Updating the expiration time and role for sharing links is still limited. Although it seems possible through the Graph API Update permission, I have been unable to pass the roles as body parameters. Graph Explorer Attempts Using the following script: Invoke-PnPGraphMethod -Url "v1.0/drives/$driveId/items/$driveItemId/permissions/$($ShareLink.Id)" -Method Patch -Content @{ roles = @("read") } threw the error message “Invalid input: No Information provided to update the specifed permission” From the UI Anyone link can’t be edited Organisation link can’t be edited Specific people links can be edited Using the network tab from the browser developer tools enables identifying the endpoint to update specific people links only.
