About this tag
The office update tag covers recent Microsoft 365 Apps and Classic Outlook changes, with a focus on a June 29, 2026 fix for missing Copilot buttons.

The coverage also considers fallback options such as new Outlook, Outlook on the web, or a temporary Current Channel rollback when the repaired buttons do not return.
