(mobile and android version of outlook) the second problem is that the select all button is not designed to fit the need for speedy email sorting and configuration. It brings a serious problem to sort emails for the languid email checkers with thousands of emails piled up.

The problem still persists to trouble me everyday.

It is very troublesome log in to outlook everytime manually, does it really hurt to add an little box to saved login info for all outlook versions? 

In my opinion, there are lots of features ought to be added to optimise the program. 

I am all ears for your reply. 

thank you for helping.
