Hi Welcome to JustAnswer
Which error message you getting when you are trying to add email id ?
Make sure that you know your email settings. Then follow these steps:
If Mail can't find your email settings, you need to enter them manually. After you enter your email address and password, tap Next, then follow these steps:
I also tried to search for setting for 365.com but google does not have any thing on it. You will have to check for its settings from its email provider. It seems to be specific to china only. Please try and contact your email service provider to get incoming and out going server details.
For you its a language barrier but for me its access restriction. I am not able to see any post of 365.com .Seems like google does not recognizes it. Can you visit some of the site from there and try using google translator ?
