Just wanted to pass on I use eM Client for my Exchange email. I was able to get it working but it will randomly crash. The crash issue isn't very frequent and it may be something specific to this build of Linux or something, but below are the settings and programs I used.
Host OS: Kubuntu 16.04
Bottle OS: Windows XP
Crossover Version: 15.2.0
eM Client Version: 7.0.26687.0
Programs needed:
-.Net 2.0 SP2
-GDI+
-eM Client (of course)
Make a new bottle, install .Net 2.0 SP2, perform the reboots it requests, install the GDI+ package to the same bottle, reboot as needed and then install eM Client to the same bottle.
With that said, when I initially made the bottle, I tried to install eM Client first. That's when I discovered the missing dependencies. I don't think installing eM Client is necessary at first, but if something doesn't work, start from scratch and install eM Client before and after the .Net and GDI+ stuff.
If there is an additional information needed, please let me know. Thanks!
