I'm setting up Office 365 with syncing to local folders for those that have a workflow that requires Explorer instead of navigating files and folder in SharePoint/Teams. I'm also testing how to use ONLY the online version of Office.

I found that I can right click an Office document and select View online to open the document in the applicable online Office app. This is not horrible, but complete application association would be better. Does anyone know how to set onine Office apps as the default app for Office files? Even an affordable third party app?
