Sending, receiving, and organizing email in Outlook.com

The weird address is ...
Does it look like outlook_[long series of letters and numbers] @ outlook.com (without the spaces)?
If so, this is a placeholder email that Microsoft created when you used a non-Microsoft email address (like Gmail) as the "Account ID" for you new Microsoft/Outlook account.
It won't let me sign into my real outlook account, so I can't access email, contacts, calendar.
Were you ever able to sign-in to your "real" outlook account? One that had your real user name and ended in outlook.com ?
If you created your Microsoft Account using a non-Microsoft email address (like Gmail) as the Account ID, then that is the address you should use when trying to Sign-In to your Microsoft account.
Microsoft says it doesn't exist, but it shows up as the email folder when I log into Outlook.
I doesn't exist. It's just a placeholder "alias" for your account. But you should not normally see it.
Using a Private/Incognito browser session can you open and sign-into this page? https://account.live.com/names/manage Do you see a non-Microsoft email address (like Gmail) as the Account ID? Are there any other aliases listed on that page?
