**How to Change a User’s Name While Keeping the Same Email ID in Microsoft 365**

In Microsoft 365, you can update a user’s display name, first name, or last name without changing their email address. This is useful when:

- A user gets married and changes their last name
- A spelling correction is needed
- You want a new display name but keep the same login/email

This guide explains how to update the user’s name safely.

** What Stays the Same?**

When you change the user’s name:

| Item | Changes? |
| --- | --- |
| Display Name | ✔️ Yes |
| First/Last Name | ✔️ Yes |
| Login Email (UPN) | ❌ No (unless you choose to change it) |
| Primary Email Address | ❌ No |
| Mailbox Data | ❌ No |

1. Change User’s Name in Microsoft 365 Admin Center

**Steps:**

1. Sign in to Microsoft 365 Admin Center 
[https://admin.microsoft.com](https://admin.microsoft.com/)
2. Go to Users → Active Users
3. Click the user whose name you want to change
4. Under Account, click Manage username and email
5. Update:
6. Do NOT change the username/email if you want the same email ID
7. Click Save Changes

**The user’s name will update across Outlook, Teams, SharePoint, and all Microsoft 365 apps.**

1. (Optional) Update Display Name in Exchange Admin Center

**Sometimes Outlook still shows the old name. To fix this:**

1. Go to Exchange Admin Center 
https://admin.exchange.microsoft.com [(admin.exchange.microsoft.com in Bing)](https://www.bing.com/search?q=%22https%3A%2F%2Fadmin.exchange.microsoft.com%2F%22)
2. Go to Recipients → Mailboxes
3. Select the user
4. Click Edit under Mailbox Settings
5. Update the Display Name
6. Save changes

**This ensures the new name appears in the Global Address List (GAL).**

1. Force Address Book Update (Optional)

Outlook may take up to 24 hours to refresh.
To speed it up:

- Restart Outlook
- Clear Offline Address Book (OAB) cache
- Sign out and sign in again

Example Scenario

Old Name: Mohammed Imthiyaz
New Name: Muhammed Imthiyaz
Email: stays the same → imthiyaz@domain.com

Only the name changes — the email ID remains unchanged.
