Powershell and IBM/Lotus Domino - windows

Question

I have written 9 routines in the last few weeks in Powershell for Domino, they all appear to do what I need except 1!
This is the RegisterNewUser method, which does everything except the Email address. If I setup a user via Domino Administrator, I get everything including the email address ie internal address that is 'bob patz/smallhome'.
If I use my code this uses the registration process but all I end up with is the domain part of the internal email address '#smallhome'.
Does anyone know how to correct this? I don't think powershell uses the #formula language in any form, so I assume i somehow need to find the right column in a document or database and append the fullname in there somehow.
Is there anyone out there who can help in anyway?
regards
Mark
<#TOP TIP: THIS MUST RUN UNDER POWERSHELL (X86), ELSE IT WILL NOT WORK!!
This Powershell Function was created in March 2020 by (myself) Mark Baker as 'a' just to see if I can de-mystify
some of the Domino Database stucture, after running short bits of code and using Get-Member on some parts
of it and looking at online code snippets and reading some of the online info from IBM I have come up with
the function below to Create a New Lotus Notes User.
#
Original Code: 31/03/2020 by MBaker
A lot of work testing and diagnosing the different settings and values EVENTUALLY lead me to getting this working,
as at 08/04/2020 I just need to work out the settings for setting the correct email address per person.
#
This is how to use this function:
New-DominoUserRegistration "hazell" "C:\Program Files\IBM\Lotus\Notes\Data\ids\people\dhazell.id" "CN=Dom-01/O=Smallhome"
"Daniel" "" "swindon" "Work" "comment" "mail\dhazell" " " "password" 176
"dhazell"
Main use of this function is to connect to an IBM Domino Server and Create a New lotus notes user.

Answer 1

I now have an answer for this, this came from someone else on another board: the line [parameter(Position=9,Mandatory=$true,ValueFromPipeline=$True)][string]$fwddomain,
Needed to have [AllowEmptyString()] inserted before [string]$fwddomain, and the input field was " " and needed to be "". It appears the $fwddomain has an impact on the internal email address name ie: 'bob patz/smallhome'.
I have tested this and it shows up in the people view and also I can now send emails to other users and ones self!
Problem solved.
