Thanks for the quick Answer. Good tool, if more customization would be possible, we would use it for internal communication.

Hallo Herr Karlov !

Also wenn ich vom persönlichen Outlook an die Gruppenmail sende, kommt die Email an.
Wenn ich von einem Externen Dienst sende (googlemail ) kommt die Email nicht an, mit beschriebener Fehlermeldung.

Ich hab nun auch einen anderen externen anbieter probiert eine "gmx.de" mail...

hier kommt die Email auch nicht an mit selbiger Fehlermeldung:
SMTP error from remote server for RCPT TO command, host: mx01.schlund.de (217.72.192.67) reason: 550 Requested action not taken: mailbox unavailable

Liebsten Dank....

Hello Ms. M, thanks for coming into forums. I'm also a user like you and I'll be more than happy to help you to the best of my knowledge.

Yes, you can check which policy was applied to a user in Microsoft Defender for Cloud Apps by reviewing the audit logs.

To access the audit logs, follow these steps:

-Go to the Microsoft 365 security center.
-Click on the "Threat management" section, and then click on "Audit log search".
-In the "Audit log search" page, you can select "Cloud App Security" as the source and then specify the date range and user account to search for events related to Defender for Cloud Apps.
-Once the events are displayed, you can look for events related to "File upload blocked" or "Policy applied". These events will include information on which policy was triggered and applied.

You can also filter the events by policy name to quickly find the specific policy that was triggered.

Hope this info helps. Feel free to let us know.

Warm Regards,
Myk
