Ever since upgrading to 8.0.1 on the servers, we are getting an increasing number of calls from users who are hundreds or thousands of percent OVER their mailbox size.

In all cases, we find that there's one or more appointments that show up with a negative size.

I'm going to assume this is a bug since it's happening all over the place with more than one post office.

We have not rolled out the 8.0.1 client yet
