What's so great about Outlook? I don't get it. Tips?

[coip]

I've been using Outlook exclusively for nearly a month now. I like it. Very useful. It's really easy to keep track of all my email addresses, calendar appointments, tasks, etc. I especially like how great the built-in Office previewer is, for previewing email attachments such as Word, Excel, etc. Very good, which makes sense, since Outlook is part of Office, but still!

There are some tiny issues, mainly about syncing: for instance, my People tab in Outlook is not as well synced as my People tab in Outlook.com. The other big problem is that there are still missing emails, most noticeable when I search for something (I would love to see the search results get revamped; it's not easy to find stuff right now. They need to Bing-ify this and add filters, etc.), and syncing when sending emails occassionaly has problems in that it will send but not show up in my sent folder, or, more common, it will send it but leave an unsent draft on the server, which is weird.
