Thank you for your suggestions. I can access my email account from my mac, but not my phone. I have 3 accounts....one is icloud, one is gmail and the one I'm having trouble with is my ameritech.net account. To get to my ameritech account I go to google, then yahoo mail, on my phone I can access my account, not just straight to my email accounts. However, I went to settings yesterday, and removed the ameritech account from my emails in hopes of adding it back and still today, even after double checking and going to yahoo mail and that letting me access it on my phone, I still cannot add it back as another email account. When I log in and put in the password, it says:
Settings
Mail
Accounts
Add account
Choose yahoo
Sign in username
I enter my password
redirected to a different screen with the AT &T logo but with Yahoo at the top
Loginprodx.att.net
Sign in now....again because it's a different looking screen
user name
password
Next screen says in small red letters at the top. Unknown destination
At least I can access my ameritech.net account from my phone but with 3-4 extra steps instead of just tapping on the envelope.
Any more ideas? Thank you so much for your help.
