Microsoft is investigating an issue causing Outlook search not to display recent emails in desktop apps running on Windows 11 systems.

Microsoft 正在调查导致 Outlook 搜索在 Windows 11 系统上运行的桌面应用程序中不显示最近电子邮件的问题。

The problem affects POP, IMAP, and offline Exchange accounts because Outlook's search feature uses the local Windows Search service to index emails.

该问题会影响 POP、IMAP 和脱机 Exchange 帐户，因为 Outlook 的搜索功能使用本地 Windows 搜索服务来索引电子邮件。

Microsoft 365 and connected Exchange accounts are not impacted because they use Service Search, which is not affected by this issue.

不过，Microsoft 365 和连接的 Exchange 帐户不受影响，因为它们使用的是不受此问题影响的搜索服务。

"When searching in Outlook Desktop on Windows 11 you might not see the most recent emails in the search results," Microsoft explains.

“在 Windows 11 上的 Outlook 桌面中搜索时，您可能不会在搜索结果中看到最新的电子邮件，”微软解释道。

"If you check Windows Indexing Options in the Control Panel, the indexing might be running slow or might be paused."

“如果您在控制面板中检查 Windows 索引选项，索引可能运行缓慢或可能已暂停。”

The company is currently working on addressing this known issue and shared a temporary fix for affected customers until a solution is available.

目前微软正在努力解决这个已知问题，并为受影响的客户共享一个临时修复程序，直到有可用的解决方案为止。

Microsoft advises Windows 11 users to mitigate the Outlook search bug by disabling Windows Desktop Search and switching to Outlook's built-in search engine as a workaround.

Microsoft 建议 Windows 11 用户通过禁用 Windows 桌面搜索并切换到 Outlook 的内置搜索引擎作为缓解 Outlook 搜索错误的解决方法。

To disable the Windows Desktop Search Service for Outlook, you must add a new PreventIndexingOutlook registry key using the steps outlined here.

要禁用 Outlook 的 Windows 桌面搜索服务，您必须使用此处概述的步骤添加新的 PreventIndexingOutlook 注册表项，如下图所示：

This is the second time Microsoft warned Outlook users of email search issues on systems running Windows 11.

这是微软第二次警告 Outlook 用户在运行 Windows 11 的系统上存在电子邮件搜索问题了。

As BleepingComputer reported in December, Outlook users also reported experiencing search issues last year in Outlook for Microsoft 365, Outlook 2019, and Outlook 2016 after upgrading to Windows 11.

正如 BleepingComputer在 12 月报道的那样，Outlook 用户还报告说，去年升级到 Windows 11 后，Outlook for Microsoft 365、Outlook 2019 和 Outlook 2016 中都遇到了搜索问题。

As those affected said, Outlook no longer showed results when searching for specific emails on IMAP/POP accounts, in some cases causing the app to freeze completely.

正如受影响的人所说，在 IMAP/POP 帐户上搜索特定电子邮件时，Outlook 不再显示结果，在某些情况下会甚至导致应用程序完全失去响应。

Those problems started showing up in June 2021, right after the first Windows 11 preview builds surfaced, impacting emails and other items stored locally by POP and IMAP accounts in PST or OST files.

这些问题在2021年6月，第一个 Windows 11 预览版本浮出水面之后就已经出现，影响了 POP 和 IMAP 帐户在 PST 或 OST 文件中本地存储的电子邮件和其他项目。

As mitigation, Microsoft also recommended users at the time to switch to Outlook's built-in search engine, which would remove the cause of the issue: Windows Desktop Search being broken after the search index got deleted during Windows 11 upgrades.

作为缓解措施，微软当时还建议用户切换到 Outlook 的内置搜索引擎，这将排查出造成问题的原因：在Windows 11 升级期间搜索索引被删除后，Windows 桌面搜索被破坏。

In January, Redmond also addressed Outlook search issues triggered after installing Windows 10 security updates released in November 2021 and later.

1 月，Redmond还解决了安装 2021 年 11 月及之后发布的 Windows 10 安全更新后触发的Outlook 搜索问题。

一切的输入都是有害的，一切的请求都是不可信的。
