We've been having some issues with our resources not auto-accepting invites, and our Exchange 2007 host has been working his way steadily through fixes with no luck... However, we've now got an interesting situation in which if you select yourself as an invitee before selecting a resource, the meeting would auto-accept for yourself and show up as tentative for the resource, but if you select the resource before selecting yourself as an invitee, the resource auto-accepts and the invitee has it show up as tentative... Is this something we're missing in Exchange settings? Auto accept for first selected item after clicking the "To" button only?

Always specify your version and service pack of Exchange, and when clients (e.g., Outlook) are involved, the version of those as well.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."
