Question details

The user needs to access OneDrive files from a second university account using a different domain, while already signed in to Office with their primary university account.

How to Fix Microsoft 365 Error When Using Two Accounts from the Same Organization

Product: Microsoft 365
Device & OS: Windows
Scenario: Attempting to open files from a secondary educational Microsoft 365 account on the same device.
Observed behavior: An error occurs preventing the user from opening files stored in the second account's OneDrive due to conflicting credentials.

Before you start

Ensure all your important files in OneDrive are fully synchronized or locally backed up before clearing any credentials to prevent accidental data loss.

Solution 1Recommended

Clear Cached Microsoft 365 Credentials and Reconnect Accounts

Removing outdated or conflicting cached credentials forces Microsoft 365 to freshly authenticate both of your education accounts, resolving cross-domain access errors.

When using multiple accounts from the same organization, Microsoft Office often defaults to the cached login tokens of the first account. Manually clearing these stored tokens from your system's credential manager clears the conflict.

Close all Office applications

Save your work and completely close all Microsoft 365 apps, including Word, Excel, PowerPoint, and the OneDrive sync client, to prevent them from recreating credentials while you work.

Open Windows Credential Manager

Press the Windows key on your keyboard, type 'Credential Manager' into the search bar, and press Enter to launch the utility.

Remove cached Microsoft Office credentials

Click on 'Windows Credentials' and scroll down to the 'Generic Credentials' section. Click on any entries that start with 'MicrosoftOffice16' or 'OneDrive' and select 'Remove'.

Re-sign into both accounts

Open a Microsoft 365 application (such as Word). Sign in with your primary education account first, then add your secondary account to verify you can now access files from the second OneDrive location.

Clear Cached Microsoft 365 Credentials and Reconnect Accounts

Verify Account Permissions: Also verify that your second account has the correct permissions to access the specific files and check if your university IT policy explicitly permits multi-account sign-in on a single device.

Frequently Asked Questions

Why does Microsoft Office conflict when using two accounts from the same university?

Office caches credentials to keep you signed in smoothly. When you try to access resources from a second account on a different domain but within the same organizational tenant, the system may get confused by the stored tokens of the primary account, resulting in an access error.

Will removing Windows credentials delete my downloaded OneDrive files?

No. Deleting cached entries in the Windows Credential Manager only removes your saved passwords, forcing the applications to prompt you to log in again. Your actual files stored locally or in the cloud remain completely untouched.

What if the error persists after clearing cached credentials?

If the issue continues, contact your university IT department. Some organizations enforce strict device management and security policies that intentionally prevent multiple educational accounts from being active on the same device at the same time.
