Title: Users’ push notifications fail approximately five percent of the time for any Exchange Online connection method

User impact: Users’ push notifications fail approximately five percent of the time for any Exchange Online connection method.

More info: Most push notification failures are occurring on Outlook for iOS devices.

Current status: We suspect that a code regression was introduced by an ongoing deployment. We’ve halted the suspected problematic deployment and initiated the process of reverting the change to remediate the impact, which could take two days to complete. We anticipate having a better understanding of the root cause and the timeline for impact remediation by our next update.

Scope of impact: Any user may be impacted.
