The Microsoft Lync Server 2010 Multitenant Pack for Partner Hosting is an extension of Microsoft Lync Server 2010 software that is designed to allow service providers and system integrators to customize a Lync Server 2010 deployment and offer it as a service to their customers. This guide describes how to deploy and configure a basic architecture.

I just read the document and the key takeaways are:

• Edge Servers only act as the first point of contact from requests coming from federated partners in a hosted deployment
• In a Lync Server Multitenant Hosting Pack deployment, incoming requests from tenant users go straight to Directors, bypassing Edge Servers. The Directors authenticate tenant users’ requests and redirect them to the appropriate Front End pool
• You must configure the DNS records for the initial SIP domain. Configure the SRV record to point to the Director pool, not the Edge Server pool.
• The Directors require public IP addresses that do not use NAT.
• You must run the Lync Server Update tool on each server in your deployment after you complete the Setup or Remove Lync Server Components page in the Lync Server Deployment Wizard
• Additional task must be performed before and after you have done a default Lync deployment
• The Lync Server platform must be configured to treat all clients as external to ensure that their private and public IP addresses are provided to Exchange UM when calls are transferred from the Front End Server to the Exchange UM server.
• To prevent a tenant from communicating with another domain you must add that domain to the tenant’s Block list
• You need to add new SIP domains to the certificate
• You can’t use Response group, Team call,delegation, Private line, Call park, Outgoing DID manipulation,
• No Public IM connectivity with Windows Live, AOL, Yahoo, and XMPP

This was what I could see was different from a normal Lync Deployment, and you need to run some scripts to get it up running.

The features that integrate with other components and applications include the following:

· Presence   A collection of attributes that provides an indication of a person's status, activity, location, willingness to communicate, and contact information.
