As an owner of a Microsoft 365 distribution list (DL), you can add or remove members without needing IT support. This guide explains how to manage group membership through Outlook on the web.

Step 1 – Sign in to Outlook on the Web

1. Open your browser and go to
   https://outlook.office.com

2. Sign in with your Microsoft 365 work account.

Step 2 – Open Distribution Group Settings

1. Click the ⚙️ Settings cog (top right).

2. In the left-hand menu, choose General → Distribution groups.

3. You’ll see a message saying: “To manage distribution groups, visit this portal.”

4. Click the link to open the Distribution Groups portal.

Step 3 – Find the Group You Own

• The portal will display two tabs:

  • Groups I belong to

  • Groups I own

• Click on Groups I own.

• Select the distribution list you want to manage.

Step 4 – Manage Owners and Members

• A side panel will open for the selected group.

• From here you can:

  • Add members → search for a name or email, select the user, and click Add.

  • Remove members → select the user and click Remove.

  • Manage owners → add or remove group owners as needed.

Step 5 – Save Changes

• Confirm your updates before closing the panel.
