Exchange 2010 OWA Access Not working

I'm trying to get familiar with Exchange 2010.  After installation I was trying to get access to OWA but keep getting an error "The item you tried to access no longer exists"  I looked for some info but could not find anything specific to this issue.  Any ideas.
Thanks for your time.

I find out my problem. I guess is different now with Exchange 2010.
I was under the impression that by creating a user account with the New Mail User option, I was also creating the mailbox. I was not.   This option does not create the mailbox.  Then reading  more about this Exchange box, I find out that we have couple of options to do that, including the shell.  So I went back and selected the New Mailbox option and that not only created the network user account but also the mailbox.

I have included the intructions below from an Exchange 2010 Book.
I guess the pictures I posted earlier will be a good indication when users dont have a mailbox, Duh!
Thank you All

Creating User Mailboxes
The creation of a new user mailbox, either for an existing user or in conjunction with the
creation of a new user, is an example of a task that can be accomplished from any of the
three administrative tools. For this example, we show how to perform the task using all
three tools.
Exchange Server 2010 allows for the creation of four different types of mailboxes:
1. User Mailbox—Owned by a user and used to send and receive messages. This
mailbox cannot be used for resource scheduling.
2. Room Mailbox—Intended for room scheduling and not owned by a user. A user
account is created with the mailbox, but the account is disabled.
3. Equipment Mailbox—Intended for equipment scheduling. Like the room mailbox,
this is not owned by an active user. The associated user account that is created will
automatically be disabled.
4. Linked Mailbox—Accessed by a user in a separate, trusted forest.

However, only a user mailbox can be created with the ECP. For our following examples, we
create a User Mailbox for a user named Oscar B. Hayve.

Creating a New Mailbox in the Exchange Management Console
Creating a new mailbox using the GUI interface of the EMC is easy and familiar to those
who have worked with previous versions of Exchange Server. To do so
1. Start the Exchange Management Console.
2. In the Console Tree, navigate to the Recipient Configuration node.
3. In the action pane, click New Mailbox. The New Mailbox Wizard appears.
Alternatively, administers can select New Mail User, which defaults to creating an
actual user mailbox (as opposed to a room, equipment, or linked mailbox) and
skips step 4.
4. On the Introduction page, as shown in Figure 18.7, select User Mailbox, and then
click Next.
5. On the User Type page, click New User, and then click Next.
6. On the User Information page, complete the following fields:
. Specify the organizational unit rather than using a default one—Select
this box if you want to specify a particular organizational unit. If checked,
click the Browse button and select the desired OU for the user account. For our
example, we leave this box unchecked.
. First name—Type the first name of the user. This field is optional.
. Initials—Type the initials of the user. This field is optional.
. Last name—Type the last name of the user. This field is optional.
. Name—By default, this field is populated with the user’s first name, initials,
and last name, if entered. You can modify the name in this field or type one
manually if no previous fields were populated.
. User logon name (User Principal Name)—This is the name that the user
uses to log on to the mailbox. The user logon name consists of a username
and a suffix. Typically, the suffix is the domain name in which the user
account resides.
. User logon name (pre-Windows 2000)—This is also known as the Security
Account Manager Account Name (SAMAccountName) and is used for Windows
Internet Naming Service (WINS) name resolution. This name must be unique
within the domain and is, by default, automatically populated based on the
preceding User Principal Name.

Password—Type the password that the user must use to log on to his mailbox.
. Confirm Password—Retype the password that you entered in the Password
. User Must Change Password at Next Logon—Select this check box if you
want to require users to reset the password after their first logon (recommended).
7. When finished, click Next.
8. On the Mailbox Settings page, complete the following fields:
. Alias—Enter the desired alias for the user, based on your organization’s policies.
For our example, we use the user’s first initial, middle initial, and last
. Specify the mailbox database rather than using a database automatically
selected—If desired, select this option and use the Browse button to
select a specific database. For our example, we leave this option blank.
. Managed folder mailbox policy—If desired, select this box and click the
Browse button to select the MRM mailbox policy to be associated with this
mailbox. For our example, we leave this option blank.
. Exchange ActiveSync mailbox policy—To specify an Exchange ActiveSync
mailbox policy, select this check box, and then click Browse to select the
Exchange ActiveSync mailbox policy to be associated with this mailbox. For
our example, we leave this option blank.
9. When finished, click Next.

New to Exchange Server 2010 is the Archive Settings page. Selecting the box beside
Create an Archive Mailbox for This Account will, as indicated, create a link to an
online archive for the mailbox. Items will be moved automatically from the primary
user mailbox to the archive based on the default retention policy settings or those
defined by the administrator. For our example, we leave this option blank.
11. On the New Mailbox page, review the Configuration Summary. To make any configuration
changes, click Back. To create the new mailbox, click New.
12. On the Completion page, the summary states whether the mailbox was successfully
created. The summary also displays the Exchange Management Shell command that
was used to create the mailbox. This command can be copied and pasted into a text
editor as the first step toward creating future mailboxes from the command line
interface of the EMS.
13. Click Finish.
