I cant get my mail since upgrade saying login failure. I havent changed my password and it wont let me in
I cannot get my mail since installing High Sierra upgrade; I'm getting login failure saying my msn account password is invalid. I've tried my msn password as well as Outlook password and nothing is working. Back in 2010, the me.com always pushed my msn mail to my computer. There is Firevault on this iMac. Suggestions?
iMac 27", macOS 10.13
