Different behaviour of Outlook (client) and OWA when sending mails RRS feed

  • Question

  • Hi everyone,

    we're developing an application which uses the push notifications of the Exchange systems to communicate (and synchronize) with the server.

    We're currently facing the following problem: we want to create a mail in the drafts folder of a user via EWS (working fine) and when the user sends this mail, we want to be notified in order to look for changes made to the mail (in order to keep our own "mail object" updated). The problem is, the Outlook client is sending a move-Notification from Draft to Sent Items whereas the OWA creates a Delete- and a Create-Notification.

    Is there a reason for this difference? Is there a way to change it / is the change planned for future releases? Right now our application is only handling the move-Notification and since this application is running on a server for a number of users, we don't want to create too many notification subscriptions which all have the same callback URL.

    Thank you in advance and kind regards,
