Installing Exchange Server 2010 into an existing Exchange Server 2007 environment (part 3) - Configure Exchange Web Services

2.4 Configure Exchange Web Services

Exchange Server 2010 uses the Client Access Server to offer the Offline Address Book and Free/Busy information using the HTTP protocol, and these can therefore be used by Outlook 2007 and Outlook 2010. To configure the Exchange services, open an Exchange Management Shell and enter the following commands:

In the coexistence scenario, the Offline Address Book generation server is still the Exchange Server 2007 Mailbox Server. We want to move this to the Exchange Server 2010 Mailbox Server, so we follow these steps:

  1. Log on to an Exchange Server 2010 server and open the Exchange Management Console.

  2. Expand the Microsoft Exchange On-Premises (SERVERNAME).

  3. Expand the Organization Configuration container and select the Mailbox option - click the Offline Address Book tab.

  4. Right click the "Default Offline Address Book" and select Move.

  5. Use the Browse button to select the new Exchange Server 2010 Mailbox Server and click Move.

It is also possible to move the generation server to Exchange Server 2010 using the Exchange Server 2010 Management Shell. On an Exchange Server 2010 server, open the Exchange Management Shell and enter the following command:

If your Exchange Server 2007 environment has Public Folders, it is likely that you will want these on your Exchange Server 2010 Mailbox Server as well. The Public Folder database is, in this case, automatically created, but you have to manually configure replication, which is a bit of a hassle.

  1. Log on to an Exchange Server 2007 Mailbox Server and open the Exchange Management Console.

  2. In the Exchange Management Console, double-click the Toolbox. Double-click the Public Folder Management Console in the results pane.

  3. Select the Offline Address Book and, in the results pane, right-click the "/o=<<organization>>/cn=addrlists/cn=oabs/cn=Default Offline Address Book" and then select the Replication tab. Use the Add button to add the Exchange Server 2010 Public Folder Database, and then click OK to close the properties window.

Figure 5. Add the Exchange Server 2010 Public Folder database to the replication list.

Repeat these steps for:

  • EX:/o=<<organization>>/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)

  • OAB Version 2

  • OAB Version 3a

  • OAB Version 4

  • EX:/o=<<yourorg>>/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)

  • Schedule+ Free Busy: EX:/o=<<yourorg>>/ou= Exchange Administrative Group (FYDIBOHF23SPDLT).

3 SMTP Infrastructure

The Exchange Server 2007 Edge Transport Server needs to be transitioned to Exchange Server 2010 as well. Before doing so, you need to make sure the Active Directory has been transitioned first:

  1. Install Exchange Server 2007 SP 2 on all Client Access Servers in the entire Exchange organization.

  2. Install the Exchange Server 2010 Hub Transport Server (after you've installed the Exchange Server 2010 Client Access Server!) and subscribe the existing Exchange Server 2007 Edge Transport Server to this new Hub Transport Server. This can coexist for some time if needed.

  3. Install the Exchange Server 2010 Edge Transport Server in the DMZ.

  4. Remove the subscription from the Exchange Server 2007 Edge Transport Server, and subscribe the new Exchange Server 2010 Edge Transport Server to the Exchange Server 2010 Hub Transport Server.

It's actually rather simple, although you should bear in mind that this is one of the rare cases when the relationship between Exchange Servers 2007 and 2010 is asymmetric! Specifically, an Exchange Server 2010 Edge Transport Server cannot be subscribed to an Exchange Server 2007 Hub Transport Server.

4 Moving mailboxes to Exchange Server 2010

Mailboxes should be moved from Exchange Server 2007 to Exchange Server 2010 using the 2010 version of the Exchange Management Console, or the Exchange Management Shell. Even more interesting, the new onlinemove mailbox functionality (now called MoveRequest) can be used, which results in a minimal downtime for the users. Even when they have a multi-Gigabyte mailbox!

During an online move-mailbox, a new mailbox is created on the Exchange Server 2010 Mailbox Server and the contents are synchronized between the old (on Exchange Server 2007) and the new mailboxes. The user is still working with the old mailbox and new messages still arrive at the old mailbox. When both mailboxes are in sync the old mailbox is closed, Active Directory is updated with information regarding the new mailbox location and the new mailbox on Exchange Server 2010 is fully up and running.

Lastly, note that the online move-mailbox functionality only works between Exchange Server 2010 servers, and when moving from Exchange Server 2007 to Exchange Server 2010. When moving from Exchange Server 2010 to Exchange Server 2007, the move is offline. It also doesn't work with Exchange Server 2003, which is a shame.

Either way, congratulations! You should now have Exchange Server 2010 running in Coexistence with either your Exchange Server 2003 or 2007 environment!
