VSTO C#: How to disable the popup (tooltip) on a Ribbon Button

I developed a plugin for outlook 2007 that adds a button to the office ribbon.

I wanted to know if there is any possibility (programmatically) to not show the popup message when hoovering over the button with the mouse pointer.

When I hover over the button, a little popup (toolt开发者_开发知识库ip) with the following text is displayed: MyAddinName Press F1 for help

Is there any way to suppress this message for this custom button?

It's not possible to remove that text. Microsoft puts it there so that third-party add-ins are clearly identified and their product doesn't get blamed for buggy behavior.
