Under Other settings, you can set any of the options below. Once you have set all your link settings and permissions, click Apply.

If you're sharing a folder, people with Edit permissions can copy, move, edit, rename, share, and delete anything in the folder they have access to.

However, they cannot make changes to the version on your OneDrive.
Block download prevents people from downloading the file or folders they have access to. Unchecking this box means that people can download the files onto their devices.
Set expiration date lets you set a date for the link to expire. After the date you set, the link won't work anymore and you will need to create a new link for users requiring access to your file or folder.
Set password lets you set a password to access the file. When a user clicks the link, they will be prompted to enter a password before they can access the file. You'll need to provide this password separately to anyone you want to share the file with.

Select Copy Link and then select Send. Paste the link and send the link where you want to send it, like an email, message, or post.
