My UltraExplorerBar use style OutlookNavigationPane and ViewStyle Office2003 is very smart and beautiful. But when I set ViewStyle to office2007, it look very bad: group and Item always have double border line. So it isn't as beautiful as MS Outlook 2007.
I try to find solution to set Group, Item border to single but I can't. Well, I still use style Office2003 for my Product [:'(]
I wonder UltraExplorerBar style Office2007 will more beautifully in next release?
I can't comment on the aesthetic appeal of the Office2007 view style since it is subjective, but UltraExplorerBar's Office2007 style is almost exactly a pixel-by-pixel replica of the Outlook2007 component after which it was patterned. My suspicion is that you have some appearance properties set that you are possibly not aware of and these are conflicting with the default values used by the control. You might want to provide a screen shot and/or log an incident with Developer Support so we can try to figure out what is causing the control to look the way it does.
I haven't set any property, only use Style and ViewStyle. Here are picture to compare:
