Mails from Sent Item folder not getting synced in Exchange Web Service 2010

We are using the EWS API (2010) with usage : SubscribeToPullNotifications ( FolderIDs, 300, CurrentWatermark, EventType.NewMail ) to read the emails from an exchange account into our program. However, even though the folder ids that are sent unique to each folder, when the email events are received back, i gets only the events from all folders except Sent Items folder.

The complete flow which i am using :

  • Initial Sync : All folders [including sent items] ) are synced along with their mails. This information is stored to DB.
  • Subsequent sync : The unique folder ids, along with the water mark received is sent for taking the next / updated batch of mails. (This doesn't give sent items folder mails).

Did any one face this issue ?. Do i need to do any extra steps to ensure the sent items folders are also synced and their mails are received in.

Are you confident that the sent items folder has actually changed between initial and subsequent sync? – Tom Makin

Your subscribing to the EventType.NewMail event this event only occurs when new email is delivered to the Inbox. When somebody sends an Email a copy of that email is saved to the SentItems folder but this won't trigger the NewMail event because its not a delivery its just a creation so you need to also listen for EventType.Created to pickup new emails that are added to the SendItems folders.

A good tool to test this with is the EWSEditor https://ewseditor.codeplex.com/ it will let you subscribe to all events and you can then see exactly what event occurs when actions are taken on a Mailbox without needing to write any code.
