Outlook search not working

My Outlook search stopped working. There are no results for any query. There are a few suggestions online. None of them seem to work. I tried: - forcing repair of database by deleting Outlook.sqllite - turning Spotlight on and off (sudo mdutil -i on /) - adding and removing the Main Profile folder from the list of locations that Spotlight is prevented from searching Is there anything else I could try? I am running Outlook 16.56 and 16.57 on macOS 12.1. Update: I found a discussion that suggests this may be an issue with Monterey 12.1 and another one on Apple Developer forums . It seems that updating to 16.57 worked for some people there, but it did not for me.
