In Windows 10 and Windows 8, Microsoft has standardized a lot of things. Same settings which multiple apps use are now organized at one place or under one Setting. So this tutorial is specifically for people who are finding it difficult to add more email accounts in their Mail app. I myself faced this problem so I perfectly know how irritating this can be. Especially for those of you who are used to the desktop based Outlook software for managing your email this can be a traumatizing experience. For instance in app based interface you cannot drag and drop your emails to move them to a different folder. You have to right click first, select multiple mails and then use the Move option to move emails to different folders.
