Skype for Business Online to On-Premises Migration

Okay guys – you’ve been told “lets move everyone back from the cloud! We need Enterprise Voice for our users” This will go against most Microsoft sales materials as we should be looking towards cloud.

Hybrid Exchange 2007/2013 and Lync EWS Integration

I came across an interesting issue recently with a client currently running Exchange 2007 and looking to migrate to Exchange Online. Since Update Rollup 10 for Exchange 2007 Service Pack 3, it has become possible to coexist Exchange 2oo7 and Exchange 2013.

Office Web Apps Server used be called Web Application Companion (WAC) and that is what all of the Lync 2013 pre-release software and documentation called it. In my opinion, Office Web Apps Server is a very confusing name as Exchange Outlook Web App (or Access) has owned the OWA acronym since 1997 with Exchange 5.0… [Keep reading] “Office Web Apps Server – just say no to Windows Update Automatic Updates”
