Hi all, I have few exchange 5.5 server in my oganization. I removed the user from my remote exchange to main head office exchange. When I deleted the user and create the same user at main exchange server, I got the differnet email ID. When i am trying to change the email ID to the previous one , I am getting the message " this email-address already exists in this organization". Now my problem is that user can not recieve the email on his previous email ID. He has to inform to everone for the new email ID. Do you have any workaround. I already tried directory replicaion between exchanges,but it seems it is not working.
