Solution 1Recommended

Verify Service Health and Re-sign into Microsoft 365

Because the #CONNECT! error is often caused by Microsoft server outages or authentication glitches, checking server status and refreshing your login is the best first step.

Connected features in Excel require a seamless link to Microsoft's cloud servers. If the servers are down or your session has expired, Excel will trigger this error.

1
Check Service Health

Visit the Microsoft 365 service health dashboard online to verify if there are any ongoing outages affecting Excel or connected services.

2
Sign Out of Microsoft 365

In Excel, click on your profile picture or name at the top right corner, or go to 'File' > 'Account', and select 'Sign out'.

3
Restart Excel

Close all Excel windows completely and reopen the application to clear the temporary session data.

4
Sign Back In

Go back to 'File' > 'Account' and click 'Sign In'. Enter your Microsoft 365 credentials to establish a fresh connection to the server.

Verify Service Health and Re-sign into Microsoft 365
Wait for Resolution: If the Microsoft Service Health dashboard indicates an active outage, you will need to wait for Microsoft to resolve the server issue before the error disappears.
