I use Outlook 2010 to process several email accounts. I noticed a few days ago that a couple of the email accounts had vanished from the list. I also noticed that one still present was not sending or receiving. I tried re-entering the password and when that didn't work I deleted and re-entered the account. It tests fine but the test message never shows up in my Outlook inbox. It does show up immediately on my phone when I check my mail there.
