Latest Message<\/th>\nTitle: Some users may be unable to access or see Excel data in multiple Microsoft 365 services on the web<\/p>\n

User impact: Users may be unable to access or see Excel data in multiple Microsoft 365 services on the web.<\/p>\n

More info: Specific Microsoft 365 services affected are Power BI and SharePoint Online, though any Microsoft 365 service that uses Excel web access may be impacted.<\/p>\n

The impact scenario for Power BI is that some users may be unable to view data when opening imported Excel workbooks in Power BI workspaces. To avoid this issue, users can see the data when opening workbooks in Excel or Excel for the web.<\/p>\n

The impact scenario for SharePoint Online is that some users may be unable to access or view Excel content on SharePoint Online sites because the content is blank and greyed out. To avoid this issue, users can open the Excel file directly without using web parts.<\/p>\n

Current status: Our additional analysis into the compatibility issues that were introduced by the recent change has determined that a fix deployment will be required to remove it and remediate the impact. We’re developing a fix and expect that an estimated timeline for the deployment will be available after our internal validations have confirmed it will remediate the impact. <\/p>\n

Scope of impact: Some users attempting to view or access or see Excel data in multiple Microsoft 365 services on the web may be impacted. This information may be updated as our investigation continues.<\/p>\n

Start time: Thursday, January 29, 2026, at 4:00 PM UTC<\/p>\n

Root cause: A recent deployment in Excel introduced a compatibility issue with multiple Microsoft 365 services that’s preventing the data from populating on the web.<\/p>\n
