Latest Message<\/th>\nTitle: Users may be unable to save their personalization settings within Microsoft Copilot Chat and encounter an error<\/p>\n

User impact: Users may have been unable to save their personalization settings within Microsoft Copilot Chat and encountered an error.<\/p>\n

More info: Affected users may have seen a banner stating, “Something went wrong, and we couldn’t save your changes. Try refreshing the page.”<\/p>\n

Final status: Our fix completed saturating the affected environments on Friday, March 20, 2026, at 11:30 PM UTC, and after an extended period of monitoring, we can confirm the issue is resolved. <\/p>\n

Scope of impact: All users attempting to save preferences within the Microsoft Copilot Chat settings page may have been affected.<\/p>\n

Start time: Monday, March 16, 2026, at 12:00 AM UTC<\/p>\n

End time: Friday, March 20, 2026, at 11:30 PM UTC<\/p>\n

Root cause: The API that facilitates settings saving was set to a prior, deprecated version of the Copilot model.<\/p>\n

Next steps:
– To help prevent similar impacts in the future, we’re further reviewing our testing and validation processes prior to deployment.<\/p>\n

We’ll provide a preliminary Post-Incident Report within two business days and a final Post-Incident Report within five business days.<\/td>\n<\/tr>\n
