Outlook LAN Messenger is a robust instant messaging system designed for intranets and group communication. Reminiscent of older MSN Messenger versions, it excels in security, versatility, and simplicity. User access is tightly controlled via IP addresses, ensuring a secure internal communication channel managed by administrators. Ideal for businesses and workgroups, it allows the creation of multiple user groups and includes predefined ones for common business areas. Features include an appointment calendar, open group chat, secure file transfer, various connection states, and more. Outlook LAN Messenger offers a secure, user-friendly solution for efficient workplace communication.

The app works mostly well. I like the speed of messages and file sharing, but I find that it can crash occasionally. It’s useful, but definitely needs some fine-tuning to reach its full potential!
