Bopup Messenger is a business messenger that helps offices and organizations in any sphere to organize and improve their IM and real-time communications over LANs, WANs and large networks including connections over Internet. It requires an IM server and provides encryption of personal instant messages and group file transfers. That makes private conversations and user collaboration more safe and secure.

The messenger offers a great functionality on sending and receiving instant messages with formatting font and color, insertion of URLs, links and emotions (smileys) into the text of messages. Since the communication is organized via a central IM server an offline messaging and document exchange are provided. Bopup Messenger sends messages and files even a recipient is not available and receives stored offline data from the communications server. New versions are automatically downloaded and installed from the instant messaging server so there are no needs to handle installations and deploy updates manually on user workstations. This IM client has a built-in branding support that shows a company logo uploaded on the server in the messenger interface.
