We had 4 student address lists in our EX2003 environment and have since turned off the EX2003 student email server. The lists are blank when we try to access them through Outlook. When we try to edit the address lists in EMC, everything is greyed out. The current recipients filter shows the old student EX2003 server as well.
I realize I will likely have to turn that server back on... but can someone please tell me the steps to get these address lists converted for use by EX2007?
