We recently migrated from shared-hosted Exchange/Lync 2010 to on premises Exchange/Lync 2013.  Since the move, some clients no longer have the 'New Lync Meeting' button on the Outlook ribbon.  We are using Outlook 2010 and Lync 2013 basic.  When I go to manage Add-ins in Outlook, the 'Lync Meeting Add-in for Outlook 2013' is disabled and it will not let me enable it.

We have the same email address domain for both Exchange and Lync, I have installed all the updates for office & Lync client and I have un-installed Lync and run Office Repair.  I am out of ideas.  

Any help would be appreciated.
