Migration Manager for Exchange 8.15 - Target Exchange 2007 Environment Preparation

Setting up Target Exchange Organization for Internet Mail Flow between Target and Source Exchange Organizations

You need to establish Internet mail flow between the target and the source Exchange organizations. For that, one of the following methods can be used:

• Establishing Internet mail flow directly through a Hub Transport server.
• Establishing Internet mail flow through a subscribed Edge Transport server.

Establishing Internet Mail Flow Directly Through a Hub Transport Server

If you choose this option, you need to create an Internet Send connector and Receive connector on an Exchange 2007 Hub Transport server that can be directly reached through the Internet.

To establish mail flow to and from the Internet through a Hub Transport server, follow these steps:

1. Create a Send connector (to send email from source (target) Exchange 2007 organization to the Internet) on the Hub Transport server.
2. Modify the default Receive connector for the source (target) domain to accept anonymous e-mail from the Internet
3. Add the e-mail domain used for redirection to the list of accepted domains on the Hub Transport server.

Each step is explained in further detail in the related subtopics.

Creating Send Connector

To create a Send connector, you can use either Exchange Management Console or Exchange Management Shell.

To create a Send connector using Exchange Management Console

1. Open the Exchange Management Console. Select Organization Configuration | Hub Transport.
2. In the action pane, click New Send Сonnector. The New SMTP Send Сonnector wizard runs.
3. When prompted, in the Name field, type a unique name for the connector, for example, "QMM Send Connector." From the Select the intended use for this Send connector drop-down list, select Custom, and then click Next.
4. On the Address space page, click Add. In the dialog box displayed, specify the address space you want to use for mail redirection from source to target (target to source) organization (for example, *.target.local or *.source.local), select the Include all subdomains option, click OK and then click Next.
5. On the Network settings page, select Use Domain Name System (DNS) "MX" records to route mail automatically. Select the Use the External DNS Lookup settings on the transport server option.
6. Next, on the Source Server page, click Add. In the dialog box displayed, select one or more Hub Transport servers in your organization, click OK and then click Next.
7. Finally, on the New Connector page, click New, and then on the Completion page, click Finish.

To create a Send connector using Exchange Management Shell

Run the following command for the source Exchange organization:

new-SendConnector -Name 'QMM Send Connector' -Usage 'Custom' -AddressSpaces 'SMTP:*.target.local;1' -IsScopedConnector $false -DNSRoutingEnabled $true -UseExternalDNSServersEnabled $true -SourceTransportServers 'ServerName'

where:

• *.target.local is the address space you want to use for mail redirection from source to target organization.
• ServerName is the Hub Transport server name.

Run the following command for the target Exchange organization:

new-SendConnector -Name 'QMM Send Connector' -Usage 'Custom' -AddressSpaces 'SMTP:*.source.local;1' -IsScopedConnector $false -DNSRoutingEnabled $true -UseExternalDNSServersEnabled $true -SourceTransportServers 'ServerName'

where:

• *.source.local is the address space you want to use for mail redirection from target to source organization.
• ServerName is the Hub Transport server name.

Modifying Default Receive Connector

To modify the default Receive connector for the source or target Exchange 2007/2010 organization to receive mail from the Internet, you can use either Exchange Management Console or Exchange Management Shell.

To modify the default Receive connector using Exchange Management Console

1. Run Exchange Management Console. Select the Server Configuration | Hub Transport node.
2. In the Hub Transport pane select the appropriate Hub Transport server.
3. On the Receive Connectors tab, select the Default <Server Name> connector. In the Actions pane, click Properties for this connector.
4. In Default <Server Name> Properties dialog box, open the Permission Groups tab.
5. Select Anonymous Users to add anonymous permissions.
6. Click OK to apply the settings.

To modify the default Receive connector using Exchange Management Shell

Run the following command:

Set-ReceiveConnector -PermissionGroups 'AnonymousUsers, ExchangeUsers, ExchangeServers, ExchangeLegacyServers' -Identity 'ServerName\Default ServerName'

Where ServerName is the Hub Transport server name.
