How to Fix Issues with Your Outlook 2016 Search
If the Outlook search suddenly stops working, a solution is needed quickly. Often, it helps to check the index or repair the PST files. If this does not help, the problem usually lies with the program itself. Since Microsoft’s March 2018 update for Office 365, there have been consistent issues with Outlook’s search function on Windows 10. Emails retrieved via POP or IMAP accounts could no longer be indexed by the search function and therefore returned no results. A temporary solution was to switch back to the original Outlook search and disable the desktop search feature.
