对于使用 javamail 处理的一个 Office365 邮箱,folder.close(true) 不会清除已删除的



使用 JavaMail 在 Office365 上托管多个邮箱进行处理。IMAP 协议用于访问这些邮箱。

处理来自邮箱的邮件后,使用以下2种方法删除邮件

  1. message.setFlag(Flags.Flag.Deleted, true ); - set 是删除标志。
  2. folder.close(true)- 此命令清除删除标志设置为 true 的邮件。

上述 2 个命令在所有邮箱上工作超过 3 个月,但几天后 - folder.close(true) 停止对其中一个邮箱工作。

标记为已删除的邮件不会为邮箱清除,也不会显示在 Office 365 的 Web Outlook 中。从网络展望中手动删除工作正常。

但是现在,处理过的电子邮件正在收件箱中累积,因为它们没有被删除(清除)。

其他邮箱使用上述方法工作正常。这个邮箱在3 +个月内也工作正常,但自最近几天以来出现了这个问题。

问题特定于 Office 365 邮箱配置。这是两件事的组合:

  1. 邮箱的保留策略是无限期的。
  2. 未为邮箱启用存档。

从邮箱中删除电子邮件后,它们将转到"可恢复的项目"文件夹。一旦邮箱配额超过允许的最大大小,由于邮箱的保留策略是无限期的,因此不会从此文件夹中删除它们。因此,收件箱中的任何删除都不会进入"可恢复的项目"文件夹,因为它已满,并且这些邮件再次放入邮箱中。

解决方案是开始存档邮箱,仅保留最近 7 天的可恢复项目。
