Lync On-Premise vs Lync Online (Office 365)

Companies are curious to know, which of the three available Lync solutions suits them.

Implement Lync Hosted or on-premise or Office 365/Lync Online: that is the question?

To start out, the most important thing is to determine the needs of the company – and based on these needs we can identify the Lync solution that fits best.

In my opinion, and because “I love to have control and access to all features”, I have to say that I prefer Lync Hosted or On-Premise.

So we can have the following implementation scenarios:

  1. Lync Hosted or on-premise
  2. Office 365
  3. Lync Online

Following are the advantages and disadvantages of all three options.

For starters, the Lync Online and Office 365 are located online on the cloud. These solutions are low-cost, but are lacking key features that are important to many organizations.

Data Security and Privacy

Hosting Lync online release the organizations of deploying more hardware, managing licenses, and it is very easy to setup. But it can seem elusive to get access to data and find where it is stored

So please before implementing Lync Online, you must read the Microsoft EULA carefully. Microsoft has rights to all analytics, inclusive data that is stored in their datacentre. This is also depending on the privacy laws in each region. But this data is not available for you, so you don’t have the possibility to use the reporting features.

So what is the best solution for you?

As mentioned above, this depends on your needs:

You can also take a look on the Client comparison tables for Lync Server 2013 (These tables indicate the features that are available to Lync users in an on-premises deployment of Lync Server 2013. The same features are also available to Lync Online and Office 365 users unless otherwise indicated).


All the Lync options are valid, so if you want to get the best option for your organization, do not hesitate to contact us, and we can design the best solution for your needs.
