Just plain sucks.
When opening a thread, it automatically jumps to the latest conversation in the thread - NOT WHAT I WANTED TO DO - I want to go to the conversation I selected,without having to browse for it again when it opens the thread - Very non-productive. Overall it looks like MS tried to imitate some of the gmail features, and then in true MS fashion, went overboard and made it difficult to use. And finally - this has been an issue for a long time - Why are reminders on Meeting notices set to the Sender's prefernce? I want them to default to MY Preference. I could care less how many minutes/hours/days the sender wants a reminder - I only care about when I need to be reminded so why can;t my default be set when i accept a meeting rather than accepting the Sender's settings? Also, new interface makes it hard to tell what day is highlighted in the calendar.
