Outlook for Mac 16.113 Search not functioning in Legacy View

Your testing isolates the problem: search works in new Outlook, but not in Legacy, and rolling back from 16.113 to 16.112 or 16.111 did not restore it. That points toward the Legacy profile or Spotlight integration rather than the application build alone. Run Microsoft’s OutlookSearchRepair utility, confirm the Outlook profile and its parent folders are not excluded under Spotlight Privacy, and verify the profile name contains no special characters. Then use Outlook Profile Manager to create a test profile and add the mailbox without deleting the profile. Allow indexing to finish before testing. If search still fails only in Legacy, use new Outlook as the workaround and report it through Help > Contact Support or Help > Feedback with the macOS version, Outlook build, account type, and UTC reproduction time. For Exchange Online mailboxes, Legacy Outlook support ends in October 2026, so migration should be part of the resolution plan.
