Microsoft Online Single Sign On Oddity


I’ve been working with MS Online (BPOS) for quite some months but it’s only now, with more and more customers looking into it for their environments that we’re seeing the odd little questions etc we didn’t anticipate.

This is one that came up today and, while it might be obvious to some of you, it probably won’t to others 🙂

BPOS provides users with a Single Sign On (SSO) client that logs them into the online services when they log into Windows, thus removing the need for repeated entering of credentials. If you right click the SSO icon in the System tray-it will launch you right into the app…unless it’s Outlook Web Access. When you try and run OWA, it requires you to enter your username and password each time; the reasoning behind it is a lack of pass-through authorization for increased security.

The upshot is…if you use Exchange Online but don’t have Outlook-you can’t use the Single Sign On to access your email. Maybe not the most common request but I’ve already have it once so you  never know 😛
