davmail

DavMail is an open source gateway that enables users to access Microsoft Exchange and Office 365 accounts through standard mail and calendar protocols. It eliminates the need for Outlook by allowing any mail client to connect to Exchange servers, whether on the local network or remotely through Outlook Web Access.

Key Features

  • Multi-Protocol Support : POP, IMAP, SMTP, CalDAV, CardDAV, and LDAP protocol gateways in a single application
  • Exchange & Office 365 Compatibility : Seamless integration with Microsoft Exchange servers and Office 365 accounts
  • Cross-Platform : Runs on Windows, macOS, Linux, and supports Docker deployment
  • Mail Client Flexibility : Works with any standard mail client that supports the above protocols

Use Cases

  • Mail Client Freedom : Use your preferred mail client instead of being locked into Outlook
  • Remote Access : Connect to Exchange accounts from anywhere through Outlook Web Access
  • Calendar & Contact Sync : Synchronize calendars and contacts alongside email using CalDAV and CardDAV
  • Legacy System Integration : Bridge older or non-Microsoft applications with modern Exchange infrastructure

Who Is It For

DavMail is designed for users and organizations who need flexible access to Exchange and Office 365 without using Outlook, IT administrators managing heterogeneous mail client environments, and developers seeking an open source Exchange gateway solution.
