title: Make Outlook add-ins working with Office 365 shared mailboxes
body: <p>I am building apps with the new technology of Office add-ins (formerly app for Office).</p>
  
  <p>The add-ins activate well when registered globally for the Office 365 tenant or individually by user (mechanical gear > manage add-ins).</p>
  
  <p>I would like my add-in to work with Office365's shared mailboxes. The add-ins do not load in Outlook desktop or in OWA when the shared mailbox is open alone.</p>
  
  <p>However, I managed to make it work when setting the shared mailbox as a shared folder displayed under my primary mailbox, as explained <a href="https://support.office.com/en-US/article/Open-and-use-a-shared-mailbox-in-Outlook-Web-App-BC127866-42BE-4DE7-92AE-1EF2F787FD5C" rel="noreferrer">here</a> (see picture below). It is better than nothing but not an acceptable solution, I would like my add-ins to be displayed when consulting my mailbox in Desktop client and in OWA when using the "Open another mailbox" (see link above).</p>
  
  <p>My question is then: how to make add-ins working with shared mailboxes? A possible solution is: a shared mailbox seems to be related with a special kind of user. Would it be possible to install the add-in for this special user in order to have the add-ins always working with shared mailboxes?</p>
