Franc,
Do you work in an office setting, i.e., law office like me? We use Outlook for all of our calendar deadlines and appointments, as well as email of course. It is an INTEGRAL part of everything we do. I notice you didn't address the Adobe plug-in. I suggest you guys work on getting that issue fixed (if you were part of this redesign) because many people in my industry rely on this plug-in to seamlessly convert our emails into PDFs, among other things. And while I respect your opinion about the new Outlook, to me and many others, it is NOT well designed and implemented. What Microsoft does not seem to understand is those of us who use these programs daily, minute by minute, do not appreciate and do not want a complete overhaul to something that was working just fine.
I have tried every color scheme offered in the new version and NONE of them give me what I want and prefer, which is a gray color (shown in pic 1 below)....not black and not colorful. Gray is the easiest on my eyes and provides the best contrast for unopened emails and other things (in my opinion). Example below.
Also, the search function in the calendar is horrendous and practically useless. I use this feature daily to check entries on particular case files with the ability to see multiple entries plus how they are color categorized. In the new version, instead of just listing my entries in chronological order (shown in pic 2 below), it is grouping them by date (shown in pic 3). I never wanted that nor do I need it. I want to see them all in a list in chronological order regardless of date.
The new version just doesn't work for us, and I hope these issues are addressed before we are forced to switch.
