Issue Status: RESOLVED

Issue Description: Users may be intermittently unable to search for messages within Outlook on the web.

More info: Affected users may intermittently encounter an error message saying “Sorry, something went wrong. Please try again later.

Final Update: 07/02/2024 08:28:00 AM – The targeted fix has finished deploying and Microsoft have monitored telemetry to confirm the impact is resolved.

Scope of impact: Some users searching within Outlook on the web may be intermittently impacted.

Root cause: A latent configuration issue is causing a subset of infrastructure that facilitates search functionality to intermittently perform below our managed service threshold during periods of planned service updates, which is resulting in impact.

Next steps: Microsoft are investigating the underlying cause of the configuration issue to help prevent similar impact during periods of planned service updates in the future.
