Before I open a ticket with Microsoft, I though I would run this by everyone here first. I currently have a Unity 3.1.5 (Voicemail Only) with failover. I have over 3000 users on it. the other day my Unitys stopped working, and I was able to trace it back to my Exchange 2000 Server. It appears that the MTAData directory have over 100GB of data in it. I managed to clean it out and have since reinstall the SP3 roll-up patch from Microsoft. I have also run the MTACheck utility and it shows no errors. The drive is still filing up. I am getting about 40 new files every minute.
Has anyone seen this before, or have a direction that I should go in. I will do some more snooping around, but I think in the next couple of hours I will be giving Microsoft a call.
