Hello,
Verify the following settings which should resolve your issue :
1.Before you click Test Access, make sure that the user has logged on to the mailbox so that the mailbox is activated.
2.Make sure that you can receive e-mail messages in the mailbox.
3.In the Location section of the E-mail Router Configuration Profile dialog box, verify that the correct URL of the Exchange Server is entered. For example:
â—¦http://myexchangeserver
â—¦www.myexchangeserver.local
Important: Do not enter any additional characters at the end of the URL string, such as /OWA or /Exchange or even a / character. If you are using SSL, be sure to use https in the URL instead of http.
4.Verify the settings in the Access Credentials section of the E-mail Router Configuration Manager incoming profile dialog box:â—¦Make sure that the specified user has full access rights to the mailboxes that this incoming profile will serve. To test this, log on to the computer that is running the E-mail Router by using the specified access credentials, or in Internet Explorer, try to access the Outlook Web Access URL of the user that you are testing (for example, http://exchangeserver/Exchange/crmuser).
For instructions about how to grant this access in Exchange Server 2003, see TechNet article How to Give a User Full Access to Another User's Mailbox.
For instructions about granting this access in Exchange Server 2007, see TechNet article Add-MailboxPermission.
â—¦If you have selected the User Specified option in the Access Credentials drop-down list, make sure that the users whose mailboxes this profile will serve have set their user name and password in the Set Personal Options dialog box (available in the Workplace section of the Web application). This enables the E-mail Router to access mailboxes by using each user's access credentials.
Note: The User Specified option is intended for use in scenarios where the E-mail Router is configured to monitor user mailboxes, instead of a forward mailbox. This option is available only in the On-Premise version of the product.
