Big news! Azure AD now allows guest users with any email address


28, 2019

Back in 2017, Microsoft first announced the general availability of Azure Active Directory (Azure AD) B2B collaboration which allows you to work closely with people outside the organization giving them access to documents, resources, and applications while maintaining complete control over your organization data. In addition to supporting Azure AD and Microsoft accounts, Microsoft announced the support for Google accounts last year. Today, Microsoft is taking it to the next level by adding support for any email account. The new preview of email one-time passcodes (OTP) feature enables B2B sharing with anyone with an email account.

Here’s how the feature works:

  • With one-time passcode authentication, the guest user can redeem your invitation by clicking a direct link or by using the invitation email. In either case, a message in the browser indicates that a code will be sent to the guest user’s email address. The guest user selects Send code:
  • A passcode is sent to the user’s email address. The user retrieves the passcode from the email and enters it in the browser window:
  • The guest user is now authenticated, and they can see the shared resource or continue signing in.

After successful authentication, the session will only last for 24 hours, after which guests have to re-authenticate with a new email OTP.
