Today i was looking for some good scripts for handling room mailboxes. I found these:

new-Mailbox -alias “Meeting Room” -database “Mailbox Database” -name “Meeting-Room” -resourcetype room –userPrincipalName room-meetingroom@exch.local –OU “Resource Mailboxes/Company”

Creates a new Room Mailbox

Set-MailboxCalendarSettings MeetingRoomAlias -AutomateProcessing:AutoAccept

Enables Auto Accept

Set-MailboxCalendarSettings MeetingRoomAlias – AddAdditionalResponse $True
Set-MailboxCalendarSettings MeetingRoomAlias – Additional Response “This is the custom Response”

Sets alternate decline response.
