Add toolbar button to Meeting tab in Outlook 2013 via VSTO addin

Question

I have searched all over trying to simply find out the correct setting for the OfficeId and RibbonType property of my ribbon so that my ribbon groups are shown on to the built-in "Meeting" tab. I have another ribbon with OfficeId=TabMail and RibbonType=Microsoft.Outlook.Explorer and this works fine to show my ribbon content on the main "Home" tab in Outlook.

I have another ribbon that I want to show on the "Meeting" tab. The tab I'm referring to is the one you see after you double click on a meeting request in your Inbox. The window that opens has a File and Meeting tab at the top. Here is the upper left corner of the window that opens. Inspector Window for Meeting Tab

I've already wasted a lot of time looking at the custom ui help files--that zip file containing all of the available tab ids. I have tried various combinations of OfficeId's and RibbonTypes but nothing works--my ribbon content does not show up. I thought for sure the tab was TabAppointment but now I don't know.

Can someone just please tell me the idMso/OfficeId of that tab? And what should I set the RibbonType property to? I would like for my ribbon content to be displayed on the "MEETING" tab in the window that opens after double clicking a meeting item, AND on the "RECURRING MEETING" tab in the window that opens for a recurring meeting. Here is the screenshot for the window that opens when you double click a Recurring meeting from your inbox. On this one, I want to target the Recurring Meeting tab. Inspector Window for Recurring Meeting

Someone please help!

a screenshot would be great... Try to use TabReadMessage + Microsoft.Outlook.MeetingRequest.Read. — Eugene Astafiev, Apr 17 '15 at 19:26

The below settings works for me on Office 2013, VSTO 4.0, Visual Studio 2013:

OfficeRibbon
RibbonType → Microsoft.Outlook.Appointment

RibbonTab
OfficeId → TabAppointment

RibbonGroup
PositionType → BeforeOfficeId
OfficeId → GroupShow

That's for when you are in full Calendar view. I'm talking about being on the Home tab of the Mail section. You see your list of items in your inbox. Double click on a meeting item and a window opens--it's that window that I want to target, not the full calendar view. – user3487286 Apr 19 '15 at 20:19

I finally figured this out after pulling my hair out for a while. You need to use Microsoft.Outlook.MeetingRequest.Read and TabReadMessage for the idMso of the tab. In hindsight, my main problem is that I was so focused on Meeting/Appointment items and using the wrong tab id's. It did not occur to me that the tab id would be something related to Messages, like TabReadMessage. After spending a lot of time on this issue and doing further research after finally solving this problem, I now understand things better.
