Reconnect OneDrive in Microsoft 365 Connected Services

Manually reconnecting your OneDrive account can refresh the service connection and resolve the Copilot and AutoSave synchronization errors.

Often, authentication tokens between Microsoft Office applications and OneDrive can expire or become corrupted. Removing and re-adding the service forces a fresh connection.

Open your Office application

Launch Microsoft Word, Excel, or PowerPoint on your device.

Navigate to Account Settings

Click on 'File' in the top-left corner, then select 'Account' from the left-hand menu.

Add Connected Services

Under the 'Connected Services' section, click on the 'Add Service' dropdown menu.

Select OneDrive

Choose 'Storage' and then select 'OneDrive'. Follow the on-screen prompts to sign in and reconnect your account.

Test AutoSave

Try manually saving your file to OneDrive to verify if the AutoSave toggle and Copilot features are now working.

Frequently Asked Questions

Why does AutoSave fail even when my OneDrive has 1 TB of free space?

AutoSave failures are often caused by a disconnected or expired authentication token between the Office application and OneDrive, rather than a lack of storage space. Reconnecting the service usually resolves this issue.

Are the strangely named folders in my OneDrive a security risk?

Not necessarily. OneDrive sometimes generates folders with localized or unfamiliar text during background syncing or service updates. If this occurs alongside a sync error, it is typically normal system behavior.

Can I use Microsoft Copilot Pro features without saving to OneDrive?

No. Many Copilot Pro features within Microsoft 365 applications require your document to be saved and synced to OneDrive so the AI can securely access, analyze, and process the context of your file.
