I have 700 users with an invalid homemta entry in AD. This was probably caused by a failed first attempt to bring in Exchange 2003 several months ago OR a failed uninstall of one of the 5.5 servers. (WHAT A MESS)
I followed the Exchange setups /removeorg documentation to remove the original 2k3 install but it seems to have 'missed' the whacked MTA entries.
NOTE: If I copy a valid homemta to a user account, mail flows perfectly well between 5.5 and 2k3 and back.
Is there anyway to 'bulk' copy the correct MTA into these users?
OR BETTER YET.....
Is there anyway to get 5.5 to tell the ADC what the correct MTA entry should be?
