ISSUE

After you install Windows 10 update KB5008212, or upgrade to Windows 11, recent emails may not appear in search results. 

This issue mostly affects users with POP, IMAP, and offline Exchange accounts due to search using the local Windows Search service to index email. Microsoft 365 hosted email and connected Exchange accounts use Service Search which is not affected by this issue.
