List of Cancelled or Deleted meetings RRS feed

  • Question

  • Is there any way to get a list of Cancelled or Deleted meetings in EWS?

    I'm trying to make integration with our CRM system and need a way to track meeting deletion and meeting cancellation in Exchange 2010.

    If it’s not possible to get a list of Cancelled or Deleted meetings, please, advice any way to sync meeting cancellations, checking existence by Guid seems to be not good because of performance problems.

    Depending on how a user deletes an appointment (or any item), different things are done:

    • Soft-Delete: The item is moved to the recycle bin of the mailbox.
    • Hard-Delete: The item is instantly removed.

    You have multiple ways to get information about deleted items:

    • Query the folder using a FindItems call and select ItemTraversal.Associated in the Traversal property of the ItemView. Note: This requires Exchange 2010.
    • Use the SyncFolderItems at one time and store the synchronization cookie somewhere. Later, execute the SyncFolderItems again using the previously stored cookie. Exchange will now give you a detailed list of changes which happened to the folder.
    • Query the Recycle bin for appointments. They will most likely have come from the default calendar of the user.
