New Post: Show Ribbon-Tab only in Main-Window (Outlook Addin)

Dear together

I've successfully developed a Outlook Addin with NetOffice (nearby a great piece of software..). Now the Ribbon is always visible also inside new messages etc.

Is there a way to display the Ribbon only on the Main Window and not inside elements like calendar entries or memos?

I've played arround with the getVisible possibility inside the RibbonUI.xml and was able to hide the ribbon but could not figured out how to determine if the current "Window/Form" (whatever) is the Main Window or a new Message etc..

Does anyone have a input for me, where to serach or probably has a solution for my kind of question?

Thanks for your inputs.

regards
