As I promised, I bring to you how to connect a Linux Client to a O365 SfB Account.

The client name is Pidgin.

To install we need to open a shell and run the follow.

sudo apt-get install pidgin-sipe

Wait until installation finish.

Open Pidgin client, and click Add.

On Advanced Tab, add the information as follow.

NOTE: User Agent  UCCAPI/15.0.4420.1017 OC/15.0.4420.1017

On Basic Tab, fill the fields with your account information and select Office Communicator as Protocol.

If you can’t login yet. Run the following commands

 

sudo apt-get install build-essential

sudo apt-get install checkinstall

Restart Pidgin and you must login without any problem.

Unfortunately we just have IM with Pidgin client.

We have the basic Presence and IM features.

• Change Presence states
• Change Personal Message 
• IM Chat
• See Contact List.

So, if you like or need to work with Linux OS and only need SfB to Chat, Pidgin could be a option. But if you need more features like Audio/Video o PSTN you must try with other client. Sky could be the best option, I will post about Sky later.

Hope this helps you.
