The Exchange Management Pack used by Operations Manager 2007 automatically determines the URL used to monitor the front-end Exchange services. It does this by using a combination of the localhost/network card IP address and the virtual server and virtual directory information in the IIS metabase. This URL is the local monitoring URL because the logon request is submitted to the local front-end server, where the logon request is generated.
You can also supply a custom URL to monitor the public address that is used by Web and mobile devices. To enable monitoring of a custom URL, you must edit the registry on each server where the monitoring is to be enabled.
Configuring a Custom URL for Outlook Web Access (OWA)
To edit the registry, from the Windows Desktop, select Start > Run and type regedit in the textbox. Click the OK button to open the registry editor. Locate the \\HKLM\Software\Exchange MOM\FEMonitoring\<FE servername>\ key and create a registry value of type string named CustomURLs. The custom URL(s) can be entered as a comma-delimited list in this value as follows:
- https://www.mydomain.com/exchange, https://www.mydomain.com/mail
Also, you must set the “CustomURL” override on the Outlook Web Access Logon Monitor to True, which causes the monitor to use the value specified in the new registry key rather than the default values.
Configuring a Custom URL for Outlook Mobile Access (OMA)
Navigate to the same registry key listed above for configuring a custom URL for Outlook Web Access (OWA). Create a registry value of type string named CustomOmaUrls. The custom URL(s) can be entered as a comma-delimited list in this value as follows:
- https://www.mydomain.com/oma, https://www.mydomain.com/mobile
Also, you must set the “CustomURL” override on the Outlook Mobile Access Monitor to True, which causes the monitor to use the value specified in the new registry key rather than the default values.
Configuring a Custom URL for Exchange ActiveSync
Navigate to the same registry key listed above for configuring a custom URL for Outlook Web Access (OWA). Create a registry value of type string named CustomEasUrls. Enter the custom URL in this value as follows:
- https://www.mydomain.com/Microsoft-Server-ActiveSync
Also, you must set the “CustomURL” override on the Exchange Active Sync Monitor to True, which causes the monitor to use the value specified in the new registry key rather than the default values.
