Im running ex2003 and ex2010 in a co-existing env. I recently upgraded my EAP and Address lists to be compatible with ex2010. Now Im having issues with ex2003 resource mailboxes . When a user sets up a meeting and invites the resource as a resource the mail gets to the mailbox but it does not auto accept/decline it. It does not process it at all.
The resource mailbox and users are all on exch 2003. Im not sure how ex2010 would affect this? The only changes I’ve made was upgrading the EAP and AL etc.
