Environment: Two domains with trusts and one exchange 2003 mailbox server. User has two ad accounts. Exchange is apart of the 1st domain and user has a mailbox with full mailbox permissions to 2nd domain. If the user logs on the 1st domain they are able to schedule resources if the user logs on to the 2nd domain they receive the error "The item could not be moved. it was either already moved or deleted, or access was denied. unable to directly book a resource for this meeting" On the shared resource calendar default and anon have author permissions. On the mailbox rights authenticated users inherit read perm. If I uncheck "automatically accept meeting request and process cancellations" the user logged onto the 2nd domain is able to send a meeting with resource, but this is not the desired behavior (we want it auto accepted). Any idea's? thanks,
