Today, the Outlook web client is refreshing itself as soon as I select an email to read, as if selecting an email is issuing a postback. This clears the reading pane. It is happening on two machines. It began yesterday evening but I had other things to do and was not concerned. It basically makes the site useless. I can get by with the Mail app or Outlook desktop, so it is hardly a show stopper. Just wondering if others are having issues.
