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 be unable to load pages with custom apps or webparts in SharePoint Online and get an error.<\/p>\n

More info: The following error may be 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

Current status: The deployment of the fix is nearing completion, and we\u2019ve confirmed that some affected users are already experiencing impact resolution. We\u2019ll continue monitoring the deployment to ensure the issue is fully resolved for all affected users by our next scheduled update. <\/p>\n

Scope of impact: Some users may be unable to load pages with custom apps or webparts in SharePoint Online and get an error. This section may be updated as our investigation continues.<\/p>\n

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

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

Next update by: Monday, November 24, 2025, at 9:00 PM UTC<\/td>\n<\/tr>\n
