Backup operations remain healthy, with success rates staying high across all services and regions following the recent changes. Work on the EWS to Microsoft Graph API migration is ongoing, and our R&D team continues to monitor for any further issues.

As of 8/14, we identified a delay in our async job processing. We have found that the async jobs are still processing, yet at a slower rate. This delay in processing will impact your ability to create groups, build reports and Magnus 911 cards. We have taken the steps to allow the syncs to process, and we are actively monitoring this issue. We appreciate your patience and will provide an update as soon as the async jobs are processing at the expected speed.

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.
