I much prefer the old OCS way of enabling users for OCS / Lync, I believe it was much easier, but it looks like we are going to have to get used to using Powershell to do this. An example I have put together to enabling all users in an Organisational Unit for Lync 2010 is:

get-csADuser -OU "OU=Users,OU=Head Office,dc=danovich,dc=com,dc=au" | Enable-CsUser -RegistrarPool pool01.danovich.com.au -SipAddressType emailaddress
