Question details

The user needs to resolve an AADSTS50058 silent sign-in error triggered by Mendeley Cite, which disrupts Office applications and AutoSave functionality.

Product: Microsoft 365 / Mendeley Cite
Device & OS: not provided
Scenario: Attempting to use the Mendeley Cite add-in or working on a document in Microsoft Word when the active session expires or drops.
Observed behavior: A silent sign-in request fails with error AADSTS50058, indicating no active user session, which subsequently interrupts the Microsoft Office sign-in process and disables AutoSave.

Before you start

Ensure you have your Microsoft 365 account credentials handy and a stable internet connection to verify your account status online.

Solution 1Recommended

Verify Microsoft 365 Account Status and Web Access

Check if the issue is isolated to the desktop application by testing your account authentication via the Microsoft 365 web portal.

The AADSTS50058 error often occurs when the desktop application loses its authentication token. Verifying your login online helps determine if the issue is with your account or the local Office installation.

Access the Office Portal

Open your web browser and navigate to https://portal.office.com.

Sign In to Your Account

Enter your Microsoft 365 credentials to log in to your dashboard.

Test Web Applications

Launch Word Online from the portal and check if you can open and edit documents without encountering the AADSTS50058 error.

Verify License

Navigate to 'View account' > 'Subscriptions' to verify that your Microsoft 365 license is active and properly assigned.

Tip: If web access works perfectly, the issue is likely a local cache problem with your desktop Office application.

Solution 2

Gather Diagnostic Details and Isolate the Device

If the error persists, capture specific diagnostic codes and test on a different computer to help Microsoft or your IT admin investigate the issue.

Frequently Asked Questions

What does the AADSTS50058 error mean?

The AADSTS50058 error indicates that an application (like Mendeley Cite) attempted a silent sign-in, but the user is not actively logged in or the session has expired, preventing the authentication token from being issued.

Why does the AADSTS50058 error disable AutoSave in Word?

AutoSave requires an active, authenticated connection to OneDrive or SharePoint. When your session drops and triggers this sign-in error, Office loses its cloud connection and cannot sync changes automatically.

How do I find the Correlation ID for this error?

The Correlation ID is usually displayed at the very bottom of the error dialog box, or you can find it by clicking 'More details' on the Microsoft sign-in prompt.

Does Mendeley Cite require an active Microsoft 365 subscription?

Yes, to use the modern Mendeley Cite add-in fully integrated within the desktop version of Microsoft Word, an active, authenticated, and licensed Microsoft 365 account is required.
