Managing Distribution list senders
In Outlook on the web (https://outlook.office.com/mail/ ) click on the settings gear icon in the top right.
In the search box type in “Distribution” and click on “Distribution groups”.
In the window that pops up it should show groups you are a member of and groups you own. It sometimes takes several moments to load this information. Select the group you want to update from the list of groups you own. If the group is not listed contact IS&S for further assistance. This example will be using the “#Test_Announce” list.
With the group selected click on the pencil icon to open the edit window for that list.
In the new window select “delivery management” to get to the screen that will allow you to add or remove allowed senders.
To add another user click on the + icon
In the screen that pops up select “Default Global Address List” to switch to a list of all users.
Use the search box to find the user that you would like to add and click the + icon to the right of their name.
Click Save in the bottom right to add the user to the allowed sender list.
Click Save in the bottom right again to confirm all changes made to the distribution group.
