If auto-discovery in your Office 365 account is configured properly, setting Microsoft Outlook is very simple – only information you need to is email address and password.

However, if auto-discovery is not yet configured or is not working properly, here is how to configure Outlook 2010 manually

1. Login into your Office 365 online account.
• In top right corner click on a  Help circle (question mark) >  About find line Host address: and save it for later use.
  i.e. https://db4prd5171.outlook.com/owa
2. Now add new account in your MS Outlook 2010:
• Control Panel > Mail > Email Accounts > New
• Select E-mail Account > Manually configure server settings… > Microsoft Exchange…
• Server name: the domain part of your host address with mailbox added in the middle
  i.e. db4prd5171.mailbox.outlook.com
• User Name: your full email address.
  i.e. john@mydomain.com
• Click More Settings… > Connection select Connect to Microsoft Exchange using HTTP and click Exchange Proxy Settings…
• https:// add domain part of your host address.
  i.e. db4prd5171.outlook.com
• Tick all checkboxes
• In Only connect to proxy servers that have this principal name in their certificate enter msstd:outlook.com
• In Use this authentication when connecting to my proxy server for Exchange select Basic Authentication
3. Save all changes, provide password when prompted and you should be good.
