In early 2017, Microsoft began deprecating the use and support of Exchange ActiveSync (EAS) in Outlook for Windows. However, EAS remains the industry standard for synchronizing mobile devices. Additionally, Microsoft has discontinued support for SharePoint Sync outside of Microsoft 365 (Office). As a result, users currently relying on these protocols for Outlook synchronization should transition to one of the supported alternatives listed below.

It’s important to note that some email clients may display certain features as Not Available (N/A). This is not a limitation of SmarterMail for Linux and Windows but rather a restriction of the protocol itself or the client lacking that specific functionality. Furthermore, numerous email, calendar, and contact management applications exist across all operating systems, far too many to list individually. WebDAV is included as it encompasses CalDAV for calendar sync, CardDAV for contact management, and other essential collaboration features.

For optimal email hosting, secure communication, and seamless synchronization across Windows, Linux, and mobile devices, SmarterMail supports multiple industry-standard protocols, ensuring maximum compatibility and performance.
