This incident has been resolved.

We're aware of delays affecting emails sent from SuperOffice - including login confirmation codes, account activation links, password reset emails, and CRM mailings - to recipients whose email is hosted on Microsoft 365 or Outlook.com (Outlook, Hotmail, Live addresses). This is caused by a known issue on Microsoft's side that is temporarily limiting how quickly they accept incoming mail from external senders, including us. It is affecting many senders across the internet, not just SuperOffice. What this means for you: Affected emails are delayed, not lost - our email provider automatically retries delivery over the following hours. If you're waiting on a confirmation code or activation email and it hasn't arrived after a few minutes, please wait and try again shortly rather than requesting a new one repeatedly, as this does not speed up delivery. No action is required on your end. We are actively monitoring the situation together with our email delivery provider and will update this page once Microsoft resolves the underlying issue.

We are continuing to monitor the scope of this issue.

We've identified the cause: this is a confirmed issue on Microsoft's side affecting delivery to Microsoft 365 / Outlook.com mailboxes, tracked internally by Microsoft as incident EX1467029. We've verified it affects multiple independent SuperOffice email systems (login/confirmation codes and Service/CRM emails) in the same way, confirming the cause is on Microsoft's end, not ours. Affected emails are delayed, not lost, and will be delivered automatically once Microsoft resolves EX1467029. No action is required on your end.

Microsoft has confirmed the cause: an anti-spam detection model in Exchange Online was incorrectly enforcing throttling against a subset of legitimate senders, including SuperOffice, causing "Server busy" delays for messages sent to and from external domains. Microsoft is rolling back the affected model and adding impacted sending IPs to an allow list as an interim mitigation. They estimate this rollout will complete within the next 30 minutes (as of their last update at 2:26 PM GMT+2), with their next update due by 4:30 PM GMT+2. We expect email delivery to Microsoft 365/Outlook.com recipients to recover as this rolls out. No action is required on your end — delayed emails will continue to be delivered automatically. We'll update this page once we see delivery return to normal or once Microsoft confirms resolution.

Email delivery to Microsoft 365/Outlook.com recipients has returned to normal. We've confirmed no new "Server busy" (4.7.500) delivery failures for over an hour, and previously delayed emails are now being delivered successfully. This aligns with Microsoft's mitigation of the underlying anti-spam enforcement issue (EX1467029). We consider this incident resolved. If you continue to experience delivery delays to Microsoft 365/Outlook.com addresses, please contact support.

Microsoft has confirmed that their Microsoft 365 service degradation has been resolved. However, we have continued to receive reports of SuperOffice for Outlook remaining in a loading state in Microsoft Outlook and Outlook on the web, including new reports this morning. Our investigation now points to a brief, intermittent issue on SuperOffice's own infrastructure serving the add-in, rather than the previously suspected Microsoft service degradation. The issue appears to have resolved itself for affected users, but we are continuing to investigate the exact root cause. If you are still experiencing a loading screen, closing and reopening the SuperOffice for Outlook add-in should resolve it as a temporary workaround. We will provide a further update once we have confirmed the root cause.

We have identified the cause of SuperOffice for Outlook remaining in a loading state and have taken corrective action. The service has been stable for the past hour and we are continuing to monitor closely. We will provide a further update once we are confident the issue is fully resolved, or if the situation changes.

We have seen no new occurrences of SuperOffice for Outlook remaining in a loading state since corrective action was taken, and feedback received from customers has been positive. Based on this, we consider this incident resolved. If you are still experiencing this issue, please contact SuperOffice Support so we can assist you directly.

We are investigating an issue where SuperOffice for Outlook app may fail to load in Microsoft Outlook and Outlook on the web, causing the add-in to remain in a loading state. Our investigation indicates that this may be related to an ongoing Microsoft 365 service degradation currently reported by Microsoft. We are actively monitoring the situation and assessing the impact on SuperOffice for Outlook users. We will provide further updates as more information becomes available.

We have investigated reports of SuperOffice for Outlook remaining in a loading state in Microsoft Outlook and Outlook on the web. Based on our investigation and information published by Microsoft, the issue appears to be related to an ongoing Microsoft 365 service degradation affecting Outlook and related services. We have not identified any issues within SuperOffice services. Microsoft is actively working on the incident and users may experience recovery at different times as the situation improves. For the latest updates, please refer to Microsoft's service health information. We are monitoring the situation and will provide further updates if new information becomes available.

All evidence gathered so far continues to point to an ongoing Microsoft 365 service degradation as the cause of this issue, and we have not identified any related problems within SuperOffice services. As this is not something SuperOffice can act on directly, we are monitoring Microsoft's incident status and its impact on SuperOffice for Outlook. We will update this page with the latest information as it becomes available, or once the issue is confirmed resolved.
