Recently Microsoft announced they will offer to deploy BPOS to customers with 2400 seats and up. This offering will support their FY11 objectives for BPOS deployments:

• Increase velocity of customers' move to BPOS while simultaneously reduce time and effort required to deploy, especially for our larger customers, so that customers can realize value faster from BPOS
• Make deployment cost more predictable and ensure that customers have a deployment plan at time of sale of BPOS, and establish time-to-deploy standards to manage customer expectations

In a post on the msonline blog Microsoft says the following about this:

We will also continue to offer BPOS-S deployment, now called Microsoft Premier Deployment (MPD), to large BPOS-S customers in FY11 since we want to provide additional deployment capacity and expertise needed in the market to meet the accelerating demand for deployment from our expanding customer base.

The actual activities performed by Microsoft are focused on getting customers in the cloud. Activities like creating SharePoint Online sites etc. are not taken care off:

Microsoft Premier Deployment (MPD) will include preparation for BPOS directory, messaging coexistence, messaging data migration (mail, calendar, contacts), and onsite and offsite deployment consultant (as appropriate). MPD will not include moving data and apps to SharePoint Online, custom development, AD federation/synch with MS Online, client software deployment, change management, etc.,.

What's really missing in my opinion is that Microsoft does not setup AD federation etc.

Microsoft Partners will play a significant role in the deployment of BPOS environments. To further clearify this Microsoft announced that partners will be given a head up in the actual activities and costs associated with deployment:

We have also streamlined the process of selling MPD. When Microsoft submits a deployment proposal, the account team will submit a deployment Statement of Work (SOW) using a standard MPD template and price it using a publicly available rate card. Microsoft will publish standard rates on per seat basis to provide customers clarity and predictability of cost.
