Well, I'm waiting on a call back from Microsoft Tech Support, but they are claiming a 4 to 8 hour call back time for Exchange right now, their a little swamped it appears. Seems to have something to do with something called DST??? Anyways, I ran the msextmz tool on my mail stores lastnight, it ran successfully on all mailboxes, except for one issue. I neglected to set the Application Event Log on the workstation to overwrite, so it filled up after 500 - 600 users. What this caused was the update tool to successfully update the calendars, but the workstation to consider it a failure, so the updated meeting requests were never sent out. SO set the event log properly and just run it again fight? Nope, it's done with it's updating it has nothing to do, so will send out no meeting requests. I have the list of close to 3000 users that it didn't send those requests out for, can anyone think of a way to force those requests to be sent out from those 3000 users?
