Title: Some users may be intermittently unable to access their Exchange Online mailboxes via Outlook on the web User impact: Users may be intermittently unable to access their mailbox via Outlook on the web. More info: Other connection methods such as the desktop clients and mobile apps are unaffected. Current status: Our investigation into identifying the root cause of this impacting event is taking longer than expected. We've identified one potential cause that requires further review over a period by validating usage patterns outside of business hours to verify our leading theory, considering at this time our telemetry suggests the impact has subsided. At the same time our investigation into other possible root causes through review of feature configurations and logged errors is happening in parallel. Scope of impact: This issue may affect users that are based in North America and are attempting to access their Exchange Online mailbox from Outlook on the web.

We want to inform you that the Secure Email Threat Defense (SETD) service is currently unavailable due to an ongoing outage in a cloud service provider in the UAE region. As a result, SETD is temporarily unable to scan emails for threats, and users are unable to log in to the SETD portal. Email delivery is not impacted for the users. The Cisco team is actively monitoring the situation with our cloud service provider and will restore the service as quickly as possible. In the meantime, please be aware of the following impacts: • Emails will not be scanned by SETD, which may increase exposure to phishing, malware, and other threats. Access to the SETD portal is unavailable for reviewing threat reports, managing configurations, or accessing quarantined emails. • There may be a delay in threat detection and response until the service is restored. • A backlog of unscanned emails may occur and require additional processing once service resumes. We apologize for any inconvenience this may cause and appreciate your understanding. If you have any questions or concerns, please contact our support team. Thank you, Secure Email Threat Defense Team .:|:. .:|:. Cisco
