Powershell issue extracting primary SMTP while having multiple smtps - powershell

Question

Was looking around and found this little powershell script. BAsically want to be able to export all my primary SMTP and username from AD.
Get-ADUser -Filter * -Properties proxyaddresses | Select-Object Name, #{L = "ProxyAddresses"; E = {($_.ProxyAddresses | Where-Object {$_ -like "*SMTP:*" }) -join ';'} | Export-Csv -Path C:\Users\mohammad.anwar\Documents\proxyaddresses.csv -NoTypeInformation
The output would give me multiple smtp. Im looking for the Primary SMTP.

Answer 1

The logic of your query is fairly sound. There are just some syntax and operator issues with producing the result you want.
Get-ADUser -Filter * -Properties ProxyAddresses |
Select-Object Name, #{L = "ProxyAddresses"; E = {($_.ProxyAddresses -clike "SMTP:*") -join ';'}} |
Export-Csv -Path C:\proxyaddresses.csv -NoTypeInformation
Most PowerShell Comparison Operators are case-insensitive. The case-sensitive operators begin with -c. -clike should be used instead of -like when case matters.
Since ProxyAddresses will be a collection, you don't need Where-Object (if running PowerShell 3+). You can just compare the ProxyAddresses values directly. PowerShell will enumerate the collection.
I honestly can't think of a case where an account would have multiple primary SMTP addresses (the SMTP: address). So having a -join doesn't make much sense since -join attempts to join items of a resulting collection. If you want to query all SMTP addresses (including lowercase smtp:) for an account, then -join would make sense here.
In your attempt, you will see >> when the code is run at the console. The reason is because you did not close all of your open {. The hash table for the Select-Object calculated property (begins with #{) was never closed. The PowerShell console has this behavior when an opening (, {, or quote is not closed properly.

Answer 2

Try the below.
This is a very common thing with plenty of examples all over the web showing how to do this. Why do this from ADDS vs native Exchange cmdlets to get this info by default.
You can use remoting to get the Exchange cmdlets for use via your
workstation.
Of course, searching for 'PowerShell get primary SMTP address' delivers examples for Exchange native and ADDS options.
Examples:
Get-Mailbox -ResultSize Unlimited |
Select-Object SamAccoutnName, DisplayName, PrimarySmtpAddress
# Or this...
Get-Mailbox -Identity $UID |
Select -ExpandProperty PrimarySmtpAddress
# Or via ADDS cmdlets or other
Get-ADUser -LDAPFilter "(proxyAddresses=*)" -Properties sAMAccountName, proxyAddresses |
Select sAMAccountName, proxyAddresses |
ForEach {
$Name = $User.sAMAccountname
$Addresses = $User.proxyAddresses
ForEach ($Address In $Addresses)
{
If ($Address -cmatch "SMTP:")
{"User $Name has primary address $Address" }
}
}
Identify primary SMTP Address from Active Directory with PowerShell
# First, we need to get the ProxyAddresses attribute from AD :
Get-ADUser -Identity SomeUserName -Properties ProxyAddresses |
select -ExpandProperty ProxyAddresses
# Then, we need to identify the one that starts with “SMTP:” :
# We used the “clike” operators, which is case sensitive :
Get-ADUser -Identity SomeUserName -Properties ProxyAddresses |
select -ExpandProperty ProxyAddresses |
? {$_ -clike "SMTP:*"}
