A Microsoft file hosting and synchronization service.
Dear respected Adam Cota,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
As per your description, based on my test(I just tested from my side) and it seems that I cannot meet the same behaviour as like you described above. When I click on OneDrive icon in the notification area on the taskbar, click on 'Settings'. Notifications section, I see the option for 'Notify me when many files are deleted in the cloud'.
If the "Notify me before many files that I deleted on my PC are removed from the cloud" option is missing from the OneDrive settings for a specific user, first please check OneDrive Version, ensure the user's OneDrive is updated to the latest version (OneDrive release notes). Sometimes, features can be dependent on specific versions, and updating could restore missing options.
Also, if possible, could you please try the unlink/link again the account from OneDrive sync client app and see if there is any difference.
Also, **** verify which type of account(OneDrive for Business or personal OneDrive) problematic user using.
Please understand that our initial reply may not always immediately resolve the issue. However, with your help and more detailed information, we can work together to find a solution.
Appreciate your patience and understanding and thank you for your time and cooperation.
Sincerely,
Waqas Muhammad
