Notice Regarding Changes to OneDrive and SharePoint Browser Specifications (MC1150662)

Due to recent changes in web browser specifications, some functions of OneDrive and SharePoint Online may be restricted.

We will provide information about the changes and the actions you need to take, so please review and respond accordingly.

Changes and Impact

Due to specification changes in Chromium-based browsers (such as Google Chrome and Microsoft Edge), restrictions on access to local networks have been strengthened. As a result, when using OneDrive for Web or SharePoint Online, you may see pop-ups asking for "permission to access the local network."

If you do not address this, there is a possibility of performance degradation or the offline functionality becoming unavailable, so please take the following actions.

Operation when a popup is displayed

Please note that this guide does not recommend the same operations uniformly across all sites.
Please ensure that the "Allow Block" operation is carried out properly only for trusted sites.
