No email addresses in outlook ContactItem via powershell - powershell

Question

When I examine a ContactItem, all of the Email#Address values are null. I have tried settings the value then printing the value. The change is reflected in Outlook, however, no value can be retrieved via PowerShell.
Below are some snippets:
$Outlook=NEW-OBJECT –comobject Outlook.Application
$Contacts=$Outlook.session.GetDefaultFolder(10).items
$Contactsfolders = $Outlook.session.GetDefaultFolder(10).Folders
$testFolder = $Contactsfolders | Where-Object {$_.Name -eq 'Test Folder'}
$testContact = $testFolder.Items(1)
echo $testContact
$testContact.Email1Address = "BobDoe3#doe.com"
echo $testContact
Here is the output of the above execution. Note I've removed some of the uninteresting information to shorten.

Something interesting that I've found while playing with different results and solutions.
I've found that both of the below queries results in the same matches which confuses me as I would have thought myString -ne '' is checking if the string is not empty. It appears that myString -ne '' and [String]::IsNullOrEmpty($myString) can both return true which seems impossible, but I think there are some cases where this could happen. Also note that IsNullOrEmpty function is extraordinarily faster.
$Listconstact=$session.GetDefaultFolder(10).Folders | %{$session.GetFolderFromID($_.EntryID).Items | where Email1Address -NE ''}
and
$Listconstact=$session.GetDefaultFolder(10).Folders | %{$session.GetFolderFromID($_.EntryID).Items | where {[String]::IsNullOrEmpty($_.Email1Address)}}
Results from tukan's answer:

Answer 1

Try Something like this:
$Outlook=NEW-OBJECT –comobject Outlook.Application
$session=$Outlook.session
$Listconstact=$session.GetDefaultFolder(10).Folders | %{$session.GetFolderFromID($_.EntryID).Items | where Email1Address -ne ''}
#only one item
Write-Host "First element mail : $($Listconstact[0].Email1Address)`n`n"
#All mails
Write-Host "All element mail :"
$Listconstact.Email1Address

Answer 2

I'm kind of fuzzy on what you are tying to achieve. To me it seems you are mixing two things together - contacts & folders.
I'm not sure if you are trying to get information from Outlook emails or Address book (since you are using folder I guess it is the first). I'll gladly rectify the solution if it is not solving your issue.
Note: I don't have identical configuration but close enough: Outlook version: 15.0.0.4420 and PowerShell version: 4.0.30319.
I'll try my best to cover what I think you are trying to solve in my eyes - Getting all contacts' email addresses (adding also subject) from received emails in "Test Folder" #Outlook.
# Making sure we have the assembly loaded
Add-Type -assembly "Microsoft.Office.Interop.Outlook"
# saving the mapping
$olFolders = "Microsoft.Office.Interop.Outlook.OlDefaultFolders" -as [type]
# new object
$Outlook=NEW-OBJECT –comobject Outlook.Application
# setting the correct namespace
$namespace = $Outlook.GetNameSpace("MAPI")
# getting all folders in Outlook inbox
$inbox = $namespace.GetDefaultFolder($olFolders::olFolderInbox)
# filtering out all but the "Test Folder"
$targetFolder = $inbox.Folders.Item("Test Folder")
# iteration on email message
ForEach($emailMessage in $targetFolder.items) {
# getting all the information from the message
Write-Verbose -message "From: $($emailMessage.GetProperty) $($emailMessage.SenderEmailAddress)" -Verbose
Write-Verbose -message "Subject: $($emailMessage.Subject)" -Verbose
}
Why MAPI namespace? Well because the MSDN says so.
I would have thought myString -ne '' is checking if the string is not
empty.
Yes it does do that. The difference is that the method [String]::IsNullOrEmpty($myString) is checking for Null OR Empty in a string. In case, when you have a $null value then you can have both true. It is not empty and is $null. (for more see what does it mean to have a $null value)
