In this article, we will explain how to re-enable the disabled or grayed out Outlook advanced search functionality using Windows Registry. The steps are simple and will enable your search options immediately.
Enabling Advanced search in Microsoft Outlook
Advanced search gets disabled automatically if you have disabled indexing in Windows. We can safely enable indexing to enable Outlook advanced search. Hopefully, Outlook advanced search will be available now. You can do the advanced search again within your inbox about any email, any subject, any sender, or any receiver. Apply the steps and get your advanced searches back in Outlook. Thank you.
