How to change the size of commandbar button icon displayed in Outlook 2010 ribbon?

We are adding Outlook 2010 support to our 2007 addin that is using a CommandBar.

The problem is that the icon is very small (compared to the ribbon) - the 16px version is used, despite the fact that the Icon itself has also the 64px size embedded.

commandBarButton initialization code:

      private AddinExpress.MSO.ADXCommandBarButton commandBarButton;

      this.commandBarButton.Caption = "Caption";
      this.commandBarButton.ControlTag = "958574F9-9616-4d40-982A-A51DF169DFEC";
      this.commandBarButton.DisableStandardAction = true;
      this.commandBarButton.Image = 0;
      this.commandBarButton.ImageList = this.imgList;
      this.commandBarButton.ImageTransparentColor = System.Drawing.Color.Transparent;
      this.commandBarButton.St yle = AddinExpress.MSO.ADXMsoButtonStyle.adxMsoButtonIcon;
      this.commandBarButton.Temporary = true;
      this.commandBarButton.UpdateCounter = 17;
      this.commandBarButton.Click += commandBarButton_Click;

How to ensure that the ribbon-contained commandbar button will be bigger when displayed in Outlook 2010?

Hi Marek,

Being Ribbon-controlled, that button still conforms to the command bar rules (well, to most of them) and this is why you see the issue. I suggest that you add a Ribbon button onto your add-in module and set UseForRibbon=False in the command bar component that shows the commandBarButton above.

Also, may want to look at MS Office toolbar and Ribbon UI images style guide.
