Neil McDonald's Dynamics 365 Blog

We were recently moved from Microsoft Business Productivity Online Standard Suite (BPOS) to the new Office 365 platform.

BPOS was built on the 2007 range of Microsoft’s server products, so the step up to SharePoint and Exchange 2010 is very welcome.

However, I needed to reconfigure our CRM email router to process emails from the new system.

I tried all sorts of weird and wonderful email server URLs and kept being greeted by ‘401 Unauthorised errors’. Using auto-discover seemed to work for a few of the mailboxes, but it was very slow and occasionally stopped working until the Email Router service was restarted.

Finally, I got it working. After accessing webmail from the 365 portal, take the URL from the address bar and adapt it for the Exchange web service URL e.g.

My Email Router configuration profiles for both outgoing and incoming mail look like this: –

Now when testing the connection on users and queues, I’m greeted with the familiar Incoming Status: Succeeded message.

Another problem I faced was user passwords being incorrect. Before you are transitioned to Office 365, Microsoft advises you to change your BPOS password, so that it is replicated in the 365 system. If users don’t do this, they won’t be able to access their email until the transition has been marked as complete. Neither administrators or Microsoft support can reset passwords until it has been completed.

Frustratingly, it took 5 days to complete our transition, so some of our users were locked out for quite some time.

Luckily, if the user can remember their old password, they can still sign in with the Microsoft Online Sign-In tool, change their password and then log into Office 365. If they can’t remember it, pray that your transition is a fast one!
