I've been looking through the technet library and the help information in Exchange Server 2007 but I can't find an answer. Why must mail-enabled contacts have an email address within my organization? For instance lets say I have John Doe and he is a mail enabled contact with an external email of jdoe@externaldomain1.com. Now upon making this mail enabled contact Exchange Server creates an additional email for this user within my domain called jdoe@mydomain.com. Now when I try to delete this added email of jdoe@mydomain.com Exchange automatically re-adds it to the user. Why? What is the logic behind every mail-enabled contact needing to have an email within my domain?

Its default behavior, bcoz the flag "Automatically update the email addresses based on Email Address Policy" is selected by default for all mail contacts. You can uncheck this flag, and then can either remove the email addresses, or just make your external email addresses as primary email address too. You can do this in "EMC->Recipient Configuration--> then select properties of contact and goto Email Addresses tab, and there make this change.

Thanks Laeeq Qazi for the response. Sure enough after unchecking "Automatically update the email addresses based on Email Address Policy" allows the email created in the local domain to be removed. Not sure why the documentation on Mail contacts doesn't mention this. Maybe I just wasn't looking in the correct spot. Anyway thanks again! :)
