Frequently Asked Questions
Why did Microsoft remove Smart Lookup without notice?
Microsoft regularly updates its Office 365 applications, often removing or consolidating features based on telemetry data, redundancy, or to make way for newer AI-driven tools like Microsoft Copilot. They have not provided a specific public explanation for removing Smart Lookup.
Can I bring Smart Lookup back to Microsoft Word?
No. Because Smart Lookup relies on Microsoft's cloud-based services, you cannot restore it once it has been discontinued on the server side, even if you try to downgrade to an older version of Word.
Does the 'Search' function do the same thing as Smart Lookup?
Yes, the standard 'Search' function serves as the direct replacement. It provides web results and basic definitions through Bing, although the interface and the exact depth of information presented may differ slightly from the old Smart Lookup pane.
How can I look up definitions without leaving Word now?
You can highlight a word, right-click, and select 'Search', use the built-in Thesaurus under the Review tab, or install a free Dictionary Add-in from the Office Add-ins store located under the Insert tab.
