We are continuing to investigate this issue.
We are actively engaged with our co-location partner to restore connectivity at Equinix FR5 location in Frankfurt, DEU. Since our last update, we have made incremental progress to restore safe access to the affected area at the Equinix FR5 location in Frankfurt, DEU. In parallel, we have prioritized the order in which critical and high-priority racks will be restored, as part of the mitigation efforts. Based on our current assessment, full recovery is not expected in the near term and may extend beyond today. AWS Direct Connect connections at this location remain impaired. Customers with connections exclusively at this location will continue to experience packet loss. Customers with multi-site or redundant configurations across other Direct Connect locations remain unaffected. For a workaround, impacted customers who have the option available to failover to VPN are recommended to do so. For customers using Direct Connect gateway and Transit Gateway, we recommend creating a AWS Site-to-Site VPN and attaching it to your Transit Gateway, refer to steps <a href="https://aws.amazon.com/premiumsupport/knowledge-center/dx-configure-dx-and-vpn-failover-tgw/">here</a>. For other customers we recommend establishing an AWS Site-to-Site VPN as a temporary backup path, refer to steps <a href="https://docs.aws.amazon.com/vpn/latest/s2svpn/SetUpVPNConnections.html">here</a>. We continue to closely track progress and will share an update by August 16 3:30 AM PDT, or sooner as new information becomes available.
Title: Users may be unable to sign in to OneNote using iOS devices User impact: Users may be unable to sign in to OneNote using iOS devices. More info: Impact is specific to users with OneNote build 16.112.717.0 or higher. Whilst we work on remediation, impacted users may be able to utilize OneNote on the web or remove Authenticator so that authentication falls back to the in-app webview. Users may also be able to sign in to any other Microsoft 365 apps first (e.g. PowerPoint), then attempt to sign in again in OneNote. Current status: We've identified that a code change included in OneNote builds 16.112.717.0 and above, designed to change how authentication requests are routed, introduced an issue with OneNote iOS Authenticator broker sign-in and is causing impact. We're deploying a code fix to correct this issue and expect that it'll complete deployment by the time of our next update. Scope of impact: Any user attempting to sign in to OneNote build 16.112.717.0 or higher using iOS devices is impacted. Start time: Monday, July 20, 2026, at 4:36 AM UTC Root cause: A code change included in OneNote builds 16.112.717.0 and above, designed to change how authentication requests are routed, introduced an issue with OneNote iOS Authenticator broker sign-in and is causing impact. Next update by: Tuesday, August 18, 2026, at 6:00 AM UTC
We're continuing to investigate an issue affecting a subset of channels with custom message retention settings. Custom channel retention settings have been restored for affected customers. Custom retention jobs remain on hold for some customers as we work to fully resolve the underlying cause regarding the custom message retention issues.
