Some users may be unable to access or see Excel data in multiple Microsoft 365 services on the web
Start Time: 2026-01-30 01:00(JST)
Last Update: 2026-02-14 11:50(JST)
Status: Service Restored
Affected Service: Microsoft 365 suite
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.
