Sending, receiving, and organizing email in Outlook.com
Thank you Emmanuel!
I did see a previous post saying they had done this and I have now done this also. Her "hot"mail appears to be forwarding to the gmail account on her MacBook. She is also running macOS Mojave 10.14.6.
I feel so bad for people who have little to no computer experience as it was not easy for me to figure out and I think I am fairly computer savvy. A waste of a good month continually trying to enter a password or reset all passwords until I finally opened her outlook account to search community questions. This isn't the easiest either, as asking the right question to get the right answer can be challenging!!
