The Outlook SMTP server may replace the display name in your From: address with the name you registered with your Microsoft account. Enter it and check the box to save it in the password wizard. Change the Hotmail email address to the email address in Tools -> Account Settings -> Hotmail -> email address, Tools -> Account Settings -> Hotmail -> Server Settings -> Username, and Tools -> Account Settings -> Outgoing Server (SMTP) -> Hotmail -> Edit -> UsernameĮxit Thunderbird and restart. In Thunderbird delete the saved Hotmail passwords using Tools -> Options -> Security -> Passwords -> Saved Passwords. It will ask you what to do with Hotmail mail (either put it into the inbox or in a separate folder). Use the old username when creating the new account. Then click the gear icon in the upper right corner, click More mail settings and Rename your email address. You can add this email address by clicking the gear icon in the upper right corner, click More mail settings, Account details, and then select security info. That email address may be needed for you to confirm your changes (prove its you who is doing that). If you haven't already specified an alternate email address that can be used to get a new password if you forgot yours, do so. If you want to switch to a email address first switch to webmail.

You don't need to make any changes in Thunderbird since uses the same POP and SMTP servers as Hotmail. If you already have a Hotmail account that works with Thunderbird you can switch between the Hotmail and Outlook webmail using the gear icon in the upper right corner (of their web page). Microsoft is slowly replacing Hotmail webmail with webmail. If an account suddenly stops working take a look at Outlook down detector You don't need to do this using a browser, Thunderbird will login to Hotmail/Outlook whenever it checks for new mail. You need to login periodically to keep Microsoft from disabling the account.

Normally you'd only use it if you're behind a firewall that prevents you from accessing the POP server or you need to download the contents of the Spam folder. However, the webmail extension is slower, harder to configure and may break (requiring you to get an updated add-on) whenever the web page changes. You can still use the webmail extension and its Hotmail add-on. If you run into performance problems try using the server for POP or IMAP and server for SMTP instead.
