To follow up:
Clicking on the "1 New Message in InBox" link in the main UI takes me to this page:https://account.live.com/summarypage.aspx
rather than my inbox.
Why doesn't aMSN take me right to my inbox, as it used to? Is this a server-side MS issue or a bug I should report at SF?
Also, I'm sorry to harp on this, but cranky RTFM N00B replies aren't helpful, especially when I've already searched the forums...and especially considering that aMSN makes use of some of my code in the Mac version! Really, now.
