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 are providing an update on the ongoing service disruption. The Middle East (UAE) Region (ME-CENTRAL-1) has suffered damage as a result of the conflict in the Middle East and is currently unable to reliably support customer applications. While some workloads continue to function normally, we strongly recommend customers migrate all accessible resources to other Regions and restore inaccessible resources from remote backups as soon as possible. Relevant billing operations are currently suspended while we restore normal operations in this AWS Region. This process is expected to take several months.
