I'm still getting the error message, "Couldn't Open Connection to Server". No matter how many of these forums I follow, my phone will simply NOT add my optonline emails. They used to be on this phone, but they were acting up so i was told to remove them then add them again and that was the last time I was able to see emails on my phone.

In response to the problem of “cannot get email set up on a new Android phone”: I received the exact same message of “couldn’t open connection to server” even after following instructions. Solution for me was to enter mail.optonline.net for BOTH the incoming & outgoing servers. I had successful results afterwards.
