About the Exchange Service Account

The user account under which the Exchange Connector runs is known as the Exchange service account. The Exchange service account must have read-write privileges to the Microsoft Exchange mailboxes of all synchronization-enabled users. Therefore, the Exchange service account must be a domain account, not a local account.

Provided there are trust relationships between all the Active Directory domains in which your Exchange Servers are deployed, you require only one Exchange service account for your whole Microsoft Exchange infrastructure, regardless of how many Exchange Servers you have. Exchange Servers are not listed in the Siebel database. Instead, the Exchange Connector queries the Active Directory Global Catalog at runtime to determine which Exchange Server handles the mailbox for a given user (SMTP email address).

NOTE:  If you are using the DCOM Exchange Connector, the Exchange service account can be administered entirely by your Windows administrators. Siebel administrators do not have to know the login credentials for the Exchange service account. However, if you are using the Web service Exchange Connector, the Siebel Server service must run with the credentials of the Exchange service account user.

To manage the process of giving the Exchange service account read and write access to SSSE user mailboxes, you can use a script that gathers information about the applicable users from the Siebel User Map view. For more information about the script, see Configuring User Mailbox Access for the Exchange Service Account. Alternately, you can place all Microsoft Exchange mailboxes for SSSE users on one or more designated Exchange Servers, and give the connector read and write access at the server level, but this approach is not recommended if Exchange user mailboxes are frequently moved between Exchange Servers.

NOTE:  Each user to be synchronized must have an active Exchange mailbox and must not have the Active Directory attribute, Hide from Exchange Address Lists, set to TRUE. The Exchange service account must also have an active Microsoft Exchange mailbox.
