I had my departments outlook exchange email setup on my phone using K9 email. When my department switched to Zimbra, I was told the only change to make was the Zimbra's server address. I made the change and now I get "Cannot connect to server (IOException) error.
My username and password did not change, so I don't know what I'm doing wrong. Any suggestions? They haven't disabled the Outlook acct yet so I can still retrieve my email, but eventually I will have to change over.
