The Office365 class provides an easy way to manage sending and receiving mail in Microsoft 365.

Syntax

cloudmail.Office365

Remarks

This class provides an easy to use interface for Office365 using the Microsoft Graph API v1.0. To use the class, first set the Authorization property to a valid OAuth token. The Office365 class can be used for sending or creating new messages; retrieving, moving, or copying existing messages; creating, deleting, or copying folders; and several other functionalities supported by the Microsoft Graph API.

This class requires authentication via OAuth 2.0. First, perform OAuth authentication using the OAuth class or a separate process. Once complete you should have an authorization string which looks like:

Bearer ya29.AHES6ZSZEJzATdZYjeihDn5W-VrXSsxEZu5p0pclxGdKKQ
Assign this value to the Authorization property before attempting any operations. For Example:
Oauth oauth = new Oauth();
 
oauth.ClientId = "3c65828c-6376-4286-91b5-2381c3904a97"; 
oauth.ClientSecret = "fMI7Q~SmDkDGujXXQkKtaNE5hBQID0SIBmmwP";
oauth.ServerAuthURL = "https://login.microsoftonline.com/common/oauth2/v2.0/authorize";
oauth.ServerTokenURL = "https://login.microsoftonline.com/common/oauth2/v2.0/token";
oauth.AuthorizationScope = "user.read mail.readwrite mail.send mailboxsettings.readwrite";
oauth.GrantType = OauthGrantTypes.ogtAuthorizationCode;
 
office365.Authorization = oauth.GetAuthorization();
Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.

Sending Messages

There are two methods for sending new messages using the Office365 component. The SendMail method will send a message directly. Alternatively, you can create a message draft and then send an existing draft using the SendDraft method. In both cases the properties of the new message are assigned through the Message properties (MessageSubject, MessageBodyContent, MessageCc, etc.).

Sending a Message with SendDraft:

office365.MessageSubject = "Subject Text";
office365.MessageImportance = "Low";
office365.MessageBodyContentType = "TEXT";
office365.MessageBodyContent = "Body Text.";
office365.MessageTo = "email@example.com";

office365.CreateDraft(0, "");
string messageId = office365.MessageInfo[0].Id;

office365.SendDraft(messageId);

There are also methods for replying or forwarding messages using the Office365 component. The Reply, ReplyAll, and Forward method will send a reply or forward directly. Similarly, you can create a reply or forward draft and then send an existing draft using the SendDraft method. Unlike creating a new message, only the direct methods use the Message properties (MessageSubject, MessageBodyContent, MessageCc, etc.). When using CreateDraft, the draft must first be made then updated using the MessageInfo collection and Update method.

Sending a Reply with SendDraft:

//Create the reply draft
string originalMessageId = "Message ID";
office365.CreateDraft(1, oringialMessageId);

//Set the new draft MessageInfo fields with desired options
office365.MessageInfo[0].To = "email@example.com";
office365.MessageInfo[0].Subject = "Subject Text";
office365.MessageInfo[0].BodyContentType = "TEXT";
office365.MessageInfo[0].BodyContent = "Body Text";

//Update the draft
office365.Update(office365.MessageInfo[0].Id);

//Send the draft
office365.SendDraft(office365.MessageInfo[0].Id);

Receiving Messages

Information about messages fetched by the component can be accessed through the MessageInfo collection. MessageInfo collection is populated when the ListMessages, FetchMessage, Search, or ListChanges methods are called.

The ListMessages and ListChanges methods will respectively list the messages or changed messages in a folder specified by a folderId. To get the ID of a folder, folders can be traversed and read using the ListFolders method and the Folders collection.

Listing Messages in a Folder:

// Get the folder ID
string folderId = "";

office365.ListFolders(""); // Lists the root child folders.

for (int i = 0; i < office365.Folders.Count; i++)
{
  if (office365.Folders[i].DisplayName.Equals("SpecificFolderName"))
  {
    folderId = office365.Folders[i].Id;
    break;
  }
}

// List folder messages
office365.ListMessages(folderId, "");

By default, the component will fetch one page of 100 messages when ListMessages is called. If additional messages remain in the folder, the ListMessagesMarker property will be populated. If ListMessages is then called again on the same folder the next page of messages will be fetched. The example below populates MessageInfo collection with all the messages in a particular folder.

do {
  office365.ListMessages(folderId);
} while (office365.ListMessagesMarker.Length > 0);

The message page size may also be changed by using the MessagePageSize configuration setting.
