We can migrate meetings in just fine. Unfortunately, our migration of resources is running in a somewhat more difficult fashion. I have finally gotten us to the point that I can migrate a meeting in to someone's calendar with a resource as one of the attendees (so the resource gets booked) but the resource doesn't see it until the owner clicks on the message and choses "save", which of course sends a message to the meeting room and books it.

This is all very well and good, but I can't go through 500 users' accounts as part of the migration and click "save" on every single meeting. Is there a command line tool that I can use for this? I'd expect it'd be something in zmmailbox, but I'm stumped as to what.

Alternately, is there a useful tool where I can import an ICS file and have it auto-propagate to two users' calendars at once? (The resource and the organizer.)
