Don't adjust your mind - it's reality that is malfunctioning

OWA Options dialog from a programmers perspective


Outlook Web Access can be configured to some extent by the means of a settings page. This page is opened when you click Options in the main menu. However, Microsoft lacks documentation about which properties within the store reflect these settings.
All the properties below are stored on the root folder of a mailbox.
Here is an example that gets the current timezone setting from the administrators mailbox:

    1 PROPFIND /exchange/administrator

    2 Host:

    3 Translate: f


    5 <?xml version="1.0" encoding="utf-8" ?>

    6 <a:propfind xmlns:a="DAV:">

    7   <a:prop>

    8     <timezone xmlns="" />

    9   </a:prop>

   10 </a:propfind>

The properties

All the affected properties are within the namespace.
