VSTO Outlook: Add a new explorer column with a predefined Outlook icon (PR_ICON_INDEX)

I am trying to create a new column in explorer. I would like this column to contain one of the predefined Outlook icons using PR_ICON_INDEX.

So I am looping over all Outlook mail items and set their property PR_ICON_INDEX using below method:

    private const int OL_PHONE = 0x15D;
    private const string PR_ICON_INDEX = "http://schemas.microsoft.com/mapi/proptag/0x10800003";

    private bool SetExtendedPropertyValue(Outlook.MailItem aMailItem, string aProperty, int value)
    {
        Outlook.PropertyAccessor oPropAcc = null;
        try
        {
            oPropAcc = aMailItem.PropertyAccessor as Outlook.PropertyAccessor;
            oPropAcc.SetProperty(aProperty, value);

            return true;
        }
        catch (System.Exception ex)
        {
            //Put your own logging here
        }
        finally
        {
            if (oPropAcc != null)
            {
                Marshal.ReleaseComObject(oPropAcc);
                oPropAcc = null;
            }
        }

        return false;
    }

For example, in some point in my code I call this method like below:

SetExtendedPropertyValue(mi, PR_ICON_INDEX, OL_PHONE);

Also I have replaced the active explorer CurrentView.XML with a custom view but when I call to CurrentView.Apply() after setting the XML I get below exception:

The operation failed

The custom view I am trying to set is below (not working):

<?xml version="1.0"?>

However below XML view is working:

<?xml version="1.0"?>
<view type="table">
    <viewname>myView</viewname>
    <viewstyle>table-layout:fixed;width:100%;font-family:Segoe UI;font-style:normal;font-weight:normal;font-size:8pt;color:Black;font-charset:0</viewstyle>

        <type>i4</type>
        <width>1190</width>
        <style>padding-left:3px;text-align:left</style>
        <editable>0</editable>
        <displayformat>3</displayformat>
        <userheading/>
    </column>
    <column>
        <heading>Categories</heading>
        <prop>urn:schemas-microsoft-com:office:office#Keywords</prop>
        <width>50</width>
        <sortable>0</sortable>
        <style>text-align:left;padding-left:3px</style>
        <editable>1</editable>
    </column>
    <column>
        <heading>Mention</heading>
        <prop>urn:schemas-microsoft-com:office:outlook#at-me-flag</prop>
        <type>boolean</type>
        <autoresize>0</autoresize>
        <width>50</width>
        <sortable>0</sortable>
        <style>text-align:center;padding-left:3px</style>
        <editable>0</editable>
        <format>boolicon</format>
        <displayformat>3</displayformat>
    </column>
    <groupbydefault>2</groupbydefault>
    <previewpane>
        <visible>1</visible>
        <markasread>0</markasread>
    </previewpane>
</view>

The difference between both XML views is the following (first view has defined below column and the second hasn't):

    <column>
        <heading>Status</heading>
  <prop>http://schemas.microsoft.com/mapi/proptag/0x10800003</prop>
        <bitmap>1</bitmap>
        <style>padding-left:3px;;text-align:center</style>
        <editable>0</editable>
    </column>

So the problem comes with above column definition. It refers to the property PR_ICON_INDEX. It looks like there is something that Outlook does not like.

So what am i doing wrong?

Look at what Outlook itself is using:

<column>
    <heading>Icon</heading>
    <prop>http://schemas.microsoft.com/mapi/proptag/0x0fff0102</prop>
    <bitmap>1</bitmap>
    <width>18</width>
    <style>padding-left:3px;;text-align:center</style>
    <editable>0</editable>
</column>
