Manually configure Outlook 2010 for Exchange Online (BPOS)

I live in Outlook, I think most people probably do too, so having recently moved the email for my domain over to something a little more reliable – BPOS – I thought it’d be nice to have access to that inbox through my Outlook, in addition to my Microsoft email. To help with the setup of email the Sign In application can do it all for you the client’s available from the Administration Center or the download site.

This however results in you having a separate profile within Outlook so it’s not quite what I wanted.

This is what you need to do to add an Exchange Online mailbox to an existing Outlook profile in Outlook 2010 (the basic steps are universal):

Close Outlook
Open Mail32 (32-bit") from Control Panel
Click E-mail Accounts… and then New…
Select E-mail Account and click Next on the wizard
Select Manually configure server settings or additional server types and Next again
Select Microsoft Exchange or compatible service and Next again
Now fire up your browser of choice, IE nach, and log into your Outlook Web Apps.
Look in the top right and you’ll see Options, then select About and copy the name next to Mailbox server name
Go back to the mail settings dialogue and paste the name of your Exchange Online server in Server and your full Exchange Online email address in User Name
Click the More Settings… button in the lower right and select the Connection tab, tick Connect to Microsoft Exchange using HTTP and click Exchange Proxy Settings…
Next you’ll need the address of the mobile device URL for your region which you’ll enter in the first field, then click OK a couple of times to get back to the wizard
