How to Fix Office Professional Plus Account Disconnects on Multiple PCs

Product: Microsoft Office Professional Plus 2021

Observed behavior: Office reports that the account cannot be accessed or asks the user to sign in again, although clicking 'Continue' temporarily restores the connection on the affected machine.

Clear Stale Office Credentials in Windows

Removing old or conflicting Microsoft account credentials from Windows can resolve recurring disconnects when switching between multiple PCs.

Windows stores your sign-in details in the Credential Manager. When you use the same Microsoft account across multiple devices, outdated or corrupted cached credentials can cause Office to frequently ask for re-authentication.

Open Credential Manager

Click the Windows 'Start' button, type 'Credential Manager' in the search bar, and select the application from the results.

Access Windows Credentials

In the Credential Manager window, click on the 'Windows Credentials' tab to view your stored login information.

Remove Office Credentials

Scroll down to the 'Generic Credentials' section. Look for any entries starting with 'MicrosoftOffice'. Click the down arrow next to each relevant entry and select 'Remove'.

Restart and Sign In

Restart your computer. Open Excel or Word, click on 'Sign In' at the top right corner, and enter your Microsoft account details to establish a fresh connection.

Clear Stale Office Credentials in Windows

Credential Cleanup Complete: Clearing credentials forces Office to fetch a new authentication token, which often stabilizes the connection across multiple PCs.

Solution 2

Verify Account Licensing Limits

Ensuring your account is not exceeding device limits is crucial, as Office Professional Plus is often restricted to a single PC.

Frequently Asked Questions

Why does Office Professional Plus 2021 ask me to sign in repeatedly on different PCs?

This usually happens due to conflicting credentials in the Windows Credential Manager or because the Microsoft account is being used on more devices than the license agreement permits.

Can I use one Office Professional Plus license on multiple computers?

Typically, Office Professional Plus is a single-PC license or handled via organizational volume licensing. You must check your specific license agreement; using a single-PC personal account on multiple devices will cause activation and account disconnect errors.

Will resetting my local network fix the Office account disconnect issue?

While a network reset can fix general connectivity problems, the 'account cannot be accessed' error in Office is almost always related to credential caching or Microsoft account device limits rather than your local LAN or router configuration.
