03:38 PM		Service Restored Title: Some users may be unable to access or see Excel data in multiple Microsoft 365 services on the web User impact: Users may have been unable to access or see Excel data in multiple Microsoft 365 services on the web. More info: Specific Microsoft 365 services affected were Power BI and SharePoint Online, though any Microsoft 365 service that utilized Excel web access may have been impacted. The impact scenario for Power BI was that some users may have been unable to view data when they opened imported Excel workbooks in Power BI workspaces. To avoid this issue, users could’ve seen the data when they utilized workbooks in Excel or Excel for the web. The impact scenario for SharePoint Online was that some users may have been unable to access or view Excel content on SharePoint Online sites because the content was blank and greyed out. To avoid this issue, users could’ve opened the Excel file directly without using web parts. Final status: We’ve successfully deployed our fix to address this issue and confirmed in our testing environment that this issue is resolved. Scope of impact: Some users who attempted to view or access Excel data in multiple Microsoft 365 services on the web may have been unable to do so. Start time: Thursday, January 29, 2026, at 4:00 PM UTC End time: Saturday, February 14, 2026, at 12:30 AM UTC Root cause: A recent deployment in Excel introduced a compatibility issue with multiple Microsoft 365 services that prevented the data from being populated on the web. Next steps: - We’re reviewing our validation and updating procedures to better detect and prevent issues like this prior to deployment in the future. This is the final update for the event.
