To begin, click People then Users. From there, click Bulk User Management.
Click on the Delete tab, then click on CSV Bulk Delete Template.
Open the file that you just downloaded with Excel or another similar program. Enter the emails of the users that you wish to delete in the first column.
Save the file, then go back to your platform and click Choose File and select the template. Click Delete Users.
Alternatively, you can use the field right above the Delete Users button. Enter the emails of the users that you wish to delete and separate them with either commas (,), spaces, or enter them on individual lines.
Once that's finished, click Delete Users.
NOTE: IF YOU DELETE A USER, THERE IS NO WAY TO RECOVER THEIR INFORMATION. ALL COURSE PROGRESS, HISTORY, AND USER INFORMATION WILL BE LOST.
