Mac (Mojave) Mail- Error Unknown Destination

Started getting password errors for one of our sbcglobal email addresses.  I created a secure mail key (I have done this successfully for our 4 other accounts on other computers running different OS and have had no issues), but on my Mac (Mojave) laptop, there is no place to enter the password in the Server Settings window.


When I click "get mail" a blank window opens that I need to enter the password.  This results in an att.com log-in window that appears to be a main att web window and it wants me to enter my credentials.  Since it looks like a web-page, I enter my Web Page credentials.


This results in an "Unknown Destination" error (or just blank screen).


I've tried entering the secure mail key in Keychain Access but that did not work.  When I try to get to the server settings in Mail>preferences>accounts, there is no field to enter any log-in information.

I can access the email account via the web server using the normal password.

Not sure what happened to the images I posted with the text.  I'll try again to post them in this reply.  It shows the examples of what I was running into.

These are the windows that pop up within my Mac Mail program...

Hey there @mhawker we are here to help you get access to your email.

 

We would need to be sure your Mac is directing to the correct destination.

  1. In the Apple Menu select System preferences
  2. Then Internet Accounts
  3. Choose Yahoo
  4. Put an email "@" currently.com together
  5. Yahoo will redirect you to an AT&T Login
  6. Enter your email and password for your AT&T account
  7. It will do an OATH authentication and setup for your account on Mac using OATH

You can find more Troubleshooting email steps, to further check any app or common error messages. There is even a tool to help set up emails.

 

Let us know if this has helped!

Thanks Megan.  I appreciate the reply.


Coincidentally, I was about to post my findings from this morning.  I tried again using the same steps I had been using and it worked this time.   

All the best.
