A Dart client library to access Microsoft Exchange web services. The library works against Office 365 Exchange Online as well as on premises Exchange.
This project is a Dart client library to access Microsoft Exchange web services. The library works against Office 365 Exchange Online as well as on premises Exchange. By using it you can access almost all the information stored in an Office 365, Exchange Online, or Exchange Server mailbox. However, this API is in sustaining mode, the recommended access pattern for Office 365 and Exchange online data is Microsoft Graph
Getting started #
In the library the ExchangeService class contains the methods and properties that are used to set user credentials, identify the Exchange Web Services endpoint, send and receive SOAP messages, and configure the connection with Exchange Web Services. To perform an operation by using the library, you must set up the ExchangeService class.
final service = ExchangeService.withVersion(ExchangeVersion.Exchange2007_SP1) ..Url = Uri.parse("https://outlook.office365.com/ews/exchange.asmx") ..Credentials = WebCredentials("---USER_NAME---", "---USER_PASSWORD---", "---USER_DOMAIN---");
Creating folders #
The following code example shows how to create a folder with a custom folder class.
final folder = new Folder(service) ..DisplayName = "Custom Folder" ..FolderClass = "IPF.MyCustomFolderClass"; await folder.SaveWithWellKnownFolderName(WellKnownFolderName.Notes);
Creating custom extended properties #
The following code example shows how to create a new extended property, set a value for the extended property, and add it to a message.
// Create a definition for the extended property. final extendedPropertyDefinition = ExtendedPropertyDefinition.withDefaultPropertySetAndName(DefaultExtendedPropertySet.Common, "custom:MeetingDescription", MapiPropertyType.String); // Create an e-mail message that you will add the extended property to. final message = new EmailMessage(service) ..Subject = "Saved with the meeting description" ..Body = MessageBody.withText("The meeting description is contained within the extended property.") ..ToRecipients.Add(EmailAddress(smtpAddress: "email@example.com")) ..SetExtendedProperty(extendedPropertyDefinition, "The meeting purpose is make the right decision"); // Save the e-mail message. await message.SendAndSaveCopy();
Creating an appointment #
The following code shows how to create an appointment and set a subject, a body, a start time, and an end time to one.
final startTime = new DateTime(2019, 9, 9, 9, 10, 0); final appointment = new Appointment(service) ..Subject = "Dentist Appointment" ..Body = MessageBody.withText("The appointment is with Dr. Smith.") ..Start = startTime ..End = startTime.add(Duration(hours: 2)); await appointment.SaveWithSendInvitationsMode(SendInvitationsMode.SendToNone);
