    This incident has been resolved and 2FA codes can now be sent to a Microsoft email domain as an alternative email method

  • Update
    Update

    We have discovered that customers are not able to send emails to Microsoft email domains e.g. outlook.com, live.com, hotmail.com, msn.com. We are working with Microsoft to resolve this.

  • Update
    Update

    We’re continuing to actively work on the issue affecting email delivery and authentication for Microsoft domains (e.g. hotmail.com, live.com, outlook.com).

    At this stage, there hasn’t been a significant change, and users may still experience issues with receiving authentication codes or using Microsoft 365 SSO.

    As a reminder, we recommend using an authenticator app (such as Google Authenticator, or Authy) for login security, or using a non-Microsoft email address for your alternative email where possible.

    We understand the ongoing impact this is having and appreciate your patience while we work towards a resolution. We’ll share further updates as soon as we have more progress.

  • Update
    Update

    We’ve recently been advised that Microsoft has placed restrictions on our emails due to spam-related concerns.

    As a result, authentication and email delivery involving Microsoft domains such as hotmail.com, live.com, outlook.com, and variants are likely to be temporarily unreliable or blocked.

    We would not recommend using Microsoft 365 SSO either right now, as it could lead to ongoing login and verification issues for our users. In the meantime, we recommend either:

    • Using Google authenticator, Microsoft Authenticator or Authy app for login security, or

    • Switching to a different email domain other than Microsoft domains for your alternative email


    We understand this isn’t ideal, and we’re continuing to monitor and work on this to restore 2FA services to normal.

    We are still working on a fix and we recommend not using @hotmail.com or live.com as alternative email addresses at this time.

    Some Core users are unable to log in via 2FA using email; please contact Support for a manual reset to use the Authenticator app instead.
