Monitoring

Hello,

We have verified that previously undelivered newsletters are now being delivered to Outlook users in some time intervals. However, some delivery delays are still being observed due to the ongoing Microsoft service degradation.

We are still actively monitoring the issue and the Microsoft status page and will continue to share updates as needed.

Thank you for your continued patience and understanding,
