All, I am out of my mind with trying to stop a forwarder going to an individual. We migrated from 2003 to 2007 last year. We have a mailbox acting as a conference room with members of staff managing it. Anytime a change is made to the calendar of this mailbox, an email goes out to 2 internal addresses. I have checked the forwarder in emc and it is not enabled. I have also ran set-mailbox -identity "mailbox name" -ForwardingAddress $null with no success. I've converted the mailbox to a room resource and back, disabled and enabled, verified permissions in the emc, no luck. My hope is someone out there has an idea on what else I could try as I must be overlooking something.
