How to fix MS Teams meeting invitations

Hi,

If people you invite to Microsoft Teams meetings aren’t receiving email invitations, there are a few things you can check to narrow down the cause.

1/ Send a test meeting invitation

In Microsoft Teams, open Calendar, create a test meeting, enter the attendees’ full email addresses, and select Send. Microsoft documents that invitees receive an email with a link to the meeting when you send a scheduled meeting invitation. Reference: Schedule a meeting in Microsoft Teams | Microsoft Support

2/ Check whether the invitations are missing or being filtered

Ask one of the invitees to search their mailbox for the meeting subject or your email address and check their Junk or Spam folder. If possible, test with another recipient to see whether the issue affects everyone or only specific people.

3/ Check the email delivery status

• If the issue affects multiple recipients and your organization uses Microsoft 365, ask your Microsoft 365 administrator to check message trace in the Exchange admin center. This can help determine whether the messages were received by the service, delivered, delayed, rejected, or filtered. Reference: Message trace in the new EAC in Exchange Online | Microsoft Learn
• If message trace shows that an invitation was delivered, the administrator can use the results to investigate further.
• If no matching message is found, additional investigation may be needed to determine whether the invitation was submitted to the email service.

To help narrow this down, could you clarify a few things?

• Do you schedule meetings directly in Teams or through Outlook?
• Does this happen with every invitee or only certain recipients?
• Are the recipients using Microsoft 365 work or school accounts, personal email accounts, or other email services?

With these details, it will be easier to identify the appropriate next troubleshooting step.
