I am migrating users and resources from Ex2007 to Ex2013. I have several different mailboxes on 2007 that are set up as "users", but they are really more of a shared resource Calendar, for departments to use for "time off" or departmental to do lists. Some of them automatically accept meeting requests, but others want to have approval go through a delegate. My dilemma is these calendar mailboxes aren't really equipment or rooms, but I may want them to be approved through a delegate like a resource. If I keep them as a user, I don't have the visibility of seeing any delegates or setting how far ahead calendar items can be reserved, but items can be double booked which is good in terms of being used as a "time off" calendar. In 2007 we administer them by logging into the account as the mailbox and configuring them that way.
I am also making this migration with an eye towards moving to Office365, hosted Exchange, so if I have a lot of "user" accounts that are essentially calendar resources, is that going to be a license?
Thanks.
Sally
