1 Mirrored Mailboxes!!

[Simon]

Hi everyone

This is really weird. We have recently installed a second exchange server on
our network. I have since moved my mailbox over to the new server no problem.
I have successfully connected to the mailbox on the server through Outlook.
However when i'm in Outlook i seem to have a mirrored mailbox!! Why is this?
How do i get rid of the mirrorred mailbox, i only want one!!!

Thanks

Simon
