Hi,

We recently transitioned from shared-hosted Exchange/Lync 2010 to on-premises Exch/Lync 2013.  Both before and after the change our clients use Outlook 2010 and Lync 2013 Basic.  After the migration, clients no longer have the 'New Lync Meeting' button on the ribbon bar in Outlook.  When I go into Manage Add-ins in Outlook the 'Lync Meeting Add-in for Microsoft Office 2013' is disabled and it will not let me enable it.  We use the same email address domain for both Outlook/Exchange and Lync.  I cannot find anything that explains why this option is missing in our current setup, so any help would be appreciated.

Hi,

What does it mean by "it will not let me enable it"? Is it greyed out?

You may need to try to enable the Lync Meeting Add-in for Microsoft Office 2013 from the registry:

Important Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.

• Exit Outlook if it is running.
• Press the Windows function key, search for "regedit," and then click OK.
• In Registry Editor, locate the following subkey:
  
  HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins\UcAddin.LyncAddin.1
• In the details pane, double-click LoadBehavior. If the value in the Value data box is not 3, change it to 3 and then click OK.
• Exit Registry Editor.
• Start Outlook.

When the value of LoadBehavior is set to 3, the add-in is enabled.

I hope the information is helpful.
