Microsoft Email Delivery Issues (@outlook, @hotmail, @live, @msn and custom domain emails hosted on Microsoft)
Updated at 19 May 2026.
Urgent Action Required for Users with Microsoft-Hosted Emails.
Please be advised that our automated email service is currently experiencing severe delivery issues to all email addresses hosted by Microsoft. Due to recent aggressive filtering policies by their Exchange Online Protection (EOP), our mail delivery server has been blocked by Microsoft. As a consequence, our system is unable to send any notifications, password resets, or activation emails to accounts ending in @outlook.com, @hotmail.com, @live.com, @msn.com, or indeed any custom domains hosted by Microsoft.
To ensure uninterrupted service, please follow the guidance below based on your account status:
- For Prospective Users (Before Registration): Please do not use a Microsoft-hosted email address to register your account. You will not receive the essential activation link. Kindly use an alternative email service provider, such as your corporate email, Gmail, etc. to complete your registration.
- For Existing Registered Users: If your profile is currently linked to an Outlook or Hotmail address, please log in immediately and update your primary email address. You can change this by navigating to your User Settings -> Preferences -> Emails page. Failing to do so will result in missing critical repository updates, CI/CD pipeline failure logs, and Merge Request notifications.
We are actively working to appeal this block with the Microsoft Postmaster Centre. We sincerely apologise for any inconvenience caused and appreciate your prompt cooperation in updating your contact details.
