Can anyone help me in fixing this issue. On Lync 2010 Std and edgeserver ,i am getting this message
Microsoft Lync 2010 cannot start. The product license may be expired because you are using a pre-release or evaluation copy of the program, or the product key information may have been modified in your Windows registry. Please uninstall and then reinstall Lync.
I Install this as evaluation and already have migrated some user's from ocs 2007 to lync 2010 ,but now they cannot even login on lync 2010 because of license ..
I have the license key but i don't know where to put and how it fix it and make it work again..
