[英]Outlook 2016 Interop/C#: How to programmatically get around “Click here to view more on Microsoft Exchange”

原文 2017-03-14 15:52:10 5 1 c#/ outlook

I have a program that needs to access all the emails in a users mailbox. 我有一个程序需要访问用户邮箱中的所有电子邮件。 However, unless the "Click here to view more..." link at the bottom of each mailbox is clicked, some messages will be skipped. 但是，除非单击每个邮箱底部的“单击此处查看更多...”链接，否则将跳过某些消息。 Is there a way around this? 有没有解决的办法？ I'm using C# and Outlook.Interop. 我正在使用C＃和Outlook.Interop。 Thanks in advance. 提前致谢。

Use Extended MAPI (C++ or Delphi only) or Redemption (any language) to open the folder in the online mode using the MAPI_NO_CACHE flag. 使用扩展MAPI（仅C ++或Delphi）或兑换（任何语言）使用MAPI_NO_CACHE标志以在线模式打开文件夹。 You can play with that flag in OutlookSpy - click IMAPIFolder button, select the PR_ENTRYID property, right click, select IMAPISesion::OpenEntry , make sure MAPI_NO_CACHE bit is checked. 您可以在OutlookSpy中使用该标志-单击IMAPIFolder按钮，选择PR_ENTRYID属性，右键单击，选择IMAPISesion::OpenEntry ，确保已选中MAPI_NO_CACHE位。 When using Redemption, call RDOSession . 使用兑换时，请调用RDOSession 。 GetFolderFromID() and specify the MAPI_NO_CACHE flag.
