Microsoft is investigating an ongoing issue preventing some customers from using the search functionality across multiple Microsoft 365 services.
The list of affected services includes but is not limited to Outlook on the Web, Exchange Online, SharePoint Online, Microsoft Teams, and Outlook desktop clients.
“We’re investigating an issue where users may be unable to use the search functionality in multiple Microsoft 365 services,” Microsoft tweeted earlier today.
“We’re analzying service telemetry to determine the source of impact and develop a mitigation plan,” the company added in a Microsoft 365 admin center incident report.
The company has yet to reveal if this is a worldwide issue or only affects customers from a limited number of areas.
We’re investigating an issue where users may be unable to use the search functionality in multiple Microsoft 365 services. Further information can be found under MO545600 within the Microsoft 365 admin center.

Microsoft is also working in parallel to address another issue affecting the Teams communication platform, where users are reporting seeing error screens the starting the software.
“We’ve identified that the cause of the problem and are reviewing options for development and deployment of a fix to correct the issue for all users,” the company said on the Office service health page on Thursday, April 20, when the issues first started appearing.
Microsoft is now testing two potential fixes for the Teams start-up errors, either by reverting to a previous unaffected build or developing a fix to correct this issue.
Another outage took down multiple Microsoft 365 services last week, blocking customers worldwide from signing into their accounts and seeing no web apps once in.
In some cases, banners at the top of the screen asked “new” users to contact their IT departments to help address the issue.
As it was later discovered, last week’s outage was caused by caching infrastructure performing below acceptable performance thresholds, leading to timeout exceptions within Azure Active Directory (AAD) infrastructure.
Microsoft 365 was hit by another massive outage in January after a router IP address update caused router packet forwarding issues within Microsoft’s Wide Area Network (WAN).
Update April 24, 15:40 EDT: Microsoft is now testing and validating a fix for the Microsoft 365 search issues.
We’re conducting our final testing of the fix, and additional time is needed for validation. We’ve observed positive results from an interim change, and we’re evaluating further updates to improve the experience. Additional info is available under MO545600 in the admin center.
