Question details

Microsoft Office displays incorrect initials or an outdated user name, even when the correct details are configured in the Microsoft account and admin center.

How to Correct Incorrect Office User Names and Initials

Product: Microsoft Office
Device & OS: Windows
Scenario: A user attempts to update their displayed name and initials after a name change, but Office fails to sync the updated information from the account.
Observed behavior: Office applications continue to show the old name and initials due to cached local identity data or local Active Directory synchronization issues.

Before you start

Make sure you have your current Microsoft account credentials available. If you plan to modify the registry, always export a backup of the registry key first to prevent unintended system issues.

Solution 1Recommended

Reset Office Activation State and Sign In

Signing out and resetting the activation state forces Office to clear temporary session data and fetch the updated account details from the server.

Sign out of Office

Open any Office application like Word or Excel, click on 'File' > 'Account', and click the 'Sign Out' button. Close all open Office applications.

Clear Office credentials

Open the Windows Start menu, search for 'Credential Manager', and select 'Windows Credentials'. Remove any saved credentials related to Microsoft Office.

Sign back in

Relaunch an Office application, click 'Sign In', and enter your updated Microsoft account credentials to sync the correct name and initials.

Solution 2

Clear Cached Identity Data in Registry Editor

If a simple sign-out does not work, Office might be relying on deeply cached identity keys in the Windows Registry that need to be manually removed.

Solution 3

Test with a New Windows User Profile

Sometimes a corrupted Windows user profile prevents Office from updating user details properly. Creating a new profile can bypass this conflict.

Frequently Asked Questions

Why won't my Office user name update automatically?

Office applications often cache your identity information locally to speed up login processes. If there is a sync issue with your Microsoft Account or local Active Directory, this cached data prevents the new name from displaying.

Can I manually change my initials in Office settings?

Yes, you can navigate to File > Options > General, and manually edit the 'User name' and 'Initials' fields. However, if your account is managed by an organization or cached tightly, these manual changes might revert upon restarting the application.

Is deleting registry identity keys safe?

Deleting the Office Identity keys is generally safe as long as you only target the specific 'Identities' folder mentioned. Office will automatically recreate these keys the next time you sign in. However, always export a backup of the registry before making changes.
