MoonSong, on another thread a user had a suggestion that might help.
First, set up a dummy account and log in using that.
Then add your Windstream account.
Another option, perhaps better, is to ask your Windstream people for the exact server settings. And then do a manual setup.
I have another email account on Gmail, but it's not the one people know and use....it's just one I've had for a few years. After I couldn't get my Windstream account to work, I tried the Gmail just to see what happened and it works fine. So it's as though my NOOK can't communicate with Windstream somehow. I have talked to Windstream tech support, manually set up the email account with their settings and still nothing. Very frustrating, and I certainly don't want to change all my email accounts and addresses to Gmail just because of the NOOK. Appreciate your advice. Will try anything to get this to work.
