If this isn’t a once-in-a-blue-moon task that needs mentioning – I don’t know what is! How often do you get a new domain or rebrand your company? After Finance have done their bit and Marketing have diddled around with PR mumbo jumbo, the real work down in the IT department is to tell your Exchange server to start accepting email for a new domain. Well, it’s quite simple:

Open Exchange Sytem Manager
Goto Recipients -> Recipient Policies
Right-click / Properties on your default policy
Look under the “E-Mail Addresses (Policy)” tab

In here, you’ll have a list of domains that your exchange box accepts and sends email for. The SMTP entry in bold is your primary domain. From here, you can either editing an existing domain – or create a new SMTP ‘address’. Be aware that setting a new domain to primary (especially in large organisations) will take some time! (as it’s got to go through every AD account and set the primary domain)

Did you find this hint useful? Are you looking to learn more about Exchange? Well, here’s a few books that I’ve found useful – have a goosie!
