Standard TSM security requirements apply to the Tivoli Data Protection for Microsoft Exchange application client. That is, the application client must be registered to TSM and use the appropriate node name and password when connecting with the TSM server.
To access the Exchange Server APIs, the application client must be running under the Site Services Account. The Site Services Account is the account under which the Exchange services are running. The scheduler service must logon using this account. The scheduler service account information can be specified using the services applet in the Windows Control Panel. For more information about the Site Services Account, see the Microsoft Exchange Server documentation.
