Frequently Asked Questions

Why does Excel for the web keep changing my dates to US format?

This is currently a known bug in Microsoft Excel for the web where regional date settings are overridden by the US format. Microsoft's development team is actively investigating this server-side issue, and it usually resolves once they patch the cloud environment.

Why am I getting an Access Denied error on Microsoft Support with an active subscription?

The Access Denied error is typically caused by temporary Microsoft server issues, outdated browser cache, or network configuration problems blocking the authentication of your Microsoft 365 subscription. Trying a different browser or network often resolves it temporarily.

How can I change the regional format settings in Excel for the web?

You can normally change this by going to File > Options > Regional Format Settings in Excel for the web. However, if the known formatting bug is active, these settings may temporarily fail to apply correctly until the server issue is fixed.
