  • & (Ampersand)

Resolution

In case it is required to use unsupported special characters in usernames, perform the update via Employee Import instead of through Manage Users

  1. Go to Admin CenterEmployee Export, and download the User Directory File.

  2. Update the username field in the CSV file with the required values.

  3. Import the file through:

    • Employee Import (for non-EC instances), or

    • Import Employee Data (for EC instances).
