i have 1200 users in 1 active directory. I have 27 e-mail domains on the exchange server. Every user has at least one e-mail address in one of the E-mail domains. I want to add one extra e-mail address from one of the 27 e-mail domains to all users that do not already have an e-mail address in that mail domain. I also want to keep the original E-mail address and i must keep the DEFAULT address to the original one. I only want to add one extra e-mail address (of one of the E-mail domains) to all receipients that do not already have an address in that E-mail domain. I tried the receipient policy in exchange manager, but it does not what i want: When i create a new policy with the SMTP E-mail domain that i want to add, it creates a new address for the users, but when there are users with e-mail addresses with a name before the @ that is different than the user logon name (Ex.: username: "PeterL", has an default e-mail addres "Peter.Long@xxxxxxxxxxxxxx") it creates a new E-mail address PeterL@xxxxxxxxxxxxxx and makes this one the default address. Is there a way to do this in Exchange manager or are there any tools that can add an e-mail address to every user without changing the default address or adding an extra address in the same mail domain? Toine.!
