Aktueller Stand
We've identified that a recent update to the Microsoft 365 Copilot app changed how it handles SharePoint and OneDrive sign-in requests and is causing the affected requests to be passed to the app in an older format, resulting in authentication failures when users open the cloud file picker to add knowledge. We're deploying a code fix that we've developed and we estimate that it'll complete deployment by our next scheduled communications update.
Mehr Informationen
Specifically, opening the SharePoint and OneDrive file picker to add knowledge fails with the following message:
"Failed to authenticate. Please try again."
To bypass impact, users may go to Knowledge, then Add knowledge, paste the SharePoint and OneDrive file or site URL into the search box instead of using the cloud picker.

Users located in Europe, United State, and Japan attempting to open the SharePoint Online and OneDrive file picker in Agent Builder within Microsoft Copilot may be impacted by this event. This section may be updated as our investigation continues.
