The main reason for this issue is saved sign-in details and leftover data stored in folders like %localappdata%\Microsoft\OneAuth and IdentityCache. Other possible reasons include problems with Azure AD device registration or saved login information in the keychain on Mac computers. In this article, we will discuss different ways to solve this error.
1. Sign Out of All Office Applications and Sign In Again
Applications use stored cache to load data faster, and Microsoft’s apps save cached credentials for quicker sign-ins. When multiple accounts from the same organization are active, the app can get confused about which credentials to use. Signing out of all accounts and then signing back in with just the right account clears these cached credentials and resolves conflicts. You can also use the Credential Manager to remove any stored credentials for Microsoft 365 applications:
2. Disconnect Work or School Accounts
Sometimes, having more than one work or school account linked to Windows or Office can cause confusion about which account should be used, leading to sign-in issues. Removing accounts you don’t need helps make sure only the correct one is active.
3. Clear Office License Activation Data
Sometimes, Office license activation files become outdated or corrupted, which can cause errors or sign-in problems. Deleting these files forces Office to refresh your activation data and fix any licensing issues.
4. Use the Microsoft Support and Recovery Assistant (SaRA)
The Microsoft Support and Recovery Assistant (SaRA) is a free tool from Microsoft that can quickly help identify and solve common Office issues, including account and activation problems. SaRA guides you step-by-step and can automatically resolve issues that may be hard to troubleshoot manually.
