IceWarp
Business Email & Collaboration Suite Made in the EU
IceWarp is a business email and collaboration suite that brings email, TeamChat, video conferencing, document collaboration, calendar, file storage, and notes into one workspace. It is designed as an alternative to Microsoft Exchange and can be deployed either as a fully managed cloud service or self-hosted on an organization's own infrastructure.
The platform includes an email server with SMTP/ESMTP, IMAP, and POP3 support, Active Directory/LDAP integration, multi-tenant architecture, and anti-spam and antivirus protection. Collaboration features cover real-time document editing, WebRTC-based conferencing with webinar mode, TeamChat with XMPP bridge support, CalDAV and CardDAV, and Exchange ActiveSync for mobile synchronization. An API layer, Outlook Sync integration, and a ChatGPT integration for summarizing and generating content are also available. Desktop apps for Windows and Mac and mobile apps for iOS and Android extend access beyond the browser.
IceWarp is aimed at businesses and organizations seeking a self-managed or vendor-hosted collaboration platform, including those migrating from Microsoft environments. It is offered through cloud and self-hosted editions, with license renewal and upgrade options, migration and deployment services, and SLA plans for support coverage.
