What does the error "This email is already taken. Try another email" mean?

Issue symptoms

When I bulk update users with a CSV file, I receive an email with the link to download an Excel file. This file includes the following error referencing one or more users:

Email: User couldn't be updated - This email is already taken. Try another email.

Resolution steps

This error means that you tried to update a user with an email that is already being used by another user.

Steps to resolve

• Search for the email address referenced in the error to confirm if this user already has an account. Merge the users together or delete the existing user.
• Check if this email address is being used as a support address, then remove it as support address.
