Try this:<br />
set-aduser -identity &quot;12345&quot; -add @{extensionAttribute12='12<wbr />35' }

Try this:
set-aduser -identity "12345" -add @{extensionAttribute12='1235' }

<div>
Set-Mailbox -Identity &quot;12345&quot; -ExtensionCustomAttribute1<wbr />2 @{Add=&quot;12345&quot;} <br />

the Identity in the command line is username not employeeID as I want to use that as the lookup for the user.

Set-Mailbox -Identity "12345" -ExtensionCustomAttribute12 @{Add="12345"}

First try the Get-ADUser with filter, without the pipeline. That shows whether there is an object found:<br />

<pre><code id="code-20-40034777-1">Get-ADUser -Filter {EmployeeID -eq '12345'}</code></pre>
Does that return an user?
