Open the distribution list you want to change

In Outlook, a distribution list is a group of email addresses saved under one name. To edit it, you first need to find it. The steps differ slightly depending on whether you use Outlook on the web, Outlook desktop for Windows, or Outlook for Mac.

On Outlook desktop (Windows), go to the Home tab and select People. Find your distribution list in the contacts folder — it will have a small group icon next to its name. Double-click it to open it. On Outlook on the web, select People at the bottom left, then look for the list in your contacts. On Mac, open Contacts from the sidebar and find the list there.

Key Takeaways

  • Distribution lists open from your Contacts or People section, and you edit them by clicking Edit or Edit Group depending on your Outlook version.
  • You can add new members by typing their email address or selecting them from your contacts, and remove members by highlighting them and deleting.
  • Changes save automatically in Outlook on the web, but desktop versions require you to click Save and Close to explore edits.
  • If you cannot edit a list, it may be owned by someone else in your organization — contact that person or your IT department to request changes.

Add or remove members from the list

Once the distribution list is open, you will see the current members listed. To add someone, look for an Add button or a plus icon. In Outlook desktop, click Add Members. Type the person's name or email address, and Outlook will show matching contacts. Click the person you want and they will be added to the list.

To remove someone, click their name in the list to highlight it, then press Delete or click a Remove button. Some versions show an X next to each member — click that to remove them. Make sure you are removing the right person, because this action cannot be undone until you save.

Save your changes

On Outlook desktop (Windows and Mac), click Save and Close after you finish editing. The button is usually at the top of the window. On Outlook on the web, changes save automatically as you make them — you do not need to click anything.

If you do not see a Save button, check whether you are editing the list or just viewing it. Some versions open lists in view-only mode by default. Look for an Edit button at the top of the window and click it first.

Edit the list name or description

You can change the name of your distribution list and add a description so people know what it is for. In Outlook desktop, the name field is at the top of the list window. Click in it and type a new name. Some versions also have a Notes or Description field where you can add details about the list's purpose.

On Outlook on the web, click the list name at the top to edit it. The description field may appear below the name field. After you change either one, save your changes.

Understand permissions and ownership

If you created the distribution list, you own it and can edit it freely. If someone else created it, you may not have permission to change it. Outlook will show an error message if you try to edit a list you do not own — the message usually says something like "You do not have permission to edit this item."

In a work environment, distribution lists are sometimes managed by your IT department or by a specific person in your organization. If you need to change a list you do not own, contact the person who created it or your IT help desk and ask them to make the change. They can add you as an owner if the change is permanent.

Manage distribution lists in Outlook on the web versus desktop

Outlook on the web and Outlook desktop handle distribution lists slightly differently. On the web, you see all your lists in one place and edits happen when ready. On desktop, lists are stored locally on your computer unless you are using a shared mailbox or Exchange account, in which case they may be stored on your organization's server.

If you edit a list on desktop and the changes do not appear on the web, or vice versa, your lists may not be syncing. Check your account settings to make sure both versions are connected to the same email account. If you use multiple devices, edit the list on the device where you use it most often.

Troubleshoot common editing problems

If you cannot find the Edit button, make sure you have the list open and not just selected. Double-click the list name to open it fully. If the list opens but appears grayed out or locked, you may not have permission to edit it — check with the list owner.

If you add someone to the list but they do not receive emails sent to the list, make sure you saved your changes. Also check that you typed their email address correctly. If the person is in your organization and you selected them from contacts, Outlook should have filled in the correct address automatically.

Frequently Asked Questions

Can I edit a distribution list that someone else created?

No, unless the owner gave you permission. Contact the person who created the list or your IT department and ask them to add you as an owner or make the change for you. They can grant you editing rights if needed.

Do changes to a distribution list happen right away?

On Outlook on the web, yes — changes are when ready. On Outlook desktop, you must click Save and Close for changes to take effect. After you save, the next email sent to the list will include the updated members.

What happens if I delete someone from a distribution list by mistake?

If you have not saved yet, press Ctrl+Z (or Cmd+Z on Mac) to undo. If you already saved, open the list again and add the person back. There is no recovery option once you save, so double-check before closing.

Can I create a distribution list that includes other distribution lists?

Yes. When you add members, you can select another distribution list just like you would select a person. This is useful for combining teams or departments into one larger group.

Why does my distribution list not appear in my contacts?

Check that you are looking in the right folder. In Outlook desktop, distribution lists appear in the Contacts folder under People. On the web, they appear in the Contacts section. If you still cannot find it, search for the list name using the search box.
