Hi,

Here how to start up your installation.

My OS: CENTOS 7

Pidgin Version: Pidgin 2.10.11-5.el7 (libpurple 2.10.11)

1-Pidgin will require EPEL repository. you can skip this if u have already install Pidgin.

#yum install -y epel-release

2- install pidgin software with its plugin sipe.

#yum install -y pidgin pidgin-sipe

3- Open your newly installed pidgin. click on add account.

4- Go to basic tab. Choose protocol Office Communicator.

5- Go to Advance tab. 

Server[Port] : <your server name, please get your office communicator server address> eg: ocs.example.com

Connection Type : <depends on your server confir> eg:SSL/TSL
