Outlook 2007 won't connect to Exchange 2013

I have a Exchange 2013 server and Outlook 2007 clients.  On all the clients I have to tell it to use the Exchange server as a proxy.  That works on all but one client that worked until today.  Not it says "couldn't open your default folders.  Exchange server is unavailable."

With Exchange 2013, it is a lot tougher to manually configure outlook to connect to it.  That is why having a properly configured and working autodiscover system is vital.  It sounds like your autodiscovery isn't setup right.  Have you run the office365 based autodiscovery tests against your exchange 2013 server?  Alos, if something recently stopped working, have you recently decommissioned an old exchange server?  Many times there are outlook clients still connecting through the old server to get to their mailbox on the 2013 server and you don't find out about it until you turn down the old server.

Ya, the autodiscover works - all the other stations work.  Turns out this user just installed Firefox.  We uninstalled it and her Outlook started working again.  Doesn't make any sense.

Found Firefox to be the problem.
