Hi,
I have added image to a cell in OutLookExpressMode using m_ultraTreeNode.Cells[item.ColumnIndex].Appearance.Image = item.CellImage; While displaying the image it is showing a white patch around the image. I have set m_ultraTreeNode.Cells[item.ColumnIndex].Appearance.BackColorAlpha = Infragistics.Win.Alpha.Transparent; Even then the white patch is appearing. Is there any other solution to remove the white patch. I have provided the image here to have a look.

The control exposes an ImageTransparentColor property which you can use to override the default transparent color (which is of course Color.Transparent). Assuming that the background of the image is exactly RGB(255, 255, 255), you can assign Color.White to the ImageTransparentColor property.
