If you are a service account manager, you can delete any service account, as long as it is not in Pending status. Complete the following steps to delete an account:
On the Home page, under Administration, click Manage Service Accounts.
Use the Filter Options to view the service account, as instructed in Searching for Service Accounts.
Select the account.
Click Delete Account.
Confirm that you wish to delete the account by clicking OK, or cancel the request by clicking Cancel.
If your request was successful, a message appears in green at the top of the page. The system verifies that the account is a service account and sends you an e-mail indicating that the account has been deleted. To verify that the account is gone from the list, click Search Service Accounts again.
