I have my own domain with the email setup through Zoho which is great.Really great product so far.

I am of course the Super Admin  with the email account renaldo@mysite.com but I also manage for the moment the 

info@mysite.com and the support@mysite.com accounts.

On my iPhone I have it setup that I can move between theses three accounts effortlessly by taping the top of the screen "the user" and changing to view a different account.It works very well.

On my pc I want to know if I can set it up in a similar way without using IMAP or POP.

Is there somehow I can do it or if you are unsure what I mean I am happy to add some screenshots or anything to help explain more.

If you do take the time to reply.Thank you for your effort.
