If you need to edit a SharePoint file that is Read-only, try the following:
- Right-click the 3 dots to the side of the file name in SharePoint and see if it’s checked out by you or someone else. Have the person check the document back in.
- If step #1 does not resolve the issue: Open up the application (IE. Microsoft Word or Excel), go to Account settings and log out.
- Restart your computer, open up the application and go back to the Account settings and do a connection back to OneDrive or a SharePoint site.
Sometimes opening a document from the SharePoint site and choosing to Edit in the Desktop will automatically re-link the account without going through the Account settings from the application.
