ActiveSync

[fbartels]

@andreasdueren the macOS mail app only implements ews (exchange webservices) and not eas (exchange active sync).

@andreasdueren FYI, I found this Apple reference and it seems to imply a difference between mac OSX and iOS/iPadOS support... which was more clearly summarized by @fbartels:) And this Microsoft reference on the difference between EAS and EWS.

@nebulon Many thanks for this !
It seems to work pretty well, take my subscription Cloudron !

@nebulon ActiveSync is kinda hard on resources. How can I disable it, so that my users cannot use it? I tried to edit the nginx.conf in the SOGo pack via terminal, but it's read-only, so I don't wanna mess with it.

[nebulon]

How is this showing up resources wise? I would assume this will only impact, if active sync clients are used.

[Jarod]

@nebulon I added three of my accounts on my iPhone. In roundabout 5 seconds, it produced more the 500 lines of log. And this all the time.

[nebulon]

Have you tried to use imap/smtp instead of active sync on the iphone then?

[Jarod]

@nebulon Yes. It works way better. The question still is, how I can block active sync. I have roundabout 30 user on my instance and I don't want one to accidentally ActiveSync.

[nebulon]

ActiveSync is indeed a bit hard to test from my side. Is the main reason here that the logs are flooding the system or something else? Maybe we have to reduce logging. Have you looked upstream with SOGo to get some info on active sync and resource usage?

[Jarod]

@nebulon I cannot really post a log, because most of them contains folder names but it seams, that every device goes through all of its folders very often and it gets logged. 10 seconds of log, after the initial sync with the device, contained without spaces, 49534 letters in 53 lines. Mostly LIST and stuff like that.

[nebulon]

Have you tried to reduce the debug logs by editing sogo.conf in the app? For example there is SOGoDebugRequests which may be good to have to NO and there are potentially other config variables (after editing the file you have to restart the app).

I have disabled the verbose logging now in the latest package. I will look into making ActiveSync optional next.
