How to share schedules using the ews protocol

Hi,Welcome to the Microsoft Q&A forum.

Here’s a overview of how you can do that:1. Set up EWS Managed API: First, you need to install and set up the EWS Managed API. You can download it from the Microsoft website or use NuGet to install it into your project.

2. Authenticate: Establish a connection to the Exchange server using proper authentication credentials.
3. Create and Send Sharing Invitation:
   • Create a Calendar Folder: If you don't already have a calendar folder to share, you can create one.
   • Create Sharing Invitation: Use the CreateSharingInvitation method to generate a sharing invitation for the calendar.
   • Send Sharing Invitation: Send the sharing invitation to the intended recipient.

Here is a basic example in C#:

using Microsoft.Exchange.WebServices.Data;

class Program

{

    static void Main(string[] args)

    {

        ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013);

        service.Credentials = new WebCredentials("your_username", "your_password", "your_domain");

        service.Url = new Uri("https://your_exchange_server/EWS/Exchange.asmx");

        // Create a calendar folder

        Folder calendarFolder = new Folder(service);

        calendarFolder.DisplayName = "Shared Calendar";

        calendarFolder.FolderClass = "IPF.Appointment";

        calendarFolder.Save(WellKnownFolderName.Calendar);

        // Create a sharing invitation

        FolderPermission permission = new FolderPermission("recipient_email@example.com", FolderPermissionLevel.Reviewer);

        calendarFolder.PermissionSet.Permissions.Add(permission);

        // Send sharing invitation

        CalendarFolder calendar = CalendarFolder.Bind(service, WellKnownFolderName.Calendar);

        calendar.Save();

        Console.WriteLine("Sharing invitation sent.");

    }

}

Replace placeholders like "your_username", "your_password", "your_domain", and "your_exchange_server" with your actual Exchange server details and credentials.
