ProxyAddresses Script

[Andy2789]

Hopefully someone with far better script writing skills than me, can help me!

 

We are using Office 365 and have been for a number of years, but over the summer we are changing our username layout for students and staff over the summer as part of a complete overhaul. We need to add their existing username plus @ domain.com to the ProxyAddresses attribute. So when Azure resyncs after the changes their old email alias will still work for each user. I have searched Edugeek, the internet over and over and all other scripts either want to add a second domain, or replace everything that is there.

 

If anyone can point me in the direction of a script that on bulk will go to each user, take the username add the @ domain.com and add it to ProxyAddresses Attribute I will be a very happy man!

$Users = Get-ADUser -filter * -properties proxyaddresses
$Users | Foreach {
    get-aduser -identity $_.Name | set-aduser -add @{ProxyAddresses="smtp:"+$_.name+"@domain.tld"}

 

That ought to do it.

Wow! Wasn't expecting such a quick response!

 

Thank you, will give it a whirl now.

Don't forget you will need to update 365 logon credentials if you want users to login with their new username format
