Good afternoon, We are currently experiencing a service disruption primarily affecting Outlook, along with related applications. Microsoft has confirmed that users may encounter intermittent sign-in issues, including “too many requests” errors or unexpected sign-outs. They have rolled back some recent changes, but the issue is still ongoing as they continue their investigation. We know how disruptive this can be and really appreciate your patience while this is being worked on! Best regards, The Tech-Keys Team

Good morning, another update here! The service disruption affecting Outlook and related applications is continuing to improve and appears to be stabilizing. Microsoft’s changes from yesterday are having a positive impact this morning. We are still seeing some residual issues for users accessing email through the Apple Mail app rather than the Outlook app. We will continue to monitor this and share any updates as we hear them! Thank you for your patience, and we hope you have a great day! Best regards, The Tech-Keys Team
