Steps to bulk inactivate users in LMS:

• Prepare the CSV file

  Add a column named:

  suspended

  For users you want to inactivate, set the value to:

  1

  Example:

  username,suspended
  [email protected],1
  [email protected],1

  
• Log in as LMS Administrator

• Go to:

  Site administration > Users > Accounts > Upload users

• Upload the CSV file

• On the upload preview page, configure the settings as below:

  Upload type: Update existing users only
  Existing user details: No changes
  Allow suspending and activating of accounts: Yes
  Allow deletes: No

• Review the preview carefully

  Make sure the correct users are listed and the suspended value is set to 1.

• Click Upload users to proceed.
• Once completed, the selected users will be inactivated/suspended and will no longer be able to log in to the LMS.

Recommended: test with 1 or 2 users first before running the full bulk update.
