So, I have a BES3.6. I am migrating all of my users from Ex2000 to Ex2003. The servers are running concurrently. I know there are issues when the CDO.dll doesn't match...

has anyone run into problems with both versions of exchange?

If you do start seeing issues, just uninstall ESM2K and install ESM2K3 with SP1 and register the CDO.DLL (or I suppose you could do an in-place upgrade; and you may want to unregister the CDO.DLL first).

And if you go to Ex2k3SP1 remember to copy and register the new dll over to the bes server.
