How do I delete the Conversation History folder on Office 365?

I’d like to know how do I delete the Conversation History folder on an Office 365 account?

I do not use Skype for Business, do not even use Outlook (I access the account for macOS Mail) and the folder is empty. Yet, I can’t delete it from the web (the option is just greyed out) and on Mac it gives me the following error:

The operation couldn’t be completed. (MCMailErrorDomain error 1030.)
The server returned the error: The operation couldn’t be completed. (MFEWSErrorDomain error 46.)

Does anyone know of a solution or a hack (using Powershell, etc) to delete or hide that useless folder for good? I have admin access on the account if that matters. I’ve searched around a little bit but most “solutions” I found are completely irrelevant.

Regards.
