Hi, I have the following effect with Outlook 2013. I have some Outlook Forms with an Icon and a specific MessageClass that are published to the personal registry. Receiving a new email I eventually change the MessageClass and in the Outlook supergrid the Icon appears. This works fine with Outlook 2010. With Outlook 2013 I have the effect, that the MessageClass is changed, but the corresponding icon is not shown in the supergrid (the icon column is shown on the left). If I reduce the size of the supergrid the position of the icon columns moves automatically from left to right and the icon appears. If I resize Outlook´s Supergrid and the Icon column moves automatically from right back to left, some of the Icons appear, but not all. If I scroll down the Icons are still missing. This effect appears only with Outlook 2013. With Outlook 2010 I never had a Problem. How can I solve this? Thanks Christian.
