If you're working with an item that is not strongly typed, you can always use the base Item class to work with the item. In this article, you'll learn when you can use the generic base class and when you need to use a strongly typed item to complete your task.
The code examples will show you how to use the base class, and what to do when you can't use the base class or it doesn't fit your needs. The EWS Managed API does not have a publicly available constructor for the Item class, so you must use the constructor for the specific item type you want to create in order to create an item. For example, use the EmailMessage class constructor to create a new email message, and the Contact class constructor to create a new contact.
Likewise, the server never returns generic Item objects in responses; all generic items are returned as EmailMessage objects. When you know the type of item to create, you can complete the task in just a few steps. The steps are similar for all item types:. Initialize a new instance of one of the Item classes with the ExchangeService object as a parameter. Set properties on the item.
The schemas are different for each item type, so different properties are available for different items. SendAndSaveCopy method. You can create a generic item or a strongly typed item by using EWS. Use the CreateItem operation to create an item in the Exchange store.
Use the Items element to contain one or more items to create. For example, you can create an email message and send it by using the code in the following example. The server responds to the CreateItem request with a CreateItemResponse message that includes a ResponseCode value of NoErrorwhich indicates that the email was created successfully, and the ItemId of the newly created message. Id of the item to retrieve, you simply call one of the Bind methods on the item, and the item is retrieved.
As a best practice, we recommend that you limit the properties returned to only those that are required. This example returns the item Id property and the Subject property.
This example assumes that service is a valid ExchangeService object and that the user has been authenticated to an Exchange server.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I have a mechanism that downloads attachments from email messages sent into an inbox to a folder for processing by another service. Originally this was done using some VBA that was triggered by a rule in Outlook.
This wasn't build with large amounts of information going in originally however it has got to the point now that lots of data is being passed through and it is causing me headaches using this Outlook VBA and SSIS Package combination.
Therefore I am working on a new version built entirely in VB. NET, this obviously will mean its more robust and a lot easier to debug problems. NET code.
Everything seems to be in C and I unfortunately have no experience with this. I am totally open to 3rd Party Solutions that may need to be purchased or even pointed in the right direction of a book or documentation, this is not being done on a shoe string and is quite important. NET ". The same examples are in C and VB.
Hopefully this will get you started in the right direction. However, I wrote this code carefully, basing it on C code that I know works, because I used it at my workplace. I think it will be a hard delete as well. In other words, you won't be able to pull the emails back out of the Deleted Items folder. You have been warned. It is possible to just mark each email as read instead of deleting it, but I don't have time to write the code for that just now.
Hopefully this will be enough for your needs.The EWS Managed API provides an intuitive, easy-to-use object model for sending and receiving web service messages from client applications, portal applications, and service applications. You can use the open source library to:. We welcome your contributions via GitHub. If you already have an Exchange mailbox account, you can skip this section.

The New Project dialog box opens. Create a C Console Application. If the Solution Explorer window is already open, skip this step and proceed to step 2. In the Solution Explorer and the HelloWorld project, open the shortcut menu right-click for References and choose Add Reference from the context menu. A dialog box for managing project references will open.

Microsoft Graph and the use of OAuth 2. So does this mean that all mobile clients and desktop clients will be forced to use one of these clients?
Will any other clients function or are any on the list above susceptible of not functioning after Basic Auth is disabled? This is another garbage decision that is hostile to customers while providing only modest increases to the massive plague of security issues that haunt O What a boneheaded sense of misdirection that causes customers grief and a never ending churn of updates that provide nearly zero value for many use cases.
I keep wondering what the world will be like for O customers who choose to host their email somewhere else. Sadly it seems the answer to that question is growing more important every day. It is vital that we be able to update contacts on our mobile devices and have them sync to the cloud reliably and transparently, and that contacts modified on other mobile or desktop devices update on all devices.
Will this changes affects plug-ins developed for Outlook windows application accessing Office accounts? Will they not be able to use Outlook Desktop? Kind of sounds like it. I've got to be missing something. We have a 3rd party system which connects through anonymous smtp no login credentials to exchange online. If so, is there a new API that enables the functionality of message-trace and the other very useful reports?
Looking at the notice where the basic authentication will stop working by Octoberi have started to explore the alternative which is moving to Microsoft Graph API. My question is, will the EWS with basic authentication affect the Outlook tasks and calendar events as well? Tasks were out of scope for us but my recall is that the options in the Graph were focused on Planner and To-Do action.
Hello, Is it possible to disable basic authentication earlier, e. We are preparing to implement o and we wanted to check the security features during testing.
