Troubleshooting Credential Change Failures Each credential in the Credential Manager has three parts—an account name, a password and an optional description—and you can change any of them. While most changes should be processed smoothly, occasionally issues in the network environment may prevent changes from being applies. When a change fails, you need to determine the reason, and then manually make the changes. If a report schedule fails after changing a credential, it could mean that: • Your credentials do not have access to the delivery share. Ensure the credentials are valid, and that they have write access to the share. • Your credentials are not valid for your SMTP server. You can test the credentials in the SMTP configuration dialog box. For more information, see Delivering Scheduled Reports by Email.
