Meeting rooms for certain external users

Question

Hi

I have found the command to allow external users to book a internal meeting room.

it's my understanding that this command will allow any external to book the room if they now the full address.

Set-CalendarProcessing -Identity "<roomname>@<Domain>.com" -ProcessExternalMeetingMessages $true

i want to only allow certain domains too be able to book my rooms.

is it possible to make something like

Set-CalendarProcessing -Identity "<roomname>@<Domain>.com" -ProcessExternalMeetingMessages $true -Allow "@Stuff .com","@centos .com"

if this isn't possible. can i then open for external mail-addresses? and then allowing every single user to book the meeting insteed?

Answer 1

You would have to use a transport rule for to allow those domains

If sent to that room from outside the org to the room, then block Except if from these domains.

I can provide a sample pic if that doesnt make sense.
