Same problem here with MBP 2016 and Monterey 12.1, Outlook version 16.56 on 365 license. I have tried all the solutions mentioned online (delete/recreate Outlook profile, add/remove email folder from Spotlight search. rebuild index by deleting Outlook.sqlite file, etc) nothing seems to work. MS says it is a bug and they have no estimated time to resolution.
