FYI: Can’t use Exchange Impersonation with GetUserOofSettings, SetUserOofSettings, or GetUserAvailability

I kept forgetting about this so maybe blogging it will help me remember. As this thread confirms – you can’t call GetUserOofSettings, SetUserOofSettings, or GetUserAvailability when using Exchange Impersonation. If you try to do this you’ll get an error that the Service Account is not the mailbox owner.
