Hi all? Last Saturday I began an Upgrade from Exchange 5.5 to Exchange 2K for a client. The server were up to Sp3 on W2K and SP4 on Exchange, everything was running smooth until I insert the Exchange 2K CD for the upgrade. The thing was that the upgrade can not be done because the name of the organization contains invalid characters; the character was an ?&? in the middle of the name. The message told me that I have to change the name of the organization thru the Admin console for Exchange 5.5. I have tried everything to do it, but without success. Can anyone point me in the correct direction to solve my upgrade.? Thanks Darwin O.
