Sort search groups by amount of items?

I have added my Hotmail account to Outlook 365 (desktop), which is basically Exchange.

In my Inbox, I've clicked on the From column to sort the e-mails into Groups.

I've then collapsed the Groups.

Is it possible to sort the Groups by most items first, rather than alphabetical?

I basically want to see who I've received the most e-mails from.
