Microsoft Outlook email searches are broken again in Windows 11

Microsoft is investigating an issue that prevents Outlook search from displaying recent emails in the Windows 11 desktop application. 

The issue affects offline POP, IMAP, and  Exchange accounts because of the search feature. of Outlook uses the Windows local search service to index emails. 

Microsoft 365 and connected Exchange accounts are not affected because they use the search service, which is not affected by this issue. 

"When searching in Outlook Desktop on Windows 11, the most recent emails may not show up in  search results," Microsoft said. 

"If you check the Windows indexing options in  Control Panel, indexing may be  slow or interrupted." 

The company is currently working on a fix for this known issue and has shared a temporary fix to affected customers until a resolution is available. 

Microsoft recommends Windows 11 users to minimize Outlook search errors by turning off Windows Desktop Search and switching to Outlook's built-in search engine as a solution.
