Status Service Degradation Impacted services Microsoft 365 suite Title: Some users may experience latency or intermittent failures fetching user contacts in multiple Microsoft 365 services User impact: Users may experience latency or intermittent failures fetching user contacts in multiple Microsoft 365 services. More info: Affected services and scenarios include: - Microsoft Teams users are unable to fetch user's regional and language settings using the Profile API - Exchange Online users experience latency or 503 "Service Unavailable" errors when attempting to view contact information in Exchange Online. Current status: We've validated that a change implemented to the queue for fetching contact information is resulting in a spike in processing errors, as our service infrastructure is unable to handle the influx of information only going to one specific portion of infrastructure for processing. We've implemented an Enhanced Configuration Service (ECS) change to spread the service load and reduce latency for affected users. We're testing this ECS change with a subset of affected users, and we aim to provide a timeline to mitigation as one becomes available. Scope of impact: Users may experience latency or intermittent failures for user contact fetching across multiple Microsoft 365 services. Root cause: A change implemented to the queue for fetching contact information is resulting in a spike in processing errors, as our service infrastructure is unable to handle the influx of information only going to one specific portion of infrastructure for processing.
