Accessing email through a mobile device

Thanks, but after calling support,  no one could assist.  Having a samsung s9+and or samsung tabs4, neither of which can I setup a email address through any of a dozen apps. None work. I have tried many times and support doesn't know any advanced setup or tips and tricks, all they do is read off a script.  They say all you do is put user name or email and password and voila. Merd. It doesn't work.  Having to login manually through your customer website and access mail defines the purpose of Having a mobile phone and or tablet for the go. Complete waist of time. Do I download the videotron app does it offer this service?!? Or just another waisted time.. I have put this off after my last reply cause there really isn't effort in trying to fix this problem.
