Question

Email

There is a corporate mail, about 150 employees. Everyone has their own e-mail address in the form of [email protected] , we ran into a problem after the new Ivan Ivanov arrived, we don’t know how to correctly form the mailbox name for employees with the same first and last name.
Suggest solutions for this situation

Answer 1

You put yourself in a box that led to the fact that there is no solution.
One thing is clear, in order to get out of this situation, you will have to violate the scheme for generating employee mail.
Numbers, any, I would not recommend. They repel.
Use letters, and the first thing that comes to mind is the patronymic.
