How to Fix Microsoft 365 Work or School Sign-In Error 50058
Question details
Users and administrators are unexpectedly logged out of a Microsoft 365 nonprofit account and are unable to sign back in.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Attempting to sign in to a Microsoft 365 work or school account using mobile and desktop applications.
- Observed behavior
- The sign-in process repeatedly cycles on mobile devices, and applications return error code 50058. The user's personal Microsoft account continues to work normally.
Before contacting support, ensure you have your exact error code (50058), request IDs, correlation IDs, and the timestamp of your failed sign-in attempt ready.
Contact Microsoft 365 Phone Support
Because authentication issues require backend support tools unavailable in public forums, administrators must contact Microsoft Support by phone.
Resolving tenant-wide authentication blocks or deep Azure AD issues requires specialized permissions.
Microsoft Support agents have the diagnostic tools necessary to break the sign-in loop and restore access to your nonprofit or business account.
Navigate to the official Microsoft 365 admin support contact info page online.
Locate the Global Customer Service phone numbers specific to your country or region.
Call the support line and provide your nonprofit or organization account details to verify your identity as an administrator.
Gather Error Logs and Troubleshooting Details
Collect necessary diagnostic information to expedite your support request.
Seek Microsoft Authenticator Assistance
If the login loop is specifically tied to the Microsoft Authenticator app, use specialized Q&A forums for targeted help.
Use WPS Office When Microsoft 365 is Unreachable
While waiting for Microsoft support to resolve your organization's authentication issues, you can continue working on your documents, spreadsheets, and presentations offline using WPS Office. It's a free, lightweight alternative that is fully compatible with Microsoft formats.
- 1. Download WPS Office: Visit the official WPS website to download the free office suite installer.
- 2. Install the software: Follow the simple on-screen instructions to install WPS Office on your device.
- 3. Open existing files: Open your locally saved Word, Excel, or PowerPoint files directly in WPS Office to continue working without signing in.
Frequently Asked Questions
What does Microsoft 365 error code 50058 mean?
Error 50058 generally indicates that a silent sign-in attempt failed. It typically occurs when a user's session has expired, the account has been blocked, or the system needs the user to re-authenticate, but a background loop prevents the prompt from displaying correctly.
Can I fix error 50058 without contacting my administrator?
If you are an end-user, you usually cannot fix this yourself. You need to contact your IT administrator so they can reset your session or check Azure Active Directory logs. If the administrator is also locked out, they must contact Microsoft Phone Support.
Why does my personal Microsoft account still work while my work account gives error 50058?
Error 50058 is specific to the enterprise authentication system (Azure AD) used by work, school, or nonprofit organizations. Personal Microsoft accounts use an entirely different authentication infrastructure and are therefore unaffected by organizational tenant errors.
Where can I find the Correlation ID for the sign-in error?
The Correlation ID and Timestamp are usually displayed at the bottom of the sign-in error screen. You may need to click a link that says 'More details' or 'Troubleshooting details' to reveal this information.
