Here are a few tips for making sure that you avoid some common problems:

• It is very important to set up the Vault Service account correctly and to ensure that the Enterprise Vault services run under this account.

• The Vault Service account must have the Microsoft Exchange Server permission Service Account Admin at the Site and Configuration level. See the Installing and Configuring manual for detailed information on setting up the Vault Service account.

• When you change the Vault Service account password using Windows, you must update the password in the Vault Directory Database using the Administration Console. The password is encrypted in the Vault Directory Database. See the online help for the Administration Console for more information.
