Hello

I need to add a single button in the Attachments tab.

In https://github.com/MicrosoftDocs/visualstudio-docs/issues/6770#issuecomment-866319992 I see that there is a link https://www.microsoft.com/en-us/download/confirmation.aspx?id=50745 where you can download a file with the internal IDs.

In OutlookMailReadControls.xls I see there is a TabAttachments id. So I added it in the officeId field :User's image

)

But in the Attachmens menu I don't see anything:

User's image

If I change the id to TabReadMessage then it works but I really need it to be added to the Attachments tab.

I guess there is something bad with the id. Do you have the correct ID

Thanks
