Advantages and Disadvantages of Cloud Attachments 
  1. You cannot open a Cloud Attachment directly from OneNote with native software.
  2. It only provides a link to jump to the Web page. Open attachments with Web online tools for editing. If the network is impassable, it cannot be manipulated. (Especially in some countries, which cannot access, Microsoft Personal accounts cannot be opened Cloud Attachment for editing, and the preview is also not displayed).
  3. The preview diagram can only be viewed and cannot be edited.
  4. To edit a cloud attachment using local native software, use the OneDrive.exe client. Synchronize the "OneNote Uploads" folder, locate the file, and then edit it.
  5. Only Office files will have a preview. Other files do not have a preview diagram.
  1. Some files can view the preview directly (if the network allows).
  2. If the preview is too large and wide, you can scroll through the scroll bar.
  3. The preview is reloaded each time when the page is opened.
  4. With the “Gem Menu for OneNote UWP” add-in, you can edit the Cloud Attachment directly with the local software from OneNote UWP.
Good Use Cloud Attachment with Add-In 
We can directly use the “Gem Menu for OneNote UWP” add-in, after synced completely “OneNote Uploads” folder in on the OneDrive.exe client.

With the “Cloud Attachment Link” on the OneNote UWP page, use the local native software to open the corresponding files in the "OneNote Uploads" folder for editing.

This allows you to achieve the perfect degree of use of Cloud Attachments.
