The telephone tab in AD Users and Computers has a Notes section. This can be manipulated in a similar manner to the street address field on the Address tab. The Notes field on the GUI stores its data in the info attribute.

$ou = "OU=BlogTests,DC=Manticore,DC=org"            
            
$note = @"
Once upon a time something happened

In a galaxy far away

Use a here-string to create the text – ensures line breaks are honoured.

Use the –Replace parameter with the Microsoft cmdlets and –ObjectAttributes with Quest cmdlets.

The provider requires Set-ItemProperty and the script is a straight setting of the info attribute.
