Task List for Offering TTS Access to Exchange E-Mail
To enable users to use TTS, complete the following tasks in the order presented.
Caution Using TTS to access Exchange 2007 e-mail is supported. However, creating and installing an SSL server certificate on Exchange 2007 servers to secure TTS access to Exchange e-mail is currently not supported. When support is added, a tech note will be posted on Cisco.com.
1. Configure access to Exchange mailboxes:
a. If all of the Exchange mailboxes that users want to access are in Exchange 2007, skip to Step e.
If any of the Exchange mailboxes that users want to access are in Exchange 2000 or Exchange 2003, create an Active Directory service account that Connection uses to access Exchange data, and grant the account the necessary permissions. See the "Creating and Configuring an Active Directory Service Account (Exchange 2000 and Exchange 2003 Only)" section.
b. Create and install an SSL server certificate on each Exchange server on which you want to access e-mail messages. See the "Creating and Installing SSL Certificates (Exchange 2000 and Exchange 2003 Only)" section.
c. Optional but recommended: Configure IIS not to accept unencrypted communications from web clients including Connection. See the "Requiring Secure Communication Between Connection and Exchange (Exchange 2000 and Exchange 2003 Only)" section.
d. Configure Connection to trust the SSL certificates that you created and installed on the Exchange servers. See the "Configuring the Connection Server to Trust Exchange Certificates (Exchange 2000 and Exchange 2003 Only)" section.
e. Create Connection external services. See the "Creating Connection External Services to Specify the Exchange Servers That Users Can Access by Using TTS" section.
2. Associate users with a class of service that offers a license to access the TTS feature, and enables them to use it. See the "Text to Speech Access to Exchange E-Mail" section in the "Setting Up Features and Functionality That Are Controlled by Class of Service" chapter of the User Moves, Adds, and Changes Guide for Cisco Unity Connection, available at http://www.cisco.com/en/US/products/ps6509/prod_maintenance_guides_list.html.
3. For each user, create an external service account in Connection that specifies the Exchange server on which the mailbox for the user is stored. This enables the user to access their e-mail when they log on to Connection by phone.
4. If you have users who access their e-mail messages on a Microsoft Exchange server by using Outlook (with MAPI) or Outlook Web Access and will also use Connection to manage e-mail messages, make sure that they understand how each application handles deleted messages. See the "Potential User Concerns and Misconceptions" section in the "Operator and Support Desk Orientation" chapter of the User Workstation Setup Guide for Cisco Unity Connection, available at http://www.cisco.com/en/US/products/ps6509/prod_maintenance_guides_list.html.
Enabling IMAP Access to Exchange
Cisco Unity Connection uses the IMAP protocol to access e-mails in Exchange so the messages can be played by using TTS. By default, Exchange is not configured to allow IMAP access to messages. Do the following procedure to enable IMAP access on each Exchange server that contains e-mails that you want licensed Connection users to be able to listen to by using TTS.
Enabling IMAP Access to Exchange
Step 1 On an Exchange server that contains e-mails that you want licensed Connection users to be able to listen to by using TTS, log on to Windows by using an account that is a member of the local Administrators group.
Step 2 On the Windows Start menu, click Administrative Tools > Services.
Step 3 In the right pane, find the Microsoft Exchange IMAP4 service.
Step 4 If the value of the Status column is Started and the value of the Startup Type column is Automatic, skip to Step 9.
If the values are different, double-click Microsoft Exchange IMAP4.
Step 5 In the Microsoft Exchange IMAP4 Properties dialog box, if Startup Type is not Automatic, change it to Automatic.
Step 6 If Service Status is not Started, click Start.
Step 7 Click OK to close the Microsoft Exchange IMAP4 Properties dialog box.
Step 8 Close the Services MMC.
Step 9 Repeat Step 1 through Step 8 on each Exchange server that contains e-mails that you want licensed Connection users to be able to listen to by using TTS.
Creating and Configuring an Active Directory Service Account (Exchange 2000 and Exchange 2003 Only)
Cisco Unity Connection accesses Exchange 2000 and Exchange 2003 e-mail by using an Active Directory account that acts as a proxy for Connection. Do the following procedure to create the service account and give it the necessary permissions.
To Create and Configure a Service Account that Can Access Exchange E-Mails
Step 1 On a computer on which Active Directory Users and Computers and Exchange System Manager are installed, log on to Windows by using an account that is a member of the Domain Administrators group.
Step 2 On the Windows Start menu, click Programs > Microsoft Exchange > Active Directory Users and Computers.
Step 3 In the left pane, expand <Server name>, right-click Users, and click New > User.
Step 4 Follow the on-screen prompts to create a domain user account. Do not create a mailbox.
Step 5 On the Windows Start menu, click Programs > Microsoft Exchange > System Manager.
Step 6 In the left pane, expand Servers.
Step 7 Right-click the name of the Exchange server that contains mailboxes that will be accessed by Cisco Unity Connection, and click Properties.
Step 8 In the <Server name> Properties dialog box, click the Security tab.
Step 9 Click Add.
Step 10 Specify the service account name, depending on the Exchange version:
Exchange 2003
|
a. In the Select Users, Computers, or Groups dialog box, in the Enter the Object Names to Select field, enter the name of the service account that you created in Step 4.
b. Click Check Names.
|
Exchange 2000
|
a. In the Select Users, Computers, or Groups dialog box, in the Look In list, click the name of the domain in which you created the service account in Step 4.

The Delegate Control dialog box reappears. The account you selected appears in the Group (Recommended) or User box.
|
Step 11 Click OK to close the dialog box.
Step 12 In the <Server name> Properties dialog box, in the Group or User Names list, click the name of the service account.
Step 13 In the Permissions For <Account name> list, set the permissions:
a. For Full Control, check the Deny check box.
b. For Receive As, check the Allow check box
Step 14 Click OK to close the <Server name> Properties dialog box.
Step 15 Repeat Step 7 through Step 14 for each additional Exchange server on which you want to access e-mails.
Creating and Installing SSL Certificates (Exchange 2000 and Exchange 2003 Only)
In this section, you create and install an SSL certificate on each Exchange server that contains e-mails that you want licensed Connection users to be able to listen to by using TTS. This prevents Cisco Unity Connection from sending the credentials of the service account that you created in the "Creating and Configuring an Active Directory Service Account (Exchange 2000 and Exchange 2003 Only)" section over the network as unencrypted text. It also prevents Exchange from sending e-mail content over the network in unencrypted text.
If you use another method to create and install certificates, use the applicable documentation.
This section contains four procedures. Do them in the order listed, as applicable.
If you want to issue SSL certificates by using:
•Microsoft Certificate Services—do the following procedure on any server in the same domain as the Exchange servers that contain e-mails that you want licensed Connection users to be able to listen to by using TTS.
•Another application—see the documentation for that application for installation instructions. Then skip to the "To Create a Certificate Signing Request" procedure.
•An external certification authority—skip to the "To Create a Certificate Signing Request" procedure.
To Install the Microsoft Certificate Services Component
Step 1 Locate a Windows Server 2003 disc, which you may be prompted to use to complete the installation of the Microsoft Certificate Services component.
Step 2 Log on to Windows by using an account that is a member of the local Administrators group.
Step 3 On the Windows Start menu, click Settings > Control Panel > Add or Remove Programs.
Step 4 In the left pane of the Add or Remove Programs control panel, click Add/Remove Windows Components.
Step 5 In the Windows Components dialog box, check the Certificate Services check box. Do not change any other items.
Step 6 When the warning appears about not being able to rename the computer or to change domain membership, click Yes.
Step 7 Click Next.
Step 8 On the CA Type page, click Stand-alone Root CA, and click Next. (A stand-alone certification authority (CA) is a CA that does not require Active Directory.)
Step 9 On the CA Identifying Information page, in the Common Name for This CA field, enter a name for the certification authority.
Step 10 Accept the default value in the Distinguished Name Suffix field.
Step 11 For Validity Period, accept the default value of 5 Years.
Step 12 Click Next.
Step 13 On the Certificate Database Settings page, click Next to accept the default values.
If a message appears indicating that Internet Information Services is running on the computer and must be stopped before proceeding, click Yes to stop the services.
Step 14 If you are prompted to insert the Windows Server 2003 disc into the drive, insert either the Cisco Unity Connection disc, which contains the same required software, or a Windows Server 2003 disc.
Step 15 In the Completing the Windows Components Wizard dialog box, click Finish.
Step 16 Close the Add or Remove Programs dialog box.
Do the following procedure for each Exchange server that contains e-mails that you want licensed Connection users to be able to listen to by using TTS.
