In Microsoft Edge version 152.0.4191.53, Drop is retired. That is why the feature is missing.
Relevant details:
- Edge Stable 152.0.4191.53 lists “Drop is retired in Microsoft Edge version 152.”
- Earlier release notes for version 151 said Drop was being retired and noted that files shared are saved in OneDrive and text notes need to be downloaded separately.
- The EdgeEDropEnabled policy exists to configure Drop, but with Drop retired in version 152, the missing feature is expected on that version.
If access to Drop is required, check whether any needed files were previously saved in OneDrive. For older text notes, they needed to be downloaded separately before retirement.
