Can access email through OWA but having trouble setting it up in Outlook 2013.

Hello,

I am trying to set up my email account in Outlook 2013 which I have installed via Office 365 on a laptop with Windows 8.1.

I can access the email using Outlook Web Access but when I try to set it up in Outlook 2013 a window keeps popping up asking for my username and password. If I continue Outlook eventually sets the account up as a pop type account but I would like an exchange type account so I can access my calendars and appointments, etc.

I have a video on YouTube demonstrating the problem but it is not allowing me to post a link to it.

Do you have any suggestions I could try to get this account set up correctly (as an exchange account) in Outlook 2013?

Thanks

Randy
