Almost two years ago I wrote a couple of blog posts regarding Hosted Exchange 2010 SP2 (or later):

When building Hosted Exchange 2013 things are not very different. You have to prepare Active Directory for hosting purposes and set the permissions in Active Directory on OU level. When it comes to Exchange 2013 itself, address list segregation is still achieved by using Address Book Policies. One thing that is fundamentally different is SMTP routing in a hosted Exchange. In Exchange 2010 3rd party Routing Agents were used, but in Exchange 2013 there’s an Address Book Policy Routing agent that respects the Address Book Policies that are provisioned for every tenant.

In my previous blog post I tried to explain why Microsoft is following the partner model for hosted environment.

Exchange Schema Versies

Leave a comment

Every Exchange version comes with its own Active Directory Schema updates, even Cumulative Updates come with Schema updates these days. To determin the version of the Schema when it comes to Exchange you can verify the rangeUpper property of the ms-Exch-Schema-Version-Pt object in the Schema Partition as shown in the following figure (for Exchange 2013 CU8).

You can also use the following PowerShell commands to retrieve the Schema version:

$root = [ADSI]"LDAP://RootDSE"
$m = [ADSI]("LDAP://" + "CN=ms-Exch-Schema-Version-Pt," + $root.schemaNamingContext)
$m.rangeUpper

The following table lists all (or most) Schema versions of Exchange Server:
