Exchange 2003 and 2010 coexistence - 2003 decommission

Hi all,

I've inherited an environment and I have some issues with it.
First of all, I have two Exchange Servers. A 2003 and a 2010. The guy who was here previously
migrated all the mailboxes and the public folders too to the 2010 server. I have turned off the 2003 for 3 days
and it seems that everything is working fine without it. Is it safe to uninstall the 2003 in this
case or are there any scripts or tools which I can use to find out if every necessary parameter point to
the new server?

Thanks a lot and kind regards,
Dvijne
