PowerShell - Using Variables to Delete SMTP Proxy Addresses in AD

wrx7m

I am trying to create a script that will allow me to delete an SMTP proxy address on an AD user object, after prompting for some info. I have this, but it doesn't want to create the smtp address using the variables-

Import-Module ActiveDirectory
$SamAccountName = Read-Host -Prompt "SamAccountName"
$Domain = Read-Host -Prompt "Type the domain of the address you wish to DELETE"
$GivenName = Get-ADUser -Identity "$SamAccountName" -Properties GivenName | Select-Object GivenName
$Surname = Get-ADUser -Identity "$SamAccountName" -Properties Surname | Select-Object Surname

Set-ADUser -Identity $SamAccountName `
           -Remove @{proxyAddresses="smtp:$GivenName.$Surname@$Domain"} `
           -Replace @{telephonenumber="8"}

If I Write-Host on Set-ADUser, I get -

Set-ADUser -Identity jacks -Remove System.Collections.DictionaryEntry -Replace System.Collections.DictionaryEntry

Obviously, it isn't getting the correct attributes to build out the address.

If I run the Get-ADUser commands by themselves, it outputs the correct info.

Get-ADUser -Identity "$SamAccountName" -Properties GivenName | Select-Object GivenName

GivenName
---------
Jack

Where am I screwing up?

Probably either

"smtp:$($GivenName).$($Surname)@$($Domain)"

Or

('smtp:' + $GivenName + '.' + $Surname + '@' + $Domain)

Did you test your string creation on its own?

Probably either

"smtp:$($GivenName).$($Surname)@$($Domain)"

Or

('smtp:' + $GivenName + '.' + $Surname '@' + $Domain)

The first option yields the same results. The second, errors out.

I have not and am not exactly sure how to.

Yeah, the second one was missing a +

You're also trying to put an object into a string, which will only work if that object it set to print out the value you're looking for by default

So in order to access the GivenName property on the object you have you would do $GivenName.GivenName

you could just do:

$User = Get-ADUser -Identity $SamAccountName
$User.GivenName
$User.Surname

in which case your smtp string would be "smtp:$($User.GivenName).$($User.Surname)@$Domain"

Powershell is object oriented, which is super important to realize when working with it, and that is what usually gives people the problem with it, if they do not have previous experience with objects. It makes a big learning curve increase.

On you 'Write-Host' test on your Set-ADUser command, you see "System.Collections.DictionaryEntry" because that is telling you what object is there. You're creating dictionary objects, so it's not going to automatically write out the contents of the dictionary.

Obsolesce

So what you're looking at now is something like this:

Import-Module ActiveDirectory
$SamAccountName = Read-Host -Prompt "SamAccountName"
$Domain = Read-Host -Prompt "Type the domain of the address you wish to DELETE"
$user = Get-ADUser -Identity $SamAccountName
Set-ADUser $user -Remove @{proxyAddresses="smtp:$($user.GivenName).$($user.Surname)@$Domain"}
