Lync On-Premises vs Lync Online


A common question about Lync Online (and the other Office 365 products too, but this post is Lync-centric) is “how is this different from the on-premises solution?” And there is a comprehensive feature comparison available at the Office 365 Community site, but usually the next question I get is “yeah yeah, but what does that really mean for me?”

So here’s a shortlist of the more pertinant features that you don’t get with Lync Online.

  • PSTN calling (incoming or outgoing)
  • PBX integration
  • Advanced call handling (hold, redirection, park)
  • IP Phone support (USB only)
  • Analog line support (eg. fax)
  • Response groups (ie. Direct inbound call to a recipient group)
  • Persistent group chat
  • Skill search from SharePoint (either on-premise or online)
  • Client-side recording
  • Dial-in conferencing
  • Interop with on-premise video conferencing systems (eg. Polycom suites)
  • QoS
  • Quality of Experience Reporting

This usually leads to a question like, “ok, so what do they have in common then?”

So for completeness, here’s some of the more popular things you can do with both versions of the product.

  • PC-to-PC audio/video
  • Address book search
  • IMPresence
  • Office application integration (click-to-chat)
  • Federation with Lync Online, Lync On-Premise, and OCS On-Premise
  • Application/Desktop/Whiteboard/Presentation sharing
  • Online Meetings
  • Guest attendees (via rich client and web client)
  • Roundtable support
  • Meeting lobby

Hope that’s helpful. ¬†Might add SharePoint Online and Exchange Online comparisons too.
