In Skype For Business, when used internally on-premise, the new meetings button always shows "You don't have anything scheduled. Enjoy:)". We utilize Exchange 2010 and Outlook 2013. Externally, when accessing Skype via our Lync 2013 Edge servers, the meetings do show up, but not internally via the FE.

Hi,

S4B uses your Exchange's autodiscover url or the one configured for your EWS internal url.

If you can't access this internally I suggest confirming you can access your autodiscover.domain.com address internally this will cause your calendar integration to break.

Did you try to use Outlook's "Test E-mail AutoConfiguration" option to verify that Autodiscover.<yourdomain> is working properly, in addition to making sure that this FQDN resolves to a reachable and functional Exchange 201x CAS server?

Thanks / rgds,
