If you need to change the Vault Service account, this section describes how to proceed.
Before you change the account, ensure that the following apply:
The new Vault Service account is part of the Administrators group, with permission Full Control (All), on each Enterprise Vault computer in the Enterprise Vault Site.
If Exchange Server archiving is implemented, the new account has full permissions on the Microsoft Exchange Server.
The Microsoft Message Queue security has been set up to grant the Administrators group access to the Enterprise Vault queues.
The new account has database creator access on the SQL server.
For instructions on how to set permissions for the Vault Service account, see Enterprise Vault prerequisite software and settings in the Installing and Configuring manual.
To change the Vault Service account
Start the Administration Console as the existing Vault Service account.
In the Administration Console, open Directory Properties and click the Service Account tab.
Change the Vault Service account details to reference the new account.
Restart all Enterprise Vault services on all Enterprise Vault servers in the Enterprise Vault Site.
