Thank you for the welcome.
After many, many hours and some help from DLink support over days of waiting for their reply, I was finally able to get into the setup through Internet Explorer. Once I figured out the credentials the pop up wanted, that became a huge plus. However, even after putting in the setup info with email address etc., I was still getting an invalid username/password, until I read the above post about turning on less secure apps. Once I did that, it was a 10th of a second compared to, maybe 20 hours of trying to figure it out.
I'm just not sure if I have to keep the less secure app on all the time, or now that I am set up if I should turn off the less secure app.
Thank you so much for wanting to help me as I greatly appreciate it.
