I've been using Windows Live / Hotmail / Outlook-online some, and it's pretty good. One downside is that you can't "pop out" a window like when you create a new e-mail (like you can in Outlook client and gmail).
Anyway, I then set up Outlook client (Office 2010) on my PC, and sync'd up to Personal Hotmail-Live.com\. This seems to be working.
A couple of questions
- should I expect full sync between Outlook client and Outlook online ? Does this include e-mail rules set up on either Outlook client or Outlook online ?
- I've tried Outlook online before and gave it a good try, but not being able to "pop-out" a window was a fatal flaw to me. That's what Outlook client does, and gmail can do this, but as far as I can tell, you can't do it in Outlook online.
