ChatGPT advice on the changes is interesting; thought-provoking alternative to opening IMAP ports, configuring TLS, DAV endpoints, working out testing and implementing across multiple end device types: “reconsider the server/product mix” Activesync is simple - for back-end config, access/connectivity, and also for devices. Can the alternatives work - yes… but I'll be looking for alternatives :( Simon What SOGo v6 is changing * The SOGo team says v6 will drop ActiveSync and “replace [it] by … MAPI over HTTP,” while SOGo remains a CalDAV/CardDAV server. That’s great for Outlook-desktop interoperability, but it removes the only protocol most phones use for combined mail+calendar+contacts. sogo.nuSo how do phones connect in a post-EAS SOGo world? Use the open standards SOGo has always been strong at: iOS (built-in apps) * Mail via IMAP/SMTP (SSL/TLS). * Contacts via CardDAV; Calendar via CalDAV (both are natively supported profiles on iOS and can be pushed by MDM if you use one). Apple Support+1 Android * Mail via your preferred IMAP client (e.g., Gmail app configured for IMAP, or another IMAP client). * Contacts & Calendar via DAVx⁵ (adds CalDAV/CardDAV sync into Android’s native Contacts/Calendar). davx5.com+1What about Outlook mobile? * Outlook mobile doesn’t speak MAPI/HTTP to on-prem servers; its supported on-prem path has been ActiveSync. Without EAS, Outlook mobile won’t give you calendar/contacts sync to SOGo. If you must use Outlook mobile, you’d be limited to IMAP-only mail (no first-party CalDAV/CardDAV in Outlook mobile). Microsoft Learn+1Practical migration plan * Audit devices & apps – list who uses iOS Mail, Samsung Mail, Nine, Outlook mobile. * Decide new client combos * iOS: Mail (IMAP) + built-in CalDAV/CardDAV accounts. * Android: IMAP mail app + DAVx⁵ for contacts/calendars. davx5.com * Publish clear settings – IMAP/SMTP hostnames, ports, TLS, auth; CalDAV/CardDAV endpoints (SOGo URLs). (SOGo v5 docs show how you expose CalDAV/CardDAV; v6 keeps this model.) sogo.nu * MDM profiles (optional but nice) – Push iOS IMAP/CalDAV/CardDAV profiles so users don’t hand-enter settings. Apple Support * Pilot with a few users, then roll out comms and cutover date aligned with your SOGo v6 upgrade.Decision points for you * If you have heavy Outlook for Windows users: MAPI/HTTP in SOGo v6 is a win for desktop experience. Microsoft Learn * If you’re committed to Outlook mobile (with full calendar/contacts on phones), MAPI/HTTP won’t help; you’ll need to standardise on IMAP + CalDAV/CardDAV, or reconsider the server/product mix.

Please list here, I’m curious to know. I did not find any viable one anymore. Both Nine and BlueMail do not count any longer as both are buggy. The standard Gmail app sort of works but cannot be used if your SOGo e-mail address happens to also be your Google account’s e-mail address. And someone mentioned the Outlook app for Android but I could not get it working and it is also said to store credentials and user data in Microsoft cloud – bad. So, any other option? Which? Kai-Uwe Rommel From:[email protected] <[email protected]> On Behalf Of Kees van Vloten Sent: Thursday, October 2, 2025 9:52 AM To: [email protected] Subject: [Marketing Mail] Re: [SOGo] SOGo 6 no Activesync Hi Quentin and team, ActiveSync is great for mobile devices: * Every mobile (mail-client) supports it * Users go through one setup for mail, calendar and addressbooks, i.e. user-friendly setup as well. * From my perspective ActiveSync also allows for pre-authentication, a poor-mans 2-factor authentication which is not possible with regular imap/smtp mail. * It is hard to replace because users have to get instructions how to change the mail on their phones. I hope you can revisit the decision to stop with ActiveSync as I find it an easy, simple and relatively secure solution for external / mobile email. - Kees Op 02-10-2025 om 07:03 schreef Kai-Uwe Rommel - ARS ([email protected]): See my message to this list a couple of days ago about ActiveSync apps for Android. I really also like how ActiveSync works (e.g. only one account/connection to configure in one single app for mail, calendar and contacts). However, during the search for a suitable app I could only learn that almost anyone is abandoning it, even Microsoft. We recently got the problem that BlueMail on Android which had supported ActiveSync for a long time did suddenly not work properly any longer due to its latest update. That was the trigger why I searched for an alternative. We had used Nine before BlueMail and when I now checked Nine again I learned that the vendor does no longer maintain it in favor of a new solution which is a cloud based solution and stores user data there. So I could only decide to drop both of these and switch to Thunderbird and DAVx5 on Android. (We do not use iOS here. And we use Thunderbird on the Desktop, anyway.)

I have seen that the activesync server will be replaced with MAPI over HTTP. This is a big feature drop for all our customers. How ist the plan from SOGo to connect mobile phones without the need of additional apps or configuration in the future? MAPI over HTTP is a feature that only is used from outlook. What is with all other clients that preferred using Activesync ?
