It might happen that you installed lync 2010 pool in enviroment that you still have the OCS 2007 server pool functioning.Suddenly you decided to decommission and totally remove the OCS pool, while you still have users that are not enabled for neither ocs 2007 nor lync 2010 pool. You open the lync 2010 control panel then you search for those users and try to enable them oooops you got the below error.
ok that’s fine, then you decide to use the enablecs user command using the lync powershell command tool, and now you get the following error “Can not Move Legacy user in enable operation”.
ok here is what you have to do open up adsiedit.msc, navigate to the user’s object, open the properties, and removing or setting the following attributes to “<not set>” and “0”:
see image below:
after doing so go and run the following command:
Enable-CsUser -Identity "Pilar Ackerman" -RegistrarPool "atl-cs-001.litwareinc.com" -SipAddress "sip:firstname.lastname@example.org"
