The Outlook Add-In, while containing many features I like, crashes at least twice per week for me. It requires having to disable, then re enable the add-in. It's too useful to not do it, but it's a tad frustrating. I'm also not too happy that when I add tasks in my blackberry, they don't tie in with the add-in at all. It does not categorize them per the add-in and I have to go in and do this when I get back to my desktop. That's blackberry's fault, not the add-in, but frustrating nonetheless. Overall, I'm happy with the add-in's features.
