We are currenly running Exchange 2007, but had an Exchange 2003 server running in the domain. We finally removed it, and are having issues with resource scheduling. I have gone through and converted the resources to Room Mailboxes, and set the Automate processing to AutoAccept. I have logged into each of the resources and checked the settings on each, and all seem to be correct based upon all that i see online.
When an user creates a meeting request, and adds the room as a resource, the resource does get booked and the meeting organizer receives an email saying that the meeting was accepted. However, the organizer also receives an email saying that they have incorrectly attempted to reserve a resource by specifying it as an attendee.
I have verified that the room is being added as a resource. We have users on both Outlook 2007 and 2010 and both have that issue.
Any assistance would be appreciated.
