SharePoint: Backend migration for Weather, World Clock, and Events web parts

SharePoint’s Weather, World Clock, and Events web parts will switch from Bing Maps to Azure Maps backend by late April 2026. This automatic migration affects organizations using these web parts and requires allowing atlas.microsoft.com in network settings. No changes to user experience or configuration will occur.
