PowerShell match names with user email addresses and format as mailto - html

Question

So i have the below script which scans a drive for folders, it then pulls in a csv with folder names and folder owners and then matches them and outputs to HTML.
I am looking for a way to within this use PS to look up the users names in the csv grab their email address from AD and then in the output of the HTML put them as mailto code.
function name($filename, $folderowners, $directory, $output){
$server = hostname
$date = Get-Date -format "dd-MMM-yyyy HH:mm"
$a = "<style>"
$a = $a + "TABLE{border-width: 1px;border-style: solid;border-color:black;}"
$a = $a + "Table{background-color:#ffffff;border-collapse: collapse;}"
$a = $a + "TH{border-width:1px;padding:0px;border-style:solid;border-color:black;}"
$a = $a + "TR{border-width:1px;padding-left:5px;border-style:solid;border-
color:black;}"
$a = $a + "TD{border-width:1px;padding-left:5px;border-style:solid;border-color:black;}"
$a = $a + "body{ font-family:Calibri; font-size:11pt;}"
$a = $a + "</style>"
$c = " <br></br> Content"
$b = Import-Csv $folderowners
$mappings = #{}
$b | % { $mappings.Add($_.FolderName, $_.Owner) }
Get-ChildItem $directory | where {$_.PSIsContainer -eq $True} | select Name,
#{n="Owner";e={$mappings[$_.Name]}} | sort -property Name |
ConvertTo-Html -head $a -PostContent $c |
Out-File $output
}
name "gdrive" "\\server\location\gdrive.csv" "\\server\location$"
"\\server\location\gdrive.html"

Answer 1

Try adding something like this to the select:
#{n="email";e={"mailto:"+((Get-ADUser $mappings[$_.Name] -Properties mail).mail)}
You need to load the ActiveDirectory module before you can use the Get-ADUser cmdlet:
Import-Module ActiveDirectory
On server versions this module can be installed via Server Manager or dism. On client versions you have to install the Remote Server Administration Tools before you can add the module under "Programs and Features".
Edit: I would have expected ConvertTo-Html to automatically create clickable links from mailto:user#example.com URIs, but apparently it doesn't. Since ConvertTo-Html automatically encodes angular brackets as HTML entities and I haven't found a way to prevent that, you also can't just pre-create the property as an HTML snippet. Something like this should work, though:
ConvertTo-Html -head $a -PostContent $c | % {
$_ -replace '(mailto:)([^<]*)', '$2'
} | Out-File $output

Here's how I would do it (avoiding the use of the AD Module, only because it's not on all of my workstations and this works just the same), and assuming you know the user name already:
#Setup Connection to Active Directory
$de = [ADSI]"LDAP://example.org:389/OU=Users,dc=example,dc=org"
$sr = New-Object System.DirectoryServices.DirectorySearcher($de)
After I setup a connection to AD, I set my LDAP search filter. This takes standard ldap query syntax.
#Set Properties of Search
$sr.SearchScope = [System.DirectoryServices.SearchScope]"Subtree"
$sr.Filter = "(&(ObjectClass=user)(samaccountname=$Username))"
I then execute the search.
#Grab user's information from OU. If search returns nothing, they are not a user and the script exits.
$SearchResults = $sr.FindAll()
if($SearchResults.Count -gt 0){
$emailAddr = $SearchResults[0].Properties["mail"]
$mailto = "Contact User"
}
You can of course send the $mailto variable anywhere you want, and change it's html, but hopefully this gets you started.
