Today I had an issue, where a customer told me the following problem:

User A has his employee ID P146 in the Short Name of the person document in the Domino NAB. But if a user users this ID in the “To” field of a new mail, he receives the error, that the user is not unique, when he presses F9 for name resolution.

A look in the “($Users)” view showed, that there are 2 entries with this employee ID. In the first person document this looked fine, but in the second person document you can´t find this ID ( P146 ) anywhere. Also took a look with scanEZ, but this did not solve anything.

Some investigations later I found the “trouble” >> ever heard from “Soundex” ???

Try the following: enter @soundex(“Lastname, Firstname”) in the subject line of a new mail:

And now after pressing SHIFT-F9:

This is the so called “Soundex”, which also is listed in the “($Users)” view in the Domino NAB. But if you have another employee with the ID “B653” you would receive the error, that the user is not unique when pressing F9.

So it´s working as designed…
