I have a strange situation in my mail environment,
I tried to block meeting rooms to reserve another meeting room,
So I created a dynamic list with all the meeting rooms in it, that I put in rejected senders in Mail Flow Settings,Message Delivery Restrictions,
The problem is that I see that the mail is not arriving ( No message of Tentative,) but in the calendar the items still creates a slot with tentative,
Someone has a solution, how can I really block this DL and the meeting will not appear..?
Thank you in advance, for the solution,
Hendrik
