I want to now what is the thumb rule to limit who can send end messages to Outlook 365 Distribution groups, lets say you have a more than 50 such DGs which you want to be restricted & limited from sending anyone messages to these groups except explicitly what admin defined in the "Only senders in the following list" in EAC or admin center of 0365.
That's up to you, requirements will differ across organizations and scenarios. It's usually a good idea to restrict the "All users" type of groups, but really it is up to you. We have the controls, use them as necessary.
I totally agree with you that the requirements differ across organizations and scenarios therefore its upto us however i was looking if their is any best recommendation approach or any documentation reference on when & how these controls can be applied based upon given a case case.
Dear Vasil, I am waiting if you can share any best recommendation approach or any MS documentation reference on when & how these controls can be applied based upon given a case case.
