Cloud fundamentals/Supporting cloud users/Configuring Lync online

The magazine PC Pro have an article on configuring Lync Online which gives a good outline of the process with screenshots, covering all four of the objectives below.

Managing Lync user options
There are two options you can configure for Lync users, they are to enable/disable file transfer and enable/disable audio and video. The audio and video option will need to be checked if the client is to be able to use Lync video conferencing.

Managing external communication settings
There are two options that can be configured relating to External access. The first is to enable domain federation.

The second option enables/disables public Instant Messaging connectivity. This option would be disabled in a business situation if you did not want employees to be able to message people outside of your organisation while at work.

In addition some firewall configuration will also be required as per the table below.

Configuring dial-in settings
In order to allow conference users to dial-in to get the audio content of a conference, there are a number of things that have to be configured. The first consideration is that you (as the conference provider organisation) will need a subscription for a dial-in facility with your telecom provider, and this subscription will need to be added to you 365 account. Clients do not need a dial-in subscription, but you will need to provide them with the following credentials in order to join a conference: The dial-in number is only required if they intend to use the phone network to receive order in preference to the Lync built-in audio.
 * Conference ID
 * PIN (effectively a password)
 * Dial in phone number
