I have three equipment mailboxes in 2007 Exchange on a 2003 Domain, only one will work. That is when a meeting request is sent to all three boxes (for the purpose of booking a laptop) only one mailbox replies the other two do not. I have tried sending to each of the two mailboxes giving me trouble individually with no luck.
After some searching I found two mailboxes for the other NON working equipment mailboxes in “Disconnected Mailboxes” which was weird so I reconnected them and no change.
Does anyone have any idea as to how I can go about troubleshooting these mailboxes, as I did not and have not setup 2007 equipment mailboxes permissions I am not sure where to start.
