If a student has created a Handshake account, but they are not in your user requests, and not connected to a different institution, or if you accidentally rejected the original request, you can still add them by following these steps:
1. Click Manage on the left navigation bar to access the Manage Students overview page.
2. Select the three dots in the top right of the page and choose Add existing user by email.
3. This will bring up the Add existing pop up message. You can enter a student's email address and select Add student to add them to your institution's instance in Handshake. A message will appear confirming the success of adding the student.
