What editing a group in Outlook means
A group in Outlook is a saved list of email addresses under one name. When you edit a group, you're changing who's on that list — adding people, removing them, or changing the group's name. You're not changing anything about how Outlook works overall; you're just updating your own contact list so the group stays useful to you.
The steps differ slightly depending on whether you use Outlook on the web, Outlook desktop for Windows, or Outlook for Mac. This guide covers all three, because the location of the edit button is different in each one.
Key Takeaways
- A group is your own saved list of email addresses, stored in your Contacts — editing it only changes your copy, not anyone else's.
- On Outlook web, go to Contacts, find the group, click the three dots, and select Edit Group.
- On Outlook desktop for Windows, right-click the group name in your Contacts folder and choose Edit Group.
- On Outlook for Mac, select the group and use the Edit button in the toolbar at the top of the window.
- You can add people by typing their email address or selecting them from your existing contacts; removing someone means clicking the X next to their name.
Editing a group in Outlook on the web
Open Outlook in your browser and go to your Contacts. Find the group you want to change — groups usually appear near the top of your contact list, with a people icon next to the name. Click on the group name to open it.
Once the group is open, look for three dots (called a menu button) in the top right corner of the group card. Click those three dots, then select Edit Group from the menu that appears. The group will open in edit mode, and you'll see all the current members listed.
To add someone, click the Add Member button or the plus sign. Type the person's name or email address. Outlook will show you matching contacts as you type. Click the person you want to add. To remove someone, find their name in the list and click the X next to it. When you're done making changes, click Save at the bottom of the screen.
Editing a group in Outlook desktop for Windows
Open Outlook and go to your Contacts folder. You can find this by clicking the Contacts icon at the bottom left of the window, or by using the folder list on the left side. Look for your group in the contact list.
Right-click directly on the group name. A menu will appear. Click Edit Group. The group will open in a new window showing all current members. To add a member, click the Add Member button at the top of the window. A dialog box will open where you can type a name or email address, or browse your contacts to find the person. To remove someone, click their name in the list and then click the Remove Member button.
After you've made your changes, click Save and Close at the top of the window. Your changes are saved to your local contact list when ready.
Editing a group in Outlook for Mac
Open Outlook and click the Contacts icon at the bottom of the window. Find your group in the contact list and click it once to select it. Look at the toolbar at the top of the window — you should see an Edit button. Click it.
The group will open in edit mode. You'll see a list of current members. To add someone, click the plus sign button below the member list. Type the person's name or email address in the box that appears, or click the browse button to select from your contacts. To remove someone, click their name in the list and then click the minus sign button.
When you're finished, click the Done button at the bottom right of the window. Your changes save automatically.
Adding and removing members step by step
Adding a member works the same way across all three versions: you provide a name or email address, Outlook searches your contacts, and you confirm the person you want. If the person is already in your contacts, their name will appear as you type. If they're not in your contacts yet, you can still add them by typing their full email address.
Removing a member is faster — you just find their name in the group and click the remove button (usually an X or a minus sign). The person is removed from your group only; they don't receive any notification, and nothing changes on their end. You can always add them back later if you change your mind.
If you're adding multiple people at once, add them one at a time rather than trying to paste a list. Outlook doesn't accept pasted lists in the add member field, so you'll need to enter each address separately or select each person from your contacts.
Common reasons to edit a group
People edit groups most often because a team member has left and needs to be removed, or because a new person has joined and needs to be added. You might also rename a group if its purpose has changed — for example, changing "Q1 Project Team" to "Q2 Project Team" when the project moves to the next quarter.
Another common reason is cleaning up old groups. If you have a group you haven't used in months, you might delete it entirely rather than edit it. To delete a group, right-click it (on desktop) or click the three dots (on web), then select Delete. On Mac, select the group and press Delete on your keyboard.
What happens when you edit a group
When you edit a group, you're only changing your own copy of that list. If you send an email to the group before editing it, everyone on the old list gets the email. If you send an email after editing it, only the new list receives it. No one else sees that you've edited the group, and no one gets notified of the change.
If multiple people have created the same group (for example, "Marketing Team"), editing your version doesn't change anyone else's version. Each person's group is separate. This is why groups are useful for organizing your own email — they're entirely under your control.
Frequently Asked Questions
Can I edit a group that someone else created and sent to me?
No. If someone sent you a group as a contact file, you can import it into your contacts, but you can only edit groups you created yourself. If you need to change a shared group, you'll need to create your own version with the members you want.
What if I can't find the Edit button?
Make sure you're looking at a group, not a single contact. Groups have a people icon next to the name. If you're on Outlook web and don't see the three dots, try clicking directly on the group name first to open it. On desktop, make sure you right-click the group name itself, not just anywhere in the Contacts folder.
Can I add someone to a group if they're not in my contacts?
Yes. Type their email address directly into the add member field. You don't need them to be in your contacts first. Outlook will accept any valid email address.
If I remove someone from a group, do they know?
No. Removing someone from a group sends no notification. They won't know unless you tell them separately, and they'll only notice if they're not included in the next email you send to the group.
Can I edit a group on my phone?
Outlook mobile apps let you view groups and send emails to them, but you can't edit groups from a phone. You'll need to use Outlook on the web or desktop to add or remove members.
