Microsoft 365 has experienced another outage, which is impacting search features in several services.

Microsoft experienced another outage that impacted the search functionality of various Microsoft 365 services, including Outlook on the web, Exchange Online, SharePoint Online, Microsoft Teams, and Outlook desktop clients. The company acknowledged the problem on April 24th and stated that it was actively seeking short-term and long-term solutions to resolve it. On Tuesday, Microsoft confirmed that the search functionality had been restored for some users, but the service was not yet fully restored. Microsoft provided updates on the issue on its Microsoft 365 Status handle on Twitter, and said it had developed a fix for the issue and was validating it before deploying it.

Microsoft has faced four service disruptions this year, all of which have impacted some of the Microsoft 365 services. Last week, Microsoft 365 web applications and Teams were inaccessible to users, but the services were subsequently restored after Microsoft investigated the errors within the caching infrastructure and high CPU utilization on components that process backend navigation feature APIs. In February, a global outage occurred, preventing users from accessing emails on Outlook or using Teams. In January, a global outage affected Microsoft Exchange Online, SharePoint Online, OneDrive for Business, Teams, and Outlook.
