1. The 1st is go to Setting and tap Account
4. Add details of your account, email id and password then tap Manual Setup to input your email server (ie mail.company.com), port number (ie 110), and security type (ie None). If u receive a lot of emails, I would recommend you to tick (enable) the option Delete Email from Server when I Delete from Inbox
All the best for guys. Love your job <3<3
