Re; Outlook Mail (Preview)

I am very annoyed and unhappy with the above, because of the length of time it takes to sign into my email account.
Also the length of time it takes to open an email, or delete any unwanted mail.

Why is this, as there was nothing wrong with the Outlook.com service!!!

If this outlook preview can't be speeded up, kindly revert back to the original
Outlook.com

Unfortunately we don't work for MS so dropping this here won't have any impact
