How to Share/Unshare on OneDrive
Sharing A File Or Folder On OneDrive
To share a file or folder on OneDrive, go to Home - OneDrive (sharepoint.com) and find what you wish to share in 'My Files'. Click the three dots next to it and click 'Share' from the drop-down menu.

On the pop-up, enter the name of who you wish to share it with and set their access rights ('Can Edit', 'Can View', 'Can't Download'). You can add a message if you wish and then click 'Send'.

The people you shared the file with will no receive an email with a link to it and it will also show up in their 'Shared' folder on OneDrive.
You will be able to see who you've shared a document with by looking at the details next to the file.

Removing Access From A Shared File Or Folder On OneDrive
To remove someone's access to a file or folder on OneDrive, return to the share pop-up by clicking the three dots and clicking 'Share' like you did when initially sharing it. At the bottom of the pop-up you will now see the icons of the people you've shared it with in the bottom left - click this.

You'll now see a list of everyone you've shared it with - click on the person(s) who you would like to no longer share with.

Click the 'Direct Access' drop-down and then select the drop-down that shows their permission level. You can now change the access level or completely remove their access.

You can return to this menu to check on various people's different access levels to a file or folder. If you have removed all sharing access, you can see this quickly in the details next to the document as it will now say 'Private'.
