Sending, receiving, and organizing email in Outlook.com

The most common cause for this is a bad entry in your Suggested People/Autocomplete Cache (a history of names and emails that you have used in the past).
First thing to try - Do you have a Contact entry in your People/Contacts for yourself? If not, create one using your full name and email address. (When you type on the "To" line, Outlook first looks in your Contacts for a match and only if it can't find one does it search your Suggested People/Autocomplete Cache). So this may "mask" the bad entry.
If that doesn't work, you can try clearing your Suggested People/Autocomplete Cache.
