Re: Poorly designed application
True.
I find writing simply and clearly difficult. My sense is by no means uncommon.
As for reinventing the wheel: point taken.
It would help if people criticising posts actually read and understood the post they are criticising, rather than criticising what they think they read.
Both the Exchange Server and the Outlook client have a lot of knobs to twiddle, which is good. On the other hand, I don't think anyone would say they are unimprovable. Microsoft claim to put a great deal of effort into making their end-user software easy to use, but their efforts don't seem to be particularly effective in this area. The end result is that users can deploy a foot-gun with depressing ease.
