I'm using office 365. I want to remove my email from deleted items as it's taking too much space i.e 70 GB. I tried to delete it from the clean mailbox section but since there is too many email it can not delete.
Anyone has any suggestion how can I delete the emails?
Note: This is a Microsoft saas and I don't have access to server. I have an Admin portal. Is there a way I can assign rule to delete the folder every day?
