Hi I have an Exchange 2007 Mail Enabled Universal Distribution Group that has: Alias: MarketingUK Email Address: marketing.uk@domain.com Basically, outside contacts email this address and then it then goes to the whole Marketing department. The Marketing manager has now decided that he wants his team to be known as Marketing EMEA, instead of Marketing UK. We need to change the DL address to reflect that, but at the same time previous contacts' emails should not be bounced. Is there any reason why I can't add Marketing.EMEA@domain.com as a secondary SMTP address on the DL? What I'm confused about is: i. What to do about the Alias ii. What point does a Primary SMTP address have on a DL? Many thanks in advance.

The SMTP email address can be anything you like, and you can have as many addresses as you like. The alias doesn't matter. If you change the alias that will only break things internally. Externally it has no effect. As for the primary address - that is used if someone is granted Send As permissions on the group - it will be the address the email leaves as.
