In ATS' defense, they announced that this was going to happen several times over the past month via the [log in to unmask] listserv.

Apparently they updated the mail.msu.edu ssl certificate this morning. The Service Status history suggests that "Many clients will not be affected", but so far that's not my experience. Outlook users doing sends here are getting prompted to accept a certificate that can't be verified. (Checking mail doesn't seem to prompt this, but sending mail definitely does seem to be.) (Personally, I'm seeing this on a Windows 7 machine running Office 2007, all updates installed, and so far everyone that I know using outlook that I've asked has seen it. So I'd have to wonder about the "Many clients will not be affected."). One other note, I honestly don't remember seeing any sort of communication that this was happening, did I miss it? Gary
