If you have a small to medium business and you require a professional collaboration server that focuses on the main services of emails and calendar scheduling, I recommend IceWarp.
IceWarp is an affordable team communication solution that combines chat rooms and file-sharing. It scales efficiently for large user bases without needing dedicated administrators. Features include smart documents, data archiving, and TeamChat for enhanced collaboration. However, limited exchange compatibility, cumbersome maintenance, lack of certain automated features, problematic email archiving, and inadequate API integration, along with insufficient technical support, present challenges for tech buyers considering implementation.
