On each computer that you want to install the BlackBerry® Enterprise Server or BlackBerry Administration Service on, you must configure the Microsoft® Exchange permissions of the Windows® account that you want to use to complete the installation process.

Without the correct permissions, the BlackBerry Enterprise Server cannot run after you complete the installation process.

1. Using Microsoft Exchange 2003 System Manager, configure the Exchange View Only Administrator permission with the minimum access level of Administrative Groups.
2. At the server level, configure the following permissions:
   • Send As
   • Receive As
   • Administer Information Store
3. To permit the BlackBerry Enterprise Server to check if users have permissions to access a public folder, assign the Owner permission on all public folders to the account.

After you finish: Verify that the users have Read and Visible permissions to public folders.
