True Microsoft Outlook
Integration and Compatibility

Don't be fooled by imitators claiming Exchange + Outlook functionality on the one hand, while requiring Outlook plug-ins or proprietary email clients on the other. With SmarterMail, users can connect Microsoft Outlook natively, just as they would with Microsoft Exchange, thanks to SmarterMail’s built-in MAPI support. SmarterMail delivers enterprise-grade email without the need for additional software, Outlook plug-ins, or per-user fees.

SmarterMail and Exchange

SmarterMail stands out as the only email server that offers native MAPI support on both Linux and Windows platforms! While most other mail servers depend on unreliable third-party plug-ins for Exchange-like functionality, SmarterMail provides a seamless experience with full Outlook integration. Say goodbye to buggy Outlook plug-ins and complex management. SmarterMail is a stable and complete email solution on both operating systems.

All Outlook Versions Supported

With a native implementation of MAPI over HTTP and Exchange Web Services (EWS), SmarterMail delivers seamless Microsoft Outlook compatibility on Windows servers. Users can experience full Exchange-level features including email, calendaring, contacts, and tasks on macOS, or Window environments. By offering a true alternative to Microsoft Exchange, SmarterMail ensures businesses can deploy their email and collaboration solution on their preferred operating system, maximizing flexibility and performance.

The Power of Exchange

Experience the versatility of SmarterMail on both Linux and Windows! Enjoy all the capabilities of Microsoft Outlook as if you were using on-prem Exchange or Microsoft 365, including:

  • Public Folders
  • Contact Groups
  • Delegation
  • Create and manage client Rules
  • Categorize / tag calendar appointments, contacts, notes, and tasks
  • Add attachments to calendar appointments, contacts, notes, and tasks
  • Follow ups / To Dos
  • And much more!

Outlook Compatibility

SmarterMail is compatible with current versions of Microsoft Outlook for macOS and Windows. Older versions of Outlook, unfortunately, offer very limited Exchange functionality for Outlook.

Supported versions include:

  • Outlook 2021
  • Outlook 2019
  • Outlook 2016
  • Outlook for Microsoft 365 (Office)
  • Outlook for Mac

NOTE: Due to changes Microsoft is making to the "New Outlook", it no longer supports adding accounts from on-premise Exchange servers. As a result, it does not work with SmarterMail.
