New Outlook Layout - How do I add more columns (Size of Mail) to the inbox?

Why the hell would Microsoft remove the columns to and from and size from the freakin email columns . . thats like "day one stuff" for email . . and then . .remove any ability to add them? Do they use email still at Microsoft? This is essential?

I am gonna make two assumptions...

1. Microsoft cares more about how 'New' Outlook looks than how it functions/how useful it is;
2. They will add these features 'back' in future, at a higher subscription price!

Also complaining - I have just tried to switch, having ignored the new app for many months...first thing I tried to do was add columns. I thought it was me doing something wrong, so have wasted an hour. Amazing tis functionality doesn't exist.

UIninstalling the new app, keeping the old.

I hope you have better luck switching back from the 'New' Outlook to the Classic version (desktop app). Since I did it, 99% of my incoming emails - including from long-term, established Sender's such as Microsoft Community - are now sent to Junk!!!

[Outlook for Windows Desktop] The inability to add columns was the final straw for me; I'm going back to the old Outlook. The column I needed is the "sender email" column, which allows you to easily spot most of the phishing and spoofed emails for easy deletion (it shows the actual email address, not the sender name). Not having that available is a deal killer. Add to that the extremely limited adjustment that can be made to the ribbon, and the loss of the Quick Access toolbar, and the new offering is so bad that if they discontinue the old outlook, I'll have to look for an entirely new email client.

I came here looking for a solution and its clear there isn't one. Managing the large volume of emails I receive is criticial to my efficiency at work, losing this functionality is major problem for me.

I hope we can carry on using the old version until I retire!!
