(EV2007 SP1 for Echange)
A while back, I ran a report-only of my top 50 mailboxes, and ran into some "anomolies". Specifically, for certain large mailboxes, the total-number and total-size report fields didn't seem to match with Exchange stats. Also, the number-archived and size-archived fields were in some cases much much less than expected (archive all, all message types, archive deleted).
Looking back at this report, I have noticed that the "Quota Used" column appears to have a maximum of 4gb (4,194,303) for all mailboxes that exceed 4gb. I am NOT using quota based archiving - no size limits on mailboxes. If this is some sort of limit, then this could be coloring the output.
According to Symantec Doc ID# 273162:
Quota Used: Total size of items in the user's mailbox.
So, I'm curious if anyone else has run into this, and knows if this is some reporting limit or an EV setting that I haven't tracked down.
