I have not gotten my head around Microsoft's Account settings and think I might have messed things up. I created a couple of outlook.com email aliases and then opened the "Change Sign-in Preferences" section where it suggests to only allow email addresses that are monitored. So I did that and checked off the addresses that I don't monitor. I realized later that I would like to reverse that action but find that the aliases are no longer listed and I cannot remake them because Microsoft says that they are taken. Is there anyway to reactivate the aliases that I checked off in the "Change Sign-in Preferences" section?
