Good morning, Thomas. Welcome to office.developer.com.add_ins newsgroup! My
name is Jialiang Ge [MSFT].



I once handled a very similar issue, where a customer said his
CommandBarButton icon cannot be shown only in Outlook 2000. That problem
turned out to be caused by the code:

HBITMAP hSrcBmp = LoadBitmap(AfxGetResourceHandle(),

MAKEINTRESOURCE(IDB_BITMAP1));

The method LoadBitmap has been superseded by the LoadImage function because
it is incompatible with some device context. Thus, the resolution was to
replace the line with:

HBITMAP hSrcBmp = (HBITMAP)::LoadImage(GetModuleHandle(NULL),

MAKEINTRESOURCE(IDB_BITMAP1), IMAGE_BITMAP,0,0,LR_CREATEDIBSECTION);



Thomas, because you did not mention how you loaded the bitmap icon or
provided any code snippet for test, I cannot quickly figure out the reason
for this specific issue. But I suggest you read the above-mentioned thread:

http://office-outlook.com/outlook-forum/index.php/m/209360/#msg_209360



And if the thread does not help, would you please show us some code
snippets? I'd be very happy to test it for you.



Regards,
