How to Fix It
Try one or more of the following:
  • If you're a member of the group, you might be registered with an email address other than stapf@zapf.in. Resend your message using the email address where you received a welcome message from the group.
  • Ask the group owner to add stapf@zapf.in as a group member. If you don't know who the group owner is, contact the organization's customer service department for assistance.
  • Ask the group owner to allow people outside their organization to send email to the group.


More Info for Email Admins
Status code: 550 5.7.193

The Microsoft 365 group, info@haw-hamburg.de, is configured to reject messages sent to it from outside its organization -- unless the sender is a guest group member. stapf@zapf.in isn't part of the organization, and it isn't a guest group member.

If you're the group's email admin or owner, check if the sender is a member of the group, but is registered under a different email address. Alternatively, the group owner, or email admin, can add stapf@zapf.in as a guest member of the group.
