external teams meeting invites get deleted

FROM CUSTOMER

We have calendar processing external meetings set to true.

The behavior is when an external teams invite is sent to sfmobileroom@byer.onmicrosoft.com.

The invite is removed from the calendar.

I expect the calendar to accept the meeting.

ProcessExternalMeetingMessages : True

The external invite is coming from a Teams account.

Please see attached invite which was in the deleted folder.

We have faced this issue 2x….the first time we looked up settings enable.

This time all settings appear to be enabled and we still seeing this issue.
