title: Create a custom button with icon in a custom group for Outlook using C# VSTO
body: <p>I am fairly new to C# as well as the Outlook Library. </p>
  
  <p>I have created a custom group in Meeting Tab of Outlook, which has a button in it.
  I also added an image in properties of Button(as displayed in the screenshot).</p>
  
  <p><a href="https://i.stack.imgur.com/b3GLr.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/b3GLr.png" alt="enter image description here"></a></p>
  
  <p>The image would represent the logo of my add-in. But I'm not able to change the size of that image.</p>
  
  <p>I want my button to look similar to that of other buttons of Outlook just like 'Skype Meeting' or 'Meeting Notes' with the larger icon.</p>
  
  <p>Can anyone please suggest me the way to design the Button with large icon.</p>
  
  <p>I have created the Ribbon (Visual Designer) in Visual Studio 2015 for Outlook 2016 Add-In using VSTO. What would be the best way to do this using C#?</p>
