[Evolution] Un-needed button

[Christopher M <Evolution cwm030 com>]

Hi,

I have a button on my top toolbar on my main Evolution window that
popped up out of no where... I never saw this button when I had evo
installed in KDE yet its here in XFCE.......

How do I make this button go away? I don't see a way to remove it.

I am using Evo 3.28.5

Thanks,
Chris
