Ron,
Thanks for your response.
The recovery folder is completely empty. All the folders are empty, I do not have any messages at all. However, there is storage being used probably from old emails that aren't being deleted.

This particular Outlook.com account of mine isn't performing as it is intended.
Here is where the original problem occurs and I noticed the "other" taking up space in Storage. Under the Files Tab on Outlook.com, there is an attachment view.
https://outlook.live.com/files/0/
This would show all your attachments in your email. And of course, it should be empty if you do not have any emails in your mailbox. Correct? However, I have leftover metadata that is being shown of emails and attachments that were deleted many years
ago. This concerns due to privacy issues and the fact, delete command should be delete command and delete the messages and attachments. I am wondering if this issue is taking up space in the "other" storage.

The reason I have two empty Inbox's is because I'm moving my email to another platform. One Inbox (with the problems) was converted from a Hotmail account and the other one was created straight to a Outlook.com email) I still use Microsoft for other things
but trusting Microsoft with my emails has diminished. I want to make sure I don't have any information left behind.
Also, it's the same Inbox, I snipped it at the wrong level and those folders are suppose to disappear once they are empty. I tested it on the working Outlook.com account and they disappear.
I'm wondering if Microsoft can do a full hard reset of my Outlook.com mailbox as well. I think that would solve the problem since I don't have any items in it.
Any help trying to contact a software engineer would be great as well.
