Matching ProxyAddresses to Surname and Firstname

Question

I'm trying to pull some information from AD but having difficulty. I'm trying to get a list of users that have the PRIMARY smtp address from the ProxyAddresses attribute (an array) in a specific format (SMTP:firstname.lastname*) only. I only want the ones that match "SMTP" (case sensitive) and of those only those that have the email address in the format of firstname.lastname.

Get-ADUser -SearchBase "DC=corp,DC=companyx,DC=com" -Filter * -Properties ProxyAddresses,sn,givenname,displayname,mail |
    Where-Object {$_.ProxyAddresses -clike "SMTP:{$_.givenname+$_.sn}*"} # | Select-Object proxyaddresses,displayName,givenName,sn

Answer 1

Try this:

Get-ADUser -SearchBase "DC=corp,DC=companyx,DC=com" -Filter * -Properties ProxyAddresses,sn,givenname,displayname,mail | 
Where-object {($_.ProxyAddresses -cmatch "SMTP:") -and ($_.ProxyAddresses -match "$($_.givenname).$($_.sn)*")}
