No email addresses in outlook ContactItem via 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 = "[email protected]"
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)}}

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
