Windows에서 개인 이메일, 일정 및 연락처 관리에 클래식 Outlook 사용
Hi, my name is Ric. You should allow Outlook to finish indexing your emails as during this process, it will not give out results. Try again once it finishes. However if it still does not work, you may need to rebuild the search index manually. You may check this guide for info https://support.microsoft.com/en-us/office/trou.... Link is in English. Please use a translator tool if needed. You can also check indexing status inside Outlook by going to File > Options > Search > Indexing Options.
