I have a scenario where, when a user books a resource mailbox by adding it to a meeting invitation, I need to enforce booking another resource mailbox too; the underlying logic is something like "when you book this equipment, you must also book the room where it resides".

I'd like this to be automated, instead of requiring the users to add both resources to their meeting invitation.

How can this be implemented, if it can be implemented at all?

The resource mailboxes auto-accept meeting requests if they receive them.

You could create a transport rule to add the another resource mailbox to the 'TO'box: enter image description here

If you want the resource mailbox to accept meeting request automatically, you could run below command to configure it:

Set-CalendarProcessing -Identity "resource mailbox" -AutomateProcessing AutoAccept

For more details: Set-CalendarProcessing

  • Was thinking about that, I'll test and confirm. Automated request accepting is already enabled. – Massimo Nov 13 '20 at 08:49
