[E2013][MailApp] mailbox.makeEwsRequestAsync GetItem cannot access public folder item RRS feed

  • Question

  • We developed an Office Mail App for Exchange 2013 which needs to read some custom properties of the currently selected mail item.

    We use makeEwsRequestAsync with a GetItem request and that works without problems when the item sits in the current users mailbox.

    When the user added a public folder to his Favorites, selects a message in that folder and activates our Mail App the GetItem request returns an error which contains this:


    The error message is always in german, setting the mailbox language in OWA to en-us didn't change that. This is the error message:

    Mit der Nebenstellennummer sollte nur auf das Act-As-Benutzerpostfach zugegriffen werden.

    Something like: With the extension number you should only access the act-as-user mailbox

    Any ideas how to access public folder items?

    The Public Folder btw is located on Exchange 2013, the same server as the user mailbox.

  • Anything new on this? We're having the same issue when trying to connect to shared mailbox with makeEwsRequestAsync.

    <m:MessageText>Office extension have no permissions to access any other mailboxes then the mailbox provided in the user context.</m:MessageText>
