Similar to the invite you received, a student's invite to VAVoyager will expire after 24 hours. If a students invite expires, navigate to the students record by clicking the “Students” tab in the top left corner of your VAVoyager screen.
Then type in your students name, select your desired student, and on the left side menu of the students record select “Student Portal Activity”.
If the student has never logged in, click the “Send Student Portal Invitation”.
Here is a quick demo of how to complete this process.
