Prevent users from deleting files when accessed from a link

Hi tomaseketorp,

This behaviour is 'by design' for the Edit sharing option.

• When you share items with this type of link, people can edit files, and can add files in a shared folder
  
• Recipients can forward the link, change the list of people sharing the files or folder, and change permissions for recipients.
• If you're sharing a folder, people with Edit permissions can copy, move, edit, rename, share, and delete anything in the folder.
  

Unchecking this box means that people can view, copy or download your items without signing in.

Based on the problem you are experiencing, you may need to change the process for editing the document, such as downloading the file to complete changes for example and uploading the edited version to a different location for example.

The following article for OneDrive explains this in more detail: https://support.microsoft.com/en-gb/office/share-onedrive-files-and-folders-9fcc2f7d-de0c-4cec-93b0-a82024800c07#:~:text=Anyone%20who%20gets%20the%20link%20can%20view%20or,Microsoft%20account%20or%20your%20work%20or%20school%20account.

I hope that helps.

Pete
