I have a user that has 450 folders under a root folder called Active. Is there shell command to not only delete the contents of the folders, but the folders themselves?
As far as my knowlegde goes, you cannot delete a mailbox subfolder in a specific mailbox from the shell, you can however:
Give yourself FullAccess permissions on the mailbox in question:
Then add the mailbox in Outlook (Go to accounts -> choose your account -> change -> email -> add), and then delete the folder you wish to remove
