I want my tab to be shown on several ribbon types in Outlook 2010: Microsoft.Outlook.Mail.Compose, Microsoft.Outlook.Post.Compose, Microsoft.Outlook.Response.Compose, Microsoft.Outlook.Sharing.Compose.
Currently it's shown only on Microsoft.Outlook.Mail.Compose though I selected all types above in designer.
What else I should do to apply me tab for all these ribbons?
And I've just noticed that my tab is not appear if I'm creating new rich text message (Email message using -> Rich text). Why?
