I have a VSTO plugin already that adds some buttons to the Ribbonbar in Outlook 2016 etc and performs some functions.
I now want to add - if possible - a Button to the Toolbar in the Read Pane as seen in the attached image.
Below is some code I found that can hide or show current buttons so I am hoping it is also possible to add a new button.
This new button will just run an existing function in the current VSTO plugin so no fucntion is required. Just to create that button in VB.Net VSTO and to call the current working function.
Need it Now...
