Microsoft OneDrive makes it easy to share photos, Microsoft Office documents, other files, and entire folders with people. Otherwise, the files and folders you store in OneDrive are private until you decide to share them and you can see who a OneDrive file is shared with or stop sharing at any time.
There are two ways you can share files and folders in OneDrive but beware that these options may vary slightly between OneDrive and OneDrive for Business, especially if your organisation has restricted content settings.
How To Share Files With Copy A Link To Paste In A Text Message, Email or Website
Choose this option to share items with lots of people you might not even know personally. For example, you can use these links to post to Facebook, Twitter, or LinkedIn, or share in email or IM. Anyone who gets the link can view or edit the item, depending on the permission you set. Users with the link cannot upload new items. Keep in mind that the link can also be forwarded and sign-in is not required.
How To Share Files By Sending A Link Via Email
Choose this option if you want to send an email invitation to people or groups and keep track of who you invited. This lets you also remove permission for specific individuals or groups later if you need to.
When you share folders with Edit permissions, people you share with can add the shared folders to their own OneDrive. This lets them keep the folder alongside their own folders and items, easily move items between folders, and more easily work on it offline. Any updates they make sync with the shared folder, so everyone with access to the folder is up to date.
NOTE: The recipient can add shared folders to their OneDrive, not individual files. If you want the recipient to add files to their OneDrive, put the files in a folder first, and then share the folder.
