    SUMMARY

    The Microsoft Exchange client for Windows has an option under Tools, Inbox Assistant, Add (or Edit) rule, called Custom. This dropdown box is typically blank unless custom rules have been defined. It is available for the Microsoft Exchange Server developer to create a custom rule using the Microsoft Exchange Software Development Kit (SDK).

    MORE INFORMATION

    The custom dropdown option will use an entry in the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\Client. Specifically, the Microsoft Exchange client is looking for a Custom Actions key that is not available by default. Under this key, corresponding values for a rule processing .DLL file are included (this .DLL is created using the SDK). The following example illustrates this using an example found in the SDK under the registry value used for the above key called Launch: 

       4.0;c:\windows\system32\crarun.dll;1;00000101001100
    With the registry entry and rule processing .DLL correctly configured, the user can then check the custom option and select the name displayed (in this case, Launch) from dropdown list to customize Inbox rule processing for the Microsoft Exchange client.

    For more information regarding custom rules, see the Readme.wri and Crarun sample available with the Microsoft Exchange SDK. A sample that utilizes a custom rule is available to the public on the Internet at:

    Look under the Miscellaneous Tools section, Launcher Custom Action and ExPrint.
