How to Add an IMAP4 or POP3 Virtual Server as a Resource to an Exchange Virtual Server

 

For improved security, by default, the Windows IMAP4 and POP3 protocol services are no longer enabled on servers that are running Windows Server 2003. Similarly, by default, the IMAP4 and POP3 protocol resources are no longer created upon creation of an Exchange 2003 virtual server. This procedure outlines how to add an IMAP4 or POP3 virtual server as a resource to an Exchange Virtual Server.

Before You Begin

If you want to enable either of those protocols, you must do the following:

• Enable the Windows IMAP4 or POP3 service on those cluster nodes that will be running the Exchange Virtual Server with the IMAP4 or POP3 resource. To make sure that the service works correctly with clustering, you must also configure the service to start manually.

• Manually add the respective IMAP4 or POP3 virtual server as a resource to each Exchange Virtual Server on which you want to enable the selected protocol, and then bring the resource online. For detailed steps, see the procedure below.

Before you start managing your Exchange cluster, you may want to review what constitutes an Exchange Virtual Server and its associated Exchange resources. You may also want to become more familiar with Cluster Administrator—the primary tool used to configure and manage clusters.

Note

Before performing the cluster administration tasks outlined in this chapter, you must be familiar with the clustering concepts described in "Checklist: Preparation for installing a cluster" in the Microsoft Windows Server™ 2003 Enterprise Edition Online Help and in the Windows Server 2003 Technical Reference.

Also, make sure that you are familiar with "Using Server Clustering" in Planning an Exchange Server 2003 Messaging System and with "Deploying Exchange 2003 in a Cluster" in the Exchange Server 2003 Deployment Guide.

Procedure

To add an IMAP4 or POP3 virtual server as a resource to an Exchange Virtual Server

1. In Cluster Administrator, right-click the Exchange Virtual Server to which you want to enable IMAP4 or POP3, point to New, and then click Resource.

2. In the New Resource dialog box, do the following:

   1. In Name, type either one of the following names:

   • If you are adding the IMAP4 resource, type Exchange IMAP4 Virtual Server - (<EVSName>), where EVSName is the name of the selected Exchange Virtual Server.

   • If you are adding the POP3 resource, type Exchange POP3 Virtual Server - (<EVSName>), where EVSName is the name of the selected Exchange Virtual Server.

   1. In the Resource Type drop-down list, click one of the following options:

   • If you are adding the IMAP4 resource, click Microsoft Exchange IMAP4 Server Instance.

   • If you are adding the POP3 resource, click Microsoft Exchange POP3 Server Instance.

   1. Verify that the Group drop-down list contains the name of the selected Exchange Virtual Server, and then click Next.

3. In the Possible Owners dialog box (see the following figure ), verify that all nodes appear in the Possible owners list, and then click Next.

4. In the Dependencies dialog box, under Available Resources, double-click the <System Attendant Resource Name> to add the System Attendant to the Resource dependencies list, and then click Next.

5. In the Virtual Server Instance dialog box, in the Server Instance list, select the IMAP4 or POP3 virtual server for the resource, and then click Finish.

   1. In Cluster Administrator, right-click the IMAP4 or POP3 resource, and then click Bring Online.
