Error Message

Possible Error Reason(s)

Solution(s)

This email address is already in use with this SSO Provider. Use a different email address or disable SSO from your other account.

The email assigned to this sub-user is already linked to the IdP on a different 101domain account.

This email is already associated with an SSO account on our system. The user must be removed from the other account first.

The primary account is already using this email address with the selected SSO Provider. Use a different email address.

The sub-user email is the same as the Primary Account Owner's SSO email.

You cannot assign the Primary Account's email to a sub-user for SSO. They must have unique emails.
