Microsoft Exchange Server 2007 will reach end of support on April 11, 2017. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
Applies to: Exchange Server 2007, Exchange Server 2007 SP1, Exchange Server 2007 SP2, Exchange Server 2007 SP3
This topic describes how to configure Windows Basic authentication for Microsoft Office Outlook Web Access in Microsoft Exchange Server 2007. Basic authentication sends the user's logon name and password in clear text and should not be used without using Secure Sockets Layer (SSL) encryption between the client computers and the computer that has the Client Access server role installed. Basic authentication is supported on Microsoft Exchange Server 2003 and Exchange 2007.
Before You Begin
To perform this procedure, the account you use must be delegated the Exchange Server Administrator role and membership in the local Administrators group for the target server.
For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.
The exact steps that you perform when you complete this procedure by using the Exchange Management Console depend on the following:
Whether you are running the original release (RTM) version of Exchange 2007 or Exchange 2007 SP1.
Whether you are running the Mailbox server role on the computer that is running the Client Access server role.
For detailed information about these differences, see Managing Outlook Web Access Virtual Directories in Exchange 2007.
Procedure
Exchange 2007 SP1
To use the Exchange Management Console to configure Basic authentication for Outlook Web Access
In the Exchange Management Console, locate the virtual directory that you want to configure to use Basic authentication by using the information in step 2 or step 3.
If you are running the Mailbox server role on the computer that is running the Client Access server role, do one of the following:
To modify an Exchange 2007 virtual directory, select Server Configuration, select Client Access, and then click the Outlook Web Access tab. The default Exchange 2007 virtual directory is /owa.
To modify a legacy virtual directory, select Server Configuration, select Mailbox, and then click the WebDAV tab. The default legacy virtual directories are as follows: /Public, /Exchweb, /Exchange, and /Exadmin.
If you are not running the Mailbox server role on the computer that is running the Client Access server role, select Server Configuration, select Client Access, and then click the Outlook Web Access tab.
In the work pane, select the virtual directory that you want to configure to use Basic authentication, and then click Properties.
Click the Authentication tab.
Select Use one or more standard authentication methods.
Select Basic authentication.
Click OK.
To use the Exchange Management Shell to configure Basic authentication for Outlook Web Access
To configure Basic authentication on the default Outlook Web Access virtual directory in the default Internet Information Services (IIS) Web site on the local Exchange server, open the Exchange Management Shell and run the following command:
Set-OwaVirtualDirectory -Identity "owa (Default Web Site)" -BasicAuthentication <$true|$false>
For more information about syntax and parameters, see Set-OwaVirtualDirectory.
