How to change your Microsoft 365 email address

As with changing the display name and address, only users with administrator privileges can perform this operation.

Setting your primary email address

If one user has multiple email addresses, one of the email addresses must be set as the primary email address (main address).

Here‘s how to set your primary email address:

1. Go to the Microsoft 365 admin center ( https://admin.microsoft.com/ ) and sign in
2. Click “User”
3. Click “Active Users”

How to use your old email address

If you change a user’s primary email address, the previous email address is retained within Microsoft 365 as a secondary email address.

Reducing old email addresses can cause NDR errors (delivery failures), so it is recommended that you do not delete email addresses even if they are no longer in use, but leave them as they are.

Summary of procedure for setting display name and email address

• For individual plans, you can change your display name and contact information from your Microsoft 365 account page.
• For corporate plans, a user with administrator privileges must change the display name and contact information
• After changing your email address, it is recommended that you keep your old email address as is.

Changing your display name or email address is an operation that occurs frequently, so it’s useful to keep it all in mind.
