RM491023SharePoint: Optical Character Recognition (OCR) Backfill for SharePoint Sites
Summary
We are thrilled to announce a powerful new feature that allows tenant admins to select an existing SharePoint Online (SPO) site and backfill OCR for documents already present in the library. This means you no longer need to move all your documents to a new site to ensure they are OCRed and protected.
