🔍Outlook Classic Search Bug: Microsoft's Hotfix Escalation
Outlook Classic's Search Bug: Microsoft's Fix Timeline
TL;DR
Outlook Classic users face a search bug that fails to update results after changes. Microsoft is working on a fix but no ETA. Classic Outlook is being phased out by 2027.
Microsoft is scrambling to fix a search bug in Classic Outlook that fails to update results after mailbox items are moved or changed. The issue affects Server Assisted Search for mailboxes in online mode. As a workaround, Microsoft suggests disabling server-assisted searching via a registry change, forcing Classic Outlook to rely on Windows Desktop Search instead. A fix is in progress and has been escalated as a hotfix to the Outlook team, but there's no ETA for when it will be available. Meanwhile, Classic Outlook is on the way out, with Microsoft planning to phase it out by 2027. Existing installations will be supported until at least 2029, but the opt-out phase for Classic Outlook will kick off in 2027, moving affected enterprise users to New Outlook by default unless administrators block the migration. Users will still be able to switch back to Classic Outlook until the cutover phase removes this option.

Why It Matters
