If an error message appears when updating a team or deleting users via CSV batch registration, please check the following.
Error Message
"Cannot find user. Please use a format downloaded from Teachme Biz."
When It Appears
① When clicking "Confirm" under Update team in CSV batch registration

② When clicking "Confirm" under user deletion in CSV batch registration

Cause
One of the account details — "Account name," "E-Mail Address," or "Display Name" — may not match between the exported CSV and the information in Teachme Biz.
Common Patterns
- The account information in Teachme Biz was changed after the CSV file was exported.
- When the "Account name," "E-Mail Address," or "Display Name" begins with "0," saving the CSV file in Excel format caused the leading "0" to be removed.
Resolution Steps
