Can I force delete a specific email folder with Powershell?

Greetings to dear Tech Community users,

I am an administrator of 11 users with an Office365 E3 license. Mail that I deleted in OWA is coming back. There is no "retention policy" available. I want to completely delete the contents of the two folders.

Can I force delete a specific email folder with Powershell? These folders are also available for other users. I need to delete them too.

NOTE: All my users only use Outlook Web Access (OWA). Also, the e-mail folder names I want to delete are "Bank Account" and "Deleted Items".

Thank you in advance for your help.
