I agree with Jon's comments, but I would like to emphasize the "this change is horrible" part.
It may be more user friendly on phones (easier to read and click on the buttons), but what I was able to scan in a few seconds before, now feels like reading a book. Painful and slow to read - especially when 20 or 30 of the emails are all the same subject.... This is WAY to time consuming.
Most of my users are asking to move away from Barracuda - they now prefer to login to the web interface to see the emails in table format.
Please read the table format back....or give us the option.
