Solution 1Recommended

Clear Saved Credentials and Verify Your Subscription

Removing outdated login data from Windows and verifying your active subscription online can resolve conflicting sign-in data blocking the connection.

Often, previous or corrupted login tokens get cached in your system. Clearing them forces Office to establish a fresh connection to Microsoft's servers.

1
Verify your subscription

Open a web browser, navigate to account.microsoft.com/services, and sign in to confirm that your Office 365 subscription is active and assigned to your account.

2
Close Office applications

Ensure all Microsoft Office applications, such as Word, Excel, and PowerPoint, are completely closed.

3
Open Credential Manager

Click the Windows Start menu, type 'Credential Manager' into the search bar, and press Enter to open the utility.

4
Remove Office credentials

Click on 'Windows Credentials'. Scroll down to the 'Generic Credentials' section, locate any entries starting with 'MicrosoftOffice', click on them, and select 'Remove'.

5
Restart and sign in

Restart your computer, launch an Office application, and try signing in again with your verified Microsoft account.

Frequently Asked Questions

Why does Office 365 say 'We are unable to connect right now' when my internet works perfectly?

This error is typically caused by outdated or conflicting login data cached in the Windows Credential Manager, incorrect system date and time settings, or network proxies blocking Microsoft's background authentication servers.

Does Office 365 require a constant internet connection to work?

No, a continuous internet connection is not required. However, Office 365 subscription versions do require you to connect to the internet and sign in periodically (usually every 30 days) so Microsoft can verify your active license status.

Can reinstalling Office 365 fix the connection and sign-in error?

Reinstalling Office usually does not resolve this specific sign-in error because corrupted credentials, proxy configurations, and network settings remain on your system even after the software is uninstalled. Clearing your saved credentials is a much more effective solution.
