Making script read a CSV and output answer - csv

Question

I am looking to add a line(s) into a PowerShell script. I want to get my script to check if something exists in a CSV it will give a true/false response.
Basically I have a script to remove user access from O365 and AD including and mailbox changes.
My company also uses a lot of external portals which need removing manually.
I would like it to check the $EmailAddress input against CSV's (i.e DomainHostAccess.CSV, WebsiteHostAccess.CSV, SupplierAccess.Csv) then if there name is in the list it will output something similar to;
DomainHostAccess | True
WebsiteHostAccess | False
SupplierAccess | True
that way we know that we need to manually log into these services and remove accounts.
I have looked on the posts on here already and couldn't find anything suitable, I am fairly new to PS and this is a little advance for me so I would appreciate any help that can be given.

Answer 1

You could try something like this
$UserList = Import-Csv -Path C:\EmailAddress.CSV
$UserData = Import-Csv -Path C:\DomainHostAccess.CSV
ForEach ($Email in $UserList)
{
$userMatch = $UserData | where {$_.Name -like $Email.Name}
If($userMatch)
{
Write-host $Email.Name "Domain Access True"
}
Else
{
Write-host $Email.Name "Domain Access False"
}
}
You would need to have headers on your CSVs for this check to work.
