I can no longer send mail, only receive. Exchange 2007, Outlook 2007 and iPhone 5. Cannot connect to outgoing smtp. It's worked for nearly 2 years and now, nothing. Nothing changed on my end.
I connect to a secondary e-mail address using POP/SMTP to my Exch. 2007 through outlook 2007 and iphone 5. It has worked flawlessly for nearly 2 years. Now, for some reason, it has stopped working on both. I have not changed anything on the exchange server.
However, if I'm within my work wifi...it works as always. If I turn wifi off on my phone...does not work.
