How to Fix Excel Hanging When Closing Due to OneDrive Sync
Product
Microsoft Excel
Device & OS
not provided
Scenario
Closing locally saved Excel files while OneDrive background synchronization is active.
Observed behavior
Excel freezes during the closing process, often due to account conflicts between Office and OneDrive, file permissions, or failed change merging.
Before you start

Verify that your local network connection is stable, and temporarily pause your OneDrive synchronization to prevent data loss while troubleshooting.

Solution 1Recommended

Verify and Align Connected Office Accounts

Ensure that Excel, OneDrive, and SharePoint are all using the exact same work or school account to prevent synchronization conflicts.

Conflicting accounts are the most common reason Excel struggles to merge changes or release file locks upon closing. Aligning these credentials resolves background authentication issues.

1
Open Excel Account Settings

Launch Microsoft Excel and navigate to the 'File' menu, then click on 'Account' at the bottom left.

2
Check Connected Services

Under 'User Information' and 'Connected Services', verify the email address used for Office, OneDrive, and SharePoint.

3
Sign Out and Reconnect

If the accounts differ, click 'Sign Out' for all accounts. Restart Excel, then sign back in using a single, unified work or school account.

Verify and Align Connected Office Accounts
Account Alignment: Using a unified account across all Microsoft 365 services ensures smooth synchronization and prevents file locking issues.

Frequently Asked Questions

Why does Excel only freeze when I am closing the file?

When you close a file, Excel attempts to finalize changes, release local file locks, and trigger OneDrive to upload the latest version. If there is an account conflict or network delay, this handshake process hangs the application.

How can I check if OneDrive is the actual cause of Excel hanging?

You can isolate the issue by clicking the OneDrive cloud icon in your taskbar, selecting the gear icon, and clicking 'Pause syncing'. If Excel closes normally while syncing is paused, OneDrive is the root cause.

Does this issue happen with all versions of Microsoft Office?

This synchronization freezing issue is most commonly reported in Office 2019 and Microsoft 365 enterprise environments where strict SharePoint permissions and business accounts interact.
