I have written a FormRegion addin for Outlook (VSTO 2005 SE). It had been working as I expected, but then I change the formRegionType from "replace" to "adjoining" in the manifest. Now GetFormRegionIcon isn't called any more and Outlook doesn't show the my custom icon. What's going wrong? Is this a bug? I only have to change formRegionType...
Thanks, Raul
Adjoining regions appear on the surface of an existing form page and, therefore, don't use icons. Icons apply only to replace and replaceAll regions.
But actually, there is a solution and it's working. I have to register 2 FormRegions. One is only for the icon and one is for the form - declared as adjoining and without any entry for the icon in the manifest:
...
<exactMessageClass>true</exactMessageClass>
<formRegionType>adjoining</formRegionType>
<showInspectorCompose>false</showInspectorCompose>
<showInspectorRead>true</showInspectorRead>
<showReadingPane>false</showReadingPane>
...
2. For showing the icon: a "form region" without a form but with a manifest for the icons and as replaceAll
<exactMessageClass>true</exactMessageClass>
<formRegionType>replaceAll</formRegionType>
<showInspectorRead>false</showInspectorRead>
<showReadingPane>false</showReadingPane>
<showInspectorCompose>false</showInspectorCompose>
<icons>
<default>addin</default>
<read>addin</read>
<unread>addin</unread>
<replied>addin</replied>
<forwarded>addin</forwarded>
<unsent>addin</unsent>
<submitted>addin</submitted>
<signed>addin</signed>
<encrypted>addin</encrypted>
<window>addin</window>
<recurring>addin</recurring>
<page>addin</page>
</icons>

Brilliant! A typical, sneaky Outlook solution. Looking at your manifest, I presume that there is a specific IPM.Note.Something MessageClass involved?
