Having the same problem (02/11/14). Tried signing on via the normal logon screen and received another (different) screen asking for my password which, BTW, made me a bit skidish thinking someone hacked into their mail system and were trying to copy email addresses/passwords. Tried for several minutes and then, all of a sudden, voila!, I got in (yes, via the initial logon screen). Yes, it does make me think about migrating to somewhere else. I'm starting to think that they're doing sometype of system change(s) without prior user notification of said change (I used to work for IBM).
