Additional preinstallation tasks for Operations Manager

In the Active Directory domain, create a Windows user account named, say, "MonitoringUser", for Operations Manager to use when accessing the Enterprise Vault databases. This monitoring user account does not require an Exchange mailbox, and it need not be a member of the Windows Administrators group.

When you create the monitoring user account, note the following:

Select the Password Never Expires option.
Leave the remaining check boxes clear (User Must Change Password At Logon, User Cannot Change Password, and Account Is Disabled).
