I have added an email account to my Windows phone which connects to my institutional email inbox. It is not Gmail, YMail, or Outlook so there are no apps already so I can add the app to Start for convenient access. Is there a way other than linking the mail account to Outlook inbox to add the inbox for this new email account to the Start Menu?
Email inboxes show up in the app list. So you can simply find your inbox there, long-press (press and hold) on it until a context menu pops up, then select "pin to start".
