Solved

You don't have permission to sent to

Hi,

When we book a room, the message "You don't have permission to sent to " is showing, and we got the undeliverable bounce back message if sending it.

How to solve this issue? Need help!

Thanks in advance!

This is basically the "delivery restrictions" feature you can configure for any type of mailbox. Someone configured a list of people that are not allowed to send messages, or similarly, a list of people that are allowed and everyone else is blocked. You can confirm this via:

Get-Mailbox roomname | fl accept*,reject*,RequireSenderAuthenticationEnabled

  Hi Vasil,
  
  Thank you for your help! Yes, it is configured to only allow a group of users to book the room.

Are the mailboxes on-premises, in Office 365 or is it a hybrid with one on-premises and the other in Office 365?
