Connecting Outlook 2013 Release Preview to O365 Manually…

in Office 365 - Exchange Mail, Outlook 2013

I have just migrated all of my home based e-mail to Office 365 (away from IMAP with my hosting provider). One thing that I noticed is that whilst my iPad and iPhone (using Active Sync) and Outlook 2011 (on my Mac Book) all connected perfectly using Autodiscover (as I had set this up for my domain) – I could not get Outlook 2013 Release Preview to connect and configure automatically on my Windows 8 PC.

Now is is entirely possible that this is down to some weird cock-up that I have made with the DNS configuration (although this would not explain the other Autodiscover aware clients working correctly) – but I found that the only solution was to manually configure the connection to the servers in the Microsoft Cloud.

Before I get going  – there is a KB article on the subject (for versions of Outlook from 2003 upwards) which can be found here: which did get me into a position where Outlook 2013 would connect – but it is quite long – therefore I have provided a summary guide below:

Get your O365 Host information

In order to configure Outlook 2013 manually for Office 365, you will need to get some information first. You will need to logon to OWA via your portal account (using and from the “Outlook” tab click on the Help icon and selection “About” – see below:


When you have clicked on the “About” menu option you will be presented with a number of session settings relevant to your O365 account – you are interested in the “Host Address” value – see the highlighted section below:


Copy the “Host Address” value (which will be in the format of <ServerName> a text editor like Windows Notepad and make the following modifications:

  • Remote the https:// and /OWA elements
  • Make another copy of the string that you are left with (which should be <ServerName> on another line
  • Change one of the values to <ServerName>

See below for an example of the above:


Manually Configuring Outlook 2013 – Release Preview

Open the Mail Control Panel applet and click on the “Show Profiles” button


From the “Mail” dialog box that appears click on the “Add” button – see below


Give your profile a descriptive name and then click on the “OK” button – see below


From the “Add Account” dialog – select the “Manual setup or additional server types” radio button and then click next – see below


On the next screen ensure that the “Microsoft Exchange Server or compatible service” radio button is selected and then click “Next” – see below


On the next screen, in the “Server Settings” area – for the “Server” value – copy and paste the entry in your Notepad session which looks like <ServerName> For the User Name value – provide your Office 365 logon account which should be <some alias> You can customise the "Offline Settings” to suite you own requirements.

When you are done – click on the “More Settings” button – see below


From the dialog box that appears click on the “Connection” tab – tick the “Connect to Microsoft Exchange using HTTP” and then click on the “Exchange Proxy Settings” button – see below

In the “Connection Settings” area – populate the proxy URL with the <ServerName> value from Notepad. Ensure that the “Connect using SSL only” tick box is ticked and then tick the “Only connect to proxy servers that have this principle name in their certificate”.

You will need to then provide the following principle name:

Tick the “On fast networks, connect using HTTP first, then connect using TCP/IP” and then change the “Proxy authentication settings” to “Basic Authentication” – see below


When you are done – click the “OK” button until you are returned to the parent “Add account” dialog box.

Click on the “Check Name” button and you will be prompted for a Username and Password – you should enter in your O365 account ID and password (this should be in UPN format of <alias>@<>) and then click on the “Next” button.

You should now be able to connect to your Office 365 account from Outlook 2013.
