74 Barracuda SSL VPN Administrator’s Guide
Outlook Mobile Access
Exchange 2003 provides a feature called Outlook Mobile Access (OMA). OMA allows users to
access Exchange data by using mobile devices. This browser based application is similar to Outlook
Web Access but much more lightweight and intended for use on cell phones and PDAs.
Configuring the SSL VPN as a OMA Proxy
Configure the Exchange properties as per RPC Client Configuration. All clients that have access to
Outlook using RPC/HTTPS will also have access to the lightweight OMA interface.
Test the connection from a mobile device by simply connecting your cell phone's Web browser to the
following address:
https://<servername>/oma
Outlook Web Access and Mail Check
This mail check feature presents to the user an instant view of his or her email account status directly
through the Manage Account view without having to start their email client to check for new email.
This feature can be used to check for email (and launch your Web mail client) on any mail server that
supports the POP3/IMAP protocols, including Microsoft Exchange.
The mailbox icon is visible from the Manage Account view and shows the status of new or any unread
messages.
Clicking the refresh button also instantly checks the mail account and provides an instant update of
its status. Clicking the mailbox itself will open a new window to the mail account.
Configuration of this relies on a Web forward. The following provides basic steps on how to configure
the mail check feature.
1.
Create a Web forward that connects to the mail server and check that it works correctly. No
username or password has been specified in the configuration. When this Web forward is
launched we will be prompted for authentication.
2.
Configure the mail check configuration parameters from Manage System > Advanced >
Configuration > Mail Checking. The mail check feature requires the OWA server’s details to
access the mail server. Also the mail protocol has been specified and the hostname of the mail
server.
3.
The final step involves the configuration of personal details for each user from the Manage
Account view. For each user the mail check tab becomes accessible from Manage Account > My
Account > Attributes.
The Mail Check feature will automatically try and log onto the mail server with the currently logged
on users credentials. When using Active Directory authentication along with a Microsoft Exchange
mail server these are usually identical. If these are different, then each user needs to provide their
mail authentication details on this screen. In addition the default mail folder (i.e. ‘inbox’) can be
specified if needed.
If the system has been configured to use Active Directory and the mail accounts also uses the same
Active Directory authentication credentials, the mail check extension will automatically use the user’s
Active Directory credentials to authenticate the user’s mail account. There is then no need for users
to provide authentication details in the mail check tab under personal details.
