient’s mail system. 

2/ Use the meeting join link as an immediate workaround 

If you need an immediate workaround so the meeting can proceed as planned, you can copy the meeting’s Join link directly from the Teams meeting details and send it to attendees via email or chat.  

This allows everyone to join the meeting even if the calendar invitation email was not received. 

3/ Check the Microsoft Teams Meeting Add‑in in Outlook (Windows) 

If you scheduled the meeting using Outlook on Windows, the issue could be related to the Microsoft Teams Meeting add‑in. After updates, this add‑in can sometimes become disabled or stop working correctly. I recommend signing out of Teams and restarting it, then closing Outlook completely and reopening it.  

In Outlook, please also check that “Microsoft Teams Meeting Add‑in for Microsoft Office” is enabled under File > Options > Add‑ins > COM Add‑ins. 

For additional information, you can refer to these articles:

C - Contact Support 

If the issue continues to occur for multiple recipients or across multiple domains, please contact your organization’s IT team so they can review the email flow and check whether the Teams meeting invitation emails are being blocked, filtered, or rejected by the mail system.

In case your IT department cannot access the necessary information or make the required changes, I recommend asking them to open a request with Microsoft Support team through the Microsoft Admin Center. They have access to backend configurations and can perform a more in-depth investigation. At the very least, they can provide the most effective workaround to ensure your experience remains smooth and secure.
