Outlook Web add-in: Is it possible to close the inspector window by add-in?

Question

I'm now developing an outlook web add-in. One of the feature is to move the email to trash. However, the behaviour of the add-in in outlook 2016 and OWA seems different.

When I double-click the email to open the inspector window and perform the add-in delete function:

OWA: the inspector window will close automatically

Outlook 2016: the inspector window will not close

As I want to achieve the same result in Outlook 2016 and OWA, I would like to know if any method can close the inspector window.

My add-in to delete the email is using EWS SOAP API "MoveItem". OWA works perfect but Outlook 2016 will not close the inspector window after delete. I have tried to use the Office.js function "Office.context.mailbox.item.close()" but it seems only work for compose item.

Answer 1

That is unfortunately the current behavior. I've encountered the same issue with my add-in and had to adjust by displaying a message to the user that they will have to close the window after my code moves the email to another folder.
