Frequently Asked Questions

Why does Microsoft Whiteboard say 'No connection' when my internet is working fine?

This error usually indicates a problem with Microsoft's servers, a corrupted application cache, or an underlying bug in the specific app version rather than an issue with your local internet connection.

Can firewall settings cause Microsoft Whiteboard connection errors?

Yes, overly restrictive firewall or antivirus settings can sometimes block the specific ports or domains Microsoft Whiteboard uses to sync data. However, if temporarily disabling them doesn't work, the issue is likely app-related.

Will reinstalling Microsoft Whiteboard delete my saved boards?

No, your whiteboards are synced and tied directly to your Microsoft account. Once you reinstall the app and log back in, your boards will automatically be restored from the cloud.
