Updated June 13, 2024: We have updated the additional resources below to provide additional information. Thank you for your patience.
We will be retiring the Identity Client Runtime Library (IDCRL) feature from SharePoint Online.
Office Client applications, since 2013, default to modern authentication and have a seamless experience for the end user. SharePoint Designer however requires some additional steps to support modern authentication. We recommend that all users of SharePoint Designer follow the steps in the Microsoft Community Support Article to ensure SharePoint Designer will continue to work after the final cutoff date.

What you need to do to prepare:
