How to set a custom Icon of an Outlook folder?

Question

Is there any way to set a custom Icon of an Outlook folder or subfolder using Outlook object model?

Answer 1

From what I have read this is unfortunately not possible in Outlook 2007.

It is possible in Outlook 2010 using MAPIFolder.SetCustomIcon. See MSDN for more details: http://msdn.microsoft.com/en-us/library/ff184775.aspx

Switching the list of MAPIFolder methods between 2010 and 2007 on the following MSDN webpage shows the SetCustomIcon method for 2010 only: http://msdn.microsoft.com/en-us/library/bb645002.aspx
