There are two times when Microsoft asks to verify your email address: when you add an email address to your Microsoft account, and the first time you send an email from a new Outlook.com address.
When you sign up or add an email address to your account, we automatically send a request to that email for you to verify that we have the right address. To finish the process, just follow the verification link in the email.
If you need a new verification link, here’s how to get it:
Sign in to the Microsoft account website, and select Your info.
Select Manage your sign-in email or phone number.
Select Verify next to the email address, and then Send me verification email.
Spammers sometimes use automated programs to create email accounts and then send junk email to others. When you send an email message from a new Outlook address for the first time, we ask you to verify that you’re a human, not an automated program.
When you click the verification link, you're asked to type a series of random characters as shown in a picture. (You can listen to an audio file that states the characters if you prefer.)
Outlook will occasionally prompt you to verify your account again, just to make sure you're still you and your account hasn't been compromised by spammers.
