Building Hosted Exchange – Part IV

In my earlier blog posts Building Hosted Exchange Part I (overview), Building Hosted Exchange Part II (Active Directory) and Building Hosted Exchange Part III (Exchange and ABP’s) we’ve created a simple Exchange 2010 organization that’s capable of hosting multiple organizations, separated from each other and each having their own Address Books. But as outlined in the Microsoft guidance document there’s more involved, especially when it comes to global settings that are identical for all users (in all organizations) or global settings that can reveal unwanted information.

Global Exchange configuration

When building a hosted Exchange 2010 SP2 environment a number of Exchange configuration settings have to be taken into account.

There are certain global settings that are valid for the entire organization and are therefore set on an organization level and not on a tenant level. Example of these configurations (this is not a complete list!) are Exchange ActiveSync settings, Exchange Web Services, OWA policies, Throttling policies, anti-virus and anti-spam checking, postmaster settings and the autodiscover settings.

Autodiscover in Exchange part III

Autodiscover is a standard feature in Exchange Server 2007 and higher that’s being used by Outlook 2007 and higher. Looking at the number of questions I get regarding autodiscover I’ve written a number of blogposts that will look into Autodiscover in depth:

In Part I I’ve explained how domain joined clients work with autodiscover information that’s stored in Active Directory. In Part II I’ve explained how the same (domain joined) client behaves on an external network like the Internet.

Both posts work with the self-signed certificate, but it’s much better (and recommended!) to use a 3rd party certificate or a certificate of an internal PKI environment. Continue reading Autodiscover in Exchange part III

Exchange 2010 and Autodiscover Part II

Autodiscover is a standard feature in Exchange Server 2007 and higher that’s being used by Outlook 2007 and higher. Looking at the number of questions I get regarding autodiscover I’ve written a number of blogposts that will look into Autodiscover in depth:

In Part I I’ve explained how domain joined clients work with autodiscover information that’s stored in Active Directory. This is easy for domain joined clients that have access to the internal network, but it’s a bit different for domain clients that have no access (i.e. working from home or a hotel) and for non-domain joined clients. The latter don’t have access to Active Directory and there cannot query AD for the Service Connection Point of course.

In this post I’ll discuss the same client as in Part I, but this time when there’s no access to the internal network (and thus no access to Active Directory). Continue reading Exchange 2010 and Autodiscover Part II

Autodiscover in Exchange

Autodiscover is a feature in Exchange Server 2010 and higher which is being used by Outlook 2007 or higher. Due to the number of question I get on Autodiscover I’ve created a number of blog posts that explain the Autodiscover functionality:

Introduction

Autodiscover is a very useful feature in Exchange 2007 and Exchange 2010 that makes it possible to automatically create Outlook 2007 and Outlook 2010 profiles.

Building Hosted Exchange – Part III

In my earlier blog posts Building Hosted Exchange Part I (overview) and Building Hosted Exchange Part II (Active Directory) I explained the basics and how to configure Active Directory for a multi-tenant environment. In this posting we’re going to continue with the Exchange part of the multi-tenant environment.

Exchange 2010 SP2

In the previous post I used a simple Powershell script to create the Organization Units in Active Directory for three different companies that will be hosting in our sample environment. Besides the creation of the OU’s the script also sets the appropriate permission on the OU’s. The structure looks like this: Continue reading Building Hosted Exchange – Part III
