I discovered that the admin mailbox has 1.5 Million messages in it, nearly all NDRs. I'm trying to exmerge the mailbox using the archive option through the Exmerge gui. Exmerge tells me that this will require 8gb of disk space. The first time I ran it it cranked away and I was able to see the pst growing. After 30 minutes is stopped growing at 215MB. I let it run for another hour and it didn't get bigger so I stopped the process.
I then started exmerge again on ourt new Ex 2003 server and it's been running for 5 hours, but only created a pst of 237MB.
My questions are:
1) Does anyone know of any limitations with Exmerge that would cause this behavior?
2) Does anyone know of a better way to empty this mailbox of all contents? What might be the impact of deleting the mailbox and recreating it?
We have a 5.5 and a 2003 server. 5.5 is where the bulk of the mailboxes exist, including this admin mailbox.
Thanks for any help
