Old Outlook allowed tagging only visible Emails in current window, which was very useful for deleting batches of recent Emails... it appears that tagging multiple Emails at the header line in new Outlook will select ALL messages in the folder, which is clearly not desirable when wanting to delete selectively. Also, scrolling thru history is painful in the new Outlook ==> very difficult to browse and find a specific Email from months ago... requires pages and pages of scrolling (i.e. messages no longer one to a line). Also, I did not readily see a way to jump to a specific date.
