Hi @dineshjmsbw25,

This Knowledge article might be of use:

Updated User Email Results in User with Old Email Does Not Exist in Auth0 Database

Problem statement This article addresses the situation in which an admin is not able to update specific user emails with custom DB import OFF. The update results in error: 400: User with old email does not exist in Auth0 database Solution This error appears when the user has logged into Auth0 using the given email, and then the user’s email has been changed/updated in the legacy DB (for the same user_id ). Now, since the import mode is OFF, and there is no user profile in the legacy DB agains…

YOu can try to check if the user still has the same inside of the database.

If you have any other question feel free to ask us.

Have a good one,
