Hi. I need some help or opinion from you guys, maybe you can help me. So users in the company that I'm working from was using Outlook 2007 and saving their emails locally via pst file on their computers. I upgraded their Outlook to 2021 version, but there is a problem, the search function was not working. It's showing no results. I already rebuild the Index, edited the registry, searched and installed updates, and did everything I could find on the internet but nothing is working. Maybe you can help me guys, thanks.
