I tried to log into Microsoft’s free email Outlook.com to check the display of HTML emails, but they handle so many domains that I forgot my login email address (Microsoft account).

Domain names handled

• outlook.jp
• outlook.com
• hotmail.co.jp
• live.jp

So I wouldn’t have trouble even if I forgot, I set up aliases for all domain names with the username I use frequently on the account alias management page.

That’s all from the Gemba.
