As the Office 365 admin, you may need to change the user name for someone in your organization, if, for example, someone gets married and their last name changes.
This topic explains how to quickly change a user name and calls out a few things to keep in mind so your users can continue to connect their accounts to Outlook, SharePoint, and Lync on their computers and mobile devices.
What do you want to do?
Change a user name
Use this procedure to change a user name and email address.
- Go to Admin > Office 365 > Users and groups.
- On the Active users page, select the user you want to edit, and click Edit .
- Click the Details tabs, and change the user name.
- Complete your changes, and then click Save.
- Let the person know what their new user ID is. They’ll need it to sign in.
NOTE: It might take up to 24 hours for this change to take effect across all services. When the change has taken effect, the user will be prompted to sign in with their updated user ID. They’ll also have to use their new user name when signing into the Office 365 Portal.

What else should your users know
Changing the user name triggers a re-provisioning of the user in Lync Online. If your users are on Lync Online, they will have to reschedule any Lync Online meetings, and tell their external contacts to update the old contact.
If the user has changed their password as well as their user name, they will be prompted to enter the new password on their mobile device on the next sync.
