I have read some reports of problems with ActiveSync e-mail on the new iOS. Reading between the lines, it seems to only affect mail server running in a Windows OS. I have kerio Connect 9.2.1 running on Linux (Debian). Will my users have problems if they upgrade the iOS? I've asked them to hold off for now.

Windows is not the problem. It can happen to all platforms if a http/2 connection is established. This can happen too if you are running a nginx proxy server with http/2 config. It es a 'feature' from Apple and everyone has to deal with it (disabling http/2 answers if you can). On Windows server 2016 it can be done with a registry change and fix this 'bug'
