Hi, After reading the thread by Alexander Ebner, I also found that dropping EAS support is a bad idea for mobile devices.
EAS caused so many problems in the past, especially with Outlook that I really appreciate the announced MAPI over HTTP support. But this can't replace the mobile support, as EAS also has functions like accepting meeting invitations etc., which may not be possible with CalDav/CardDav and IMAP separate integration, for instance. In fact I tried to avoid EAS in Outlook and resort to IMAP whenever possible, but many features i.e. around appointments won't work with that way, CalDav Synchronizer is even worse than EAS, so I had to stick with it, having weekly complaints by users about synchronization issues etc. approx. on a weekly basis. But for mobile devices, I don't see any alternative. Since recent iOS versions on iPhone, IMAP support is completely broken on iPhones too, so I had to migrate von IMAP to EAS, even though I didn't want that at all. https://discussions.apple.com/thread/255760038?page=2&sortBy=rank https://discussions.apple.com/thread/255915358?sortBy=rank So I also definitely want to see EAS support in SOGo 6, even though I hate that protocol a lot. One way I may be able to at least get a somewhat working implementation would be to use Z-Push with CalDAV and CardDAV backend, which proved to be quite OK (at least with Zarafa server), it's also extensible with its backends to integrate it tightly with SOGo, if needed. That would be my emergency-strategy for mobile device support with SOGo 6 and maybe a working code base for an EAS integration with SOGo 6.
