March 26, 2026 12:05 CET Identified - Microsoft incident reference: EX1259460 Issue Description: Some users may be unable to access custom add-ins through any Exchange Online connection method. Latest updates from Microsoft: 26/03/2026 9:04:00 PM – Microsoft is investigating the possibility that incoming traffic may not be appropriately balanced throughout the affected environment while also continuing to review the previously identified exception to determine the root cause and a strategy that remediates impact. 25/03/2026 8:35:00 AM – Microsoft hasn't confirmed a viable workaround, however they have identified an authentication-related exception which may be contributing to the impact, and they are further reviewing this exception to aid in their root cause analysis. Should you wish to follow updates from Microsoft directly you may do so from the Microsoft Service Health Dashboard under ID EX1259460 https://learn.microsoft.com/en-us/microsoft-365/admin/manage/health-dashboard-overview If you are impacted by this and are unable to wait for a resolution from Microsoft, you may find available workarounds as below: Total Protection Outlook Add-in Workaround http://support.hornetsecurity.com/hc/en-us/articles/21797951259537-Manual-installation-of-the-Outlook-add-in AIRV Outlook Add-in Workaround http://cp.hornetsecurity.com/manual/en/ai_recipient_validation/t_deploy_ai_recipient_validation_add_in_manually.html April 1, 2026 10:39 CEST Resolved - Microsoft incident ID EX1259460 has been set to status "Service Restored". Below is the final status posted by Microsoft: We’ve identified that a recent Exchange Web Services (EWS) deprecation update and an Exchange Online authentication change prevented users from accessing custom add-ins in Outlook. To remediate this issue, we rolled back both offending changes and verified through service monitoring that this action successfully resolved the impact. Admins that have disabled EWS may continue to experience this issue and we recommend that admins re-enable EWS at this time. For additional guidance on managing Exchange Web Services, please refer to the following: https://learn.microsoft.com/en-us/exchange/client-developer/exchange-web-services/how-to-control-access-to-ews-in-exchange Scope of impact: Some users who are attempted to access custom add-ins through all Exchange Online connection methods may have been impacted. Start time: Thursday, March 12, 2026, at 10:04 PM UTC End time: Friday, March 27, 2026, at 1:40 AM UTC Root cause: A recent EWS deprecation update and an Exchange Online authentication change prevented users from accessing custom add-ins in Outlook. Next steps: - We’re reviewing how the impacting changes prevented users from accessing custom add-ins so we can avoid similar issues in the future, as EWS is slated to be deprecated by October 2026.

We will share updates as soon as new information is available through our joint investigation. February 26, 2026 14:10 CET Monitoring - Microsoft have deployed a fix for the issue causing Add-ins to disappear. Affected customers will need to reinstall the Total Protection Add-in through the Control Panel.
