the only reason Im still paying for M365 is that my grandpa can't use anything else than MS Word, despite of all the awful changes MS made to its UI thought out the years. Old people stubborness can be interesting. Maintening that subscription is a pain, as MS occasionally change default save location to SharePoint. I'm the sole admin and I've never touched any thing.
