Latest Message<\/th>\nTitle: Some users may be unable to load pages with custom apps or webparts in SharePoint Online and get an error<\/p>\n

User impact: Users may have been unable to load pages with custom apps or webparts in SharePoint Online and got an error.<\/p>\n

More info: The following error may have been encountered by users when attempting to load an affected page:<\/p>\n

An error occurred during the compilation of the requested file, or one of its dependencies. ‘Microsoft.SharePoint.IdentityModel.SPAuthFlightController’ does not contain a definition for ‘IsRemoveRedirectWithProofTokenOnSignInPageEnabled’<\/p>\n

Final status: We’ve completed the deployment of our fix and confirmed that impact has been fully resolved for all users.<\/p>\n

Scope of impact: Some users may have been unable to load pages with custom apps or webparts in SharePoint Online and got an error.<\/p>\n

Start time: Tuesday, November 11, 2025, at 12:36 AM UTC<\/p>\n

End time: Monday, November 24, 2025, at 6:38 AM UTC<\/p>\n

Root cause: A recent change intended to update the authentication flow mistakenly removed a necessary authentication component, resulting in impact.<\/p>\n

Next steps:
– We’re reviewing our change testing and validation procedures to identify opportunities to improve impact detection and prevent similar future occurrences.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
