Add an Alias to a Distribution Group in Exchange Online (Office365), and Removing one…

Looking back to BPOS, the only way to add an alias to a distribution group, was by using DirSync, as described here:

With the arrival of Office365, and Exchange Online, time to see if it is possible now to have one distribution group with multiple email aliasses, even without using DirSync.

Goal = have a distribution group, with 3 email addresses:,, and

First I will create the new distribution group, using the Exchange Control Panel. I sign into OWA, and from there click on Options, and select to manage My Organization, and from there I create a new distribution group called Sales:




Now time to add the two other addresses…

Option 1. Use the Exchange Control Panel


When selecting the distribution group Sales, and clicking on Details, I can see there is currently one e-mail address, and no Add button:



But when going to the General options, I can see that I can change the e-mailaddress of the group, and that the existing addresses will be kept!


So I enter Info in the E-Mail address, and press Save:


When checking the E-Mail Options, I can see there are now two e-mail addresses for my distribution group:


But no option to remove any of these…

Option 2. Using the Exchange Management Shell

Easy Smile After connecting to Exchange Online, I will use a variable to add the e-mail address of to the distribution group.

PS C:\Users\ilse> $sales = Get-DistributionGroup sales
PS C:\Users\ilse> $sales.EmailAddresses
PS C:\Users\ilse> $sales.EmailAddresses += ""
PS C:\Users\ilse> $sales.EmailAddresses
PS C:\Users\ilse> Set-DistributionGroup -Identity Sales -EmailAddresses $sales.EmailAddresses
PS C:\Users\ilse> Get-DistributionGroup sales

Name                    DisplayName             GroupType               PrimarySmtpAddress
----                    -----------             ---------               ------------------
Sales                   Sales                   Universal               Info@Sir.onmicrosof...

PS C:\Users\ilse> Get-DistributionGroup sales | fl *emailad*

EmailAddresses            : {,,}
EmailAddressPolicyEnabled : False
WindowsEmailAddress       :

Check via ECP, and it’s done Smile


Using the Shell, it’s different to remove an e-mail address:

PS C:\Users\ilvancri> Get-DistributionGroup sales | fl *emailad*

EmailAddresses            : {,,}
EmailAddressPolicyEnabled : False
WindowsEmailAddress       :

PS C:\Users\ilvancri> Set-DistributionGroup -Identity Sales -EmailAddresses '',''
PS C:\Users\ilvancri> Get-DistributionGroup sales | fl *emailad*

EmailAddresses            : {,}
EmailAddressPolicyEnabled : False
WindowsEmailAddress       :

A check in ECP reveals the e-mail address is gone…


Option 3. Using the Exchange Management Console

As blogged before ( it is possible to install the Exchange Management Console, and use it to connect to your Exchange Online environment, even if you do not have a Hybrid setup with an Exchange On Premises.

Using the Exchange Management Console, you can go to the properties of your distribution group, and add/remove e-mail addresses as you need:





Exchange rocks!
