Integration: The Final Step in Change Management
The final step in successful change management is the Integration stage. Here’s how to bring everything together. Watch now.
Adding Multiple Email Addresses to a Distribution List in Office 365
The other day I was trying to give several email addresses to a Distribution List in a P1 tenant on Office 365. I wanted one distribution list that acted as the owner of sales@mycompany.com and accounts@mycompany.com. No matter how hard I looked in the Exchange Control Panel, I just couldn’t find the option to do it through the web interface. Maybe it’s there and I missed it… but I found it easier and faster to just do it through Powershell.
For the purposes of this demo, I created a test distribution list (DL). You can see in the screenshot that it only allows you to specify one email address.

Create new Distribution List
Once the DL has been created, there also doesn’t seem to be an option to add new email aliases – you can only see the ones that are already there.
Distribution List Email Options
To add new aliases, we fire up Powershell and connect to Office 365.
With one simple cmdlet, we can add as many email addresses as we want.
PS C:\> Set-DistributionGroup test -emailaddresses @{Add='test@doorstamp.com','test1@doorstamp.com','test2@doorstamp.com'}
Now we can see all the email addresses we added when we take a look at the DL in the Exchange Control Panel.
Distribution List with additional email addresses
Now, what about if we want to remove an email address from a Distribution Group?
