Classic Outlook clings to stale search results as Microsoft works on a fix
Moved messages linger and throw errors when clicked, leaving Windows Desktop Search as the workaround
Microsoft is urging Outlook users to switch from the classic version to the newer version, but a search bug may be hindering the adoption of the older client. The issue causes results to fail updating after mailbox items are moved or modified, with Microsoft offering a workaround to redirect affected users to Windows Desktop Search.
Classic Outlook is struggling to update when items are moved into different folders, and changes to categories or read/unread status may also be impacted. The problem is confined to Server Assisted Search for mailboxes in online mode. Microsoft is addressing the issue with a workaround involving a registry change to switch Classic Outlook back to Windows Desktop Search.
Microsoft plans to phase out Classic Outlook, with affected enterprise users set to be moved to New Outlook by default starting in 2027. Classic Outlook will still be supported until at least 2029, but administrators can prevent the migration. Despite Microsoft's efforts, the Classic Outlook still suffers from bugs, such as the borking of the Quick Steps function, and an issue preventing some users from accessing voicemail audio attachments, which was addressed in a recent update.
