Msg 14604, Level 16, State 1 Error When Changing A Database Mail Account

When attempting to change an email account in my Database Mail, I received the following error:

Msg 14604, Level 16, State 1, Procedure sysmail_verify_account_sp, Line 14
Both account parameters (id and name) cannot be NULL

The account_id and account_name parameters are required in the sysmail_update_account_sp stored procedure.  To find these, I ran the sysmail_help_account_sp stored procedure.

EXEC msdb.dbo.sysmail_help_account_sp;

Then I added the missing parameters to the sysmail_update_account_sp stored procedure.

EXECUTE msdb.dbo.sysmail_update_account_sp 
@account_id =  < account_id > ,
@account_name = '  < name > ',
@email_address = ' < updated email address > ';

Then I reran the sysmail_help_account_sp stored procedure to verify that the e-mail address was updated.
