Description

Users often visit Web sites or receive email messages with embedded Mailto links. This article provides information on the configuration of published Microsoft Outlook for content redirection of MailTo URLs.

Instructions

Complete the following steps to configure Microsoft Outlook for content redirection of MailTo links:

Caution! Refer to the Disclaimer at the end of this article before using Registry Editor.

In the registry of each server where Microsoft Outlook is published, edit the Data value for the Default string label so that it matches the following: "C:\Program Files\Microsoft Office\OFFICE11\OUTLOOK.EXE" /c IPM.note /m "%1"
Location in REGEDIT - HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Microsoft Outlook\shell\open\command
Modify the Location section of the Microsoft Outlook Properties to the following:
“C:\Program Files\Microsoft Office\OFFICE11\OUTLOOK.EXE” “”%xx”
Modify the Content Redirection section of the Microsoft Outlook Properties to following:
Test the configuration with the following html code. Paste the code into Notepad and save the file with an .html extension.
<html>
<body>
<p>
<h2>MailTo Test...</h2>
<p>
<a href="mailto:joe.smith@msbx.net?subject=MailTo%20With%20Spaces%20Test">MailTo with Subject and Spaces Test</a>
</body>
</html>
Launch XenApp (Program Neighborhood Agent), open the html page, and click the MailTo link. Microsoft Outlook launches and a compose Window appears as shown in the following screen shot:

Note: Some URLs do not conform to RFC 1738, which recommends that spaces in URLs are encoded using %20 and these links might not display the desired result when a user clicks the link and content redirection is enabled. For example, a MailTo link with a pre-defined subject that contains spaces rather than the recommended encoding shows the following error message when the link is clicked and Outlook launches.

This error message appears because Microsoft Outlook sees the space as an argument separator for the command line (switch). This is not a failure of the content redirection feature.
