How can I administratively cancel guest invitations?

When a user in MS 365 sends a guest invitation, it apparently never expires.   The awesome Matt Zorich posted a Sentinel query to enumerate guests who didn't RSVP here:

My question is: Now what?  How can I administratively delete stale invitations that are out there?

  • You cannot delete the stale invitations that are out there. Once you delete the guests who did not RSVP the invitations that are out there will be of no use. They will not be able to access the tenant it there is no pending #EXT# account.
    Hope this answers your question.

      So whack the Guest accounts themselves if they're a concern. Makes sense, thanks!
