Add a button to the attachment menu using Outlook Addin

I'm writing an office.js Outlook addin and I want to add a button to the attachments menu

In owa the menu is here

enter image description here

In desktop it would be here

enter image description here

I have implemented the option on a task pane but it work better if the attachment had already been selected and they pick my option from the attachment rather than click the button on the Mail Read task pane and then have to select from a list of attachments

Thanks

I have looked through the documentation but can't see the option exists.

Solution

  • The UI extenstion points are defined in the add-on's manifest file. Current list of Extension points for Outlook doesn't provide any extansibility to the attachment context menu.
