通过 EWS（Exchange WebServices）获取所有邮箱 - 不是我自己的邮箱，也包括共享邮箱和群组邮箱

发布于 2025-01-05 12:31:07 字数 463 浏览 3 评论 0原文

谁能给我提供一个 .NET (C# / VB) 示例，说明如何获取我有权访问的所有邮箱？

我只能通过 EWS 获取自己的邮箱 - 而不能通过 Outlook 访问所有其他邮箱。

我没有这些邮箱的名称和 ID，但是否可以检索我可以查看的所有邮箱（包括我自己的邮箱），就像在 Outlook 中一样？

我正在使用自动发现来获取我的邮箱，如下所示： service.AutodiscoverUrl("[电子邮件受保护]") - 这可能只会获取我自己的邮箱，而不是其他邮箱？

请帮忙！？

我解决这个问题的方法是将有问题的组邮箱定义为“邮箱”对象，然后获取特定文件夹的FolderID。

定义邮箱对象

邮箱 gpmailbox = new 邮箱("[电子邮件受保护]");

获取FolderID（在本例中为收件箱）

FolderId gpInbox = new FolderId(WellKnownFolderName.Inbox, gpmailbox);

在普通代码中使用FolderID（在本例中我获取了100 条消息）

ItemView 视图 = new ItemView(100);        
FindItemsResults<项目>结果 = hookToServer.FindItems(new FolderId(WellKnownFolderName.Inbox, gpmailbox), view);

关键是获取您需要的文件夹的FolderID。希望这有帮助。

编辑：我也没有注意到我的对象“hookToServer”只是 ExchangeService 对象。我是这样定义的：

        ExchangeService hookToServer = new ExchangeService(ExchangeVersion.Exchange2010_SP1);
        hookToServer.UseDefaultCredentials = true;
        hookToServer.Url = new Uri("TheExchangeServer")

我也用这个作为参考：
EWS 2007 群组邮箱指南

The way I got around this was to define the group mailbox in question as a "mailbox" object and then obtain the FolderID for the particular folder.

Define mailbox object

Mailbox gpmailbox = new Mailbox("[email protected]");

Get the FolderID (in this case, the Inbox)

FolderId gpInbox = new FolderId(WellKnownFolderName.Inbox, gpmailbox);

Use FolderID in your normal code (in this case I'm obtaining 100 messages)

ItemView view = new ItemView(100);        
FindItemsResults<Item> results = hookToServer.FindItems(new FolderId(WellKnownFolderName.Inbox, gpmailbox), view);

The key is to grab the FolderID of the folder you need. Hope this helps.

Edit: I also failed to note that my object "hookToServer" is simply the ExchangeService object. Here's how I defined it:

        ExchangeService hookToServer = new ExchangeService(ExchangeVersion.Exchange2010_SP1);
        hookToServer.UseDefaultCredentials = true;
        hookToServer.Url = new Uri("TheExchangeServer")

您可以通过使用自动发现获取用户设置，这是一项与使用 AutodiscoverUrl 方法的服务完全独立的服务。

您需要的设置名称是 AlternateMailboxes，这将提供您有权访问的所有“其他”邮箱的集合。然后，您可以添加用户的默认邮箱以获得完整列表。

在 c# 中：

using Microsoft.Exchange.WebServices.Autodiscover;  // from nuget package "Microsoft.Exchange.WebServices"

    internal List<string> GetAccessibleMailboxes()
    {
        AutodiscoverService autodiscoverService = new AutodiscoverService("outlook.office365.com");
        autodiscoverService.Credentials = networkCredential;
        var userSmtpAddress = networkCredential.UserName;

        GetUserSettingsResponse userresponse = autodiscoverService.GetUserSettings(
            userSmtpAddress,
            UserSettingName.AlternateMailboxes);

        var alternateMailboxCollection = (AlternateMailboxCollection)userresponse.Settings[UserSettingName.AlternateMailboxes];
        var smtpAddressList = alternateMailboxCollection.Entries.ToList().Select(a => a.SmtpAddress).ToList();

        smtpAddressList.Add(userSmtpAddress);

        return smtpAddressList;
    }

You can do this by Using Autodiscover to get user settings, this is a completely separate service to the one with the AutodiscoverUrl method.

The setting name you need is AlternateMailboxes, this will give a collection of all the 'other' mailboxes you have access to. You might then add the user's default mailbox to get a complete list.

In c#:

using Microsoft.Exchange.WebServices.Autodiscover;  // from nuget package "Microsoft.Exchange.WebServices"

    internal List<string> GetAccessibleMailboxes()
    {
        AutodiscoverService autodiscoverService = new AutodiscoverService("outlook.office365.com");
        autodiscoverService.Credentials = networkCredential;
        var userSmtpAddress = networkCredential.UserName;

        GetUserSettingsResponse userresponse = autodiscoverService.GetUserSettings(
            userSmtpAddress,
            UserSettingName.AlternateMailboxes);

        var alternateMailboxCollection = (AlternateMailboxCollection)userresponse.Settings[UserSettingName.AlternateMailboxes];
        var smtpAddressList = alternateMailboxCollection.Entries.ToList().Select(a => a.SmtpAddress).ToList();

        smtpAddressList.Add(userSmtpAddress);

        return smtpAddressList;
    }
