How to Resolve Microsoft 365 Account and License Conflicts

Product: Microsoft 365
Device & OS: not provided
Scenario: Signing into Microsoft 365 desktop applications using a Family subscription account.
Observed behavior: The user receives username errors or error 50058 when opening Word and PowerPoint, caused by conflicts with other work, school, or personal accounts.

Before you start

Ensure you have the correct Microsoft account credentials associated with your Microsoft 365 Family subscription on hand before attempting to clear existing system credentials.

Solution 1Recommended

Clear Account Credentials and Reinstall Microsoft 365

Removing obsolete account entries and reinstalling the suite from the correct Microsoft account resolves most system-level license conflict errors like 50058.

Conflicting licenses often occur when old work, school, or personal accounts remain cached in your operating system. A clean installation coupled with credential clearing ensures your apps authenticate using your active Family subscription.

Remove conflicting accounts from OS settings

Navigate to your computer's 'Settings', select 'Accounts', and click on 'Access work or school' (or 'Email & accounts'). Disconnect any accounts that are not associated with your current Microsoft 365 Family subscription.

Clear cached credentials

Open the 'Credential Manager' from your system search, go to 'Windows Credentials', and remove any saved credentials that begin with 'MicrosoftOffice'.

Uninstall existing Office apps

Go to 'Control Panel' > 'Programs and Features', select your current Microsoft Office or Microsoft 365 installation, and click 'Uninstall'.

Reinstall from the correct account

Open a web browser, log in to your Microsoft account dashboard associated with the Family subscription, and download the Microsoft 365 installer.

Sign in to desktop apps

Launch Word or PowerPoint and sign in strictly using the Microsoft account tied to your Family subscription to activate the license.

Important Note: If you continue to experience error 50058 after these steps, you may need to use the official Microsoft Support and Recovery Assistant tool to perform a deeper system clean-up.

Solution 2

Sign Out of All Accounts Within Office Apps

Manually signing out of all connected accounts directly from the Word or PowerPoint interface can sometimes force the application to prompt for a fresh, correct login.

Frequently Asked Questions

What causes error 50058 in Microsoft 365?

Error 50058 typically occurs when there is a conflict between multiple Microsoft accounts (such as a mix of work, school, and personal accounts) trying to authenticate the license on your device simultaneously.

Why can I sign into OneDrive but not Word or PowerPoint?

OneDrive and Teams often handle authentication independently or via web tokens. In contrast, desktop applications like Word and PowerPoint rely on deeper system-level licensing credentials, which may fail if there are conflicting profiles saved on your operating system.

Will uninstalling Microsoft 365 delete my files?

No, uninstalling the Microsoft 365 desktop applications only removes the software from your computer. Your personal documents and files saved locally or on your OneDrive remain entirely safe.

How do I clear cached Microsoft credentials on Windows?

You can clear cached credentials by opening the Start menu, searching for 'Credential Manager', navigating to 'Windows Credentials', and removing any entries that start with 'MicrosoftOffice'.
