4.2 Mail App Configuration Data

  • Article

The mail add-in requests access to its configuration data. The identifier for the mail add-in is "urn:uuid:{4b8686f0-1b40-11e1-bddb-0800200c9a66}".

The client opens the configuration data message with the value "IPM.Configuration.ClientExtension.4b8686f01b4011e1bddb0800200c9a66" in the PidTagMessageClass property ([MS-OXCMSG] section 2.2.1.3). The client checks the value of the PidTagRoamingDictionary property ([MS-OXOCFG] section 2.2.2.2) on the configuration data message and finds the following XML document.

 <?xml version="1.0"?>
 <UserConfiguration>
     <Info version="Outlook.15"/>
     <Data>
         <e k="18-ExtensionSettings" v="18-{&quot;application_setting_name_1&quot;:&quot;\&quot;application_setting_1\&quot;&quot;,&quot;application_setting_name_2&quot;:&quot;\&quot;application_setting_2\&quot;&quot;,&quot;application_setting_name_3&quot;:&quot;\&quot;application_setting_3\&quot;&quot;}"/>
         <e k="18-OLPrefsVersion" v="9-1"/>
     </Data>
 </UserConfiguration>

The value of the "ExtensionSettings" name/value pair is extracted as follows.

 {"application_setting_name_1":"\"application_setting_1\"",

 "application_setting_name_2":"\"application_setting_2\"",

 "application_setting_name_3":"\"application_setting_3\""}
