当您在Windows 计算机上打开应用程序时， (Windows computer)Microsoft Outlook是否会间歇性崩溃？应用程序是否偶尔会冻结并随机显示“ Microsoft Outlook无响应”警报？
在本教程中，您将了解Microsoft Outlook 无法在Windows中响应(Microsoft Outlook fails to respond)的原因以及该问题的八个潜在修复程序。
1.强制关闭并重新打开 Outlook
在Windows 任务管理器(Windows Task Manager)中终止Outlook可能会使事情恢复正常。
- 右键单击开始菜单图标(Start menu icon)或按Windows 键(Windows key)+ X ，然后在快速访问菜单中选择任务管理器。(Task Manager)
快速提示：(Quick Tip:) Ctrl +(Ctrl) Shift +(Shift) Esc键盘(Esc) 快捷键(keyboard shortcut)是启动Windows 任务管理器(Windows Task Manager)的更快方法。
- 转到“进程”选项卡，选择Microsoft Outlook，然后选择右下角的结束任务。(End task)
如果在“进程”选项卡中没有找到 Outlook，请转到“详细信息”选项卡，选择OUTLOOK.EXE，然后选择结束任务(End task)。
- 在确认提示中选择结束进程。(End process)
重新打开 Microsoft Outlook(Reopen Microsoft Outlook)并检查应用程序是否可以正常工作而不会冻结或崩溃。
2. 在安全模式下运行 Outlook
如前所述，如果某些预安装或第三方加载项影响其性能， Microsoft Outlook可能不会响应。(Microsoft Outlook)启动应用程序时，以安全模式启动 Outlook(Starting Outlook in Safe Mode)将禁用所有加载项和其他自定义项。这将帮助您确定损坏或冲突的加载项是否是Outlook(Outlook isn)没有响应的原因。
- 按Windows 键(Windows key)+ R打开运行框。
- 在对话框中键入或粘贴Outlook.exe /safeOK或按Enter。
如果Windows无法通过“运行”框(Run box)以安全模式启动(Safe Mode)Outlook，请改用键盘快捷键(keyboard shortcut)。按住(Press)Ctrl 键(Ctrl key)并选择桌面(Desktop)、任务栏(Taskbar)或开始菜单上的(Start menu)Outlook 应用程序(Outlook app)图标。
- 系统会提示您确认是否要以安全模式打开Outlook。选择是(Yes)继续。
- 在“配置文件名称”下拉菜单(menu and select)中选择Outlook ，然后选择“(Outlook)确定(OK)” 。
如果Outlook在安全模式下正常工作，则表明加载项对“ Microsoft Outlook (Not Responding) ”错误(” error)负责。接下来要做的是禁用所有加载项并重新启动Outlook。
- 在菜单栏上选择文件。(File)
- 选择左侧边栏底部的选项(Options)（或更多(More)>选项）。(Options)
- 进入加载项(Add-ins)页面，在“管理”下拉菜单中选择COM加载项，然后选择(COM Add-ins)Go。
- 取消选中“可用插件(Add-ins)”部分中的所有插件，然后选择“(section and select) 确定(OK)” 。
关闭(Close)并重新打开Outlook，依次重新启用禁用的加载项，以确定导致Outlook崩溃的坏/损坏的加载项。
- 返回 Outlook 的加载项页面(Add-ins page)（参见步骤 #7），检查要启用的加载项，然后选择OK。
关闭(Close)并重新打开Outlook，然后对列表中的所有内置或第三方加载项重复步骤 #8。如果Outlook在启用加载项后冻结并显示“ Microsoft Outlook未响应”警报(” alert)，则说明问题的根源。在安全模式下重新打开 Outlook(Reopen Outlook)，禁用加载项，然后再次启动Outlook。
3.更新Outlook
如果您的 PC 上安装的版本已过时或存在错误， Outlook(Outlook)有时可能会在您的 PC 上无响应。将您的计算机连接到互联网并按照以下步骤操作：
- 打开 Outlook 并选择菜单栏上的文件。(File)
- 选择侧边栏上的Office 帐户(Office Account)。
- 选择更新选项(Update Options)下拉按钮。
- 选择立即更新(Update Now)。
这将启动Microsoft Office 即点即用客户端(Microsoft Office Click-to-Run Client)。如果有新版本的应用程序，该工具将更新Outlook 。否则，它会显示“你是最新的！”(” alert)如果您的 PC 上安装了最新的Outlook 版本，则会发出警报。(Outlook version)
如果“ Microsoft Outlook无响应”问题仍然存在，请关闭更新客户端并尝试下一个故障排除解决方案。(troubleshooting solution)
4. 运行Outlook 高级诊断工具(Outlook Advanced Diagnostics Tool)
Microsoft有一个自动诊断工具，可以修复Outlook和其他Office 或 Windows 应用程序(Office or Windows applications)的问题。下载安装文件(setup file)，在您的 PC 上安装该工具，然后按照以下步骤操作。还有一件事：确保您的 PC 已连接到互联网。
- 打开开始菜单，在搜索栏中输入(search bar)microsoft support ，在“Microsoft Support and Recovery Assistant”菜单中打开选择Run as administrator 。
- 选择Outlook，然后选择下一步(Next)。
- 选择最能描述PC 上Outlook问题的问题 - (Outlook)Outlook 无法启动(Outlook won’t start)、Outlook 停止响应或冻结(Outlook stops responding or freezes)，或者Outlook 不断崩溃并显示“Microsoft Outlook 已停止工作”消息(Outlook keeps crashing with a message ‘Microsoft Outlook has stopped working”)。选择下一步(Next)继续。
- 如果您在受影响的计算机上运行诊断工具，请选择是(Yes)并选择下一步。(Next)
- 选择您的Microsoft 帐户或选择(Microsoft account or select) 使用其他帐户(Use another account)以使用其他帐户登录。
等待(Wait)该工具在您的计算机上诊断Outlook并遵循建议。如果 Microsoft 支持和恢复助手无法解决问题，请尝试以下其他故障排除步骤。
5. 减少 Outlook 的数据文件
随着您发送和接收更多电子邮件，您的Outlook 收件箱(Outlook inbox)（和数据）会变得更大。如果 Outlook 的数据文件损坏(data file becomes corrupt)或太大， Outlook将需要更长时间打开电子邮件并执行其他任务。Outlook 甚至可能在使用过程中崩溃或偶尔无法响应。
有趣的是，微软(Microsoft)允许用户手动压缩或减小Outlook数据文件的大小，而无需删除邮件和文件夹。
- 打开 Outlook，选择菜单栏上的文件，选择帐户(File)设置(Account Settings)下拉选项，然后选择帐户设置(Account Settings)。
- 转到Data Files选项卡，选择要减少/压缩的数据文件，然后选择(data file)Settings。
- 前往Advanced选项卡并选择Outlook Data File Settings。
- 选择立即压缩(Compact Now)并在Outlook完成数据文件(data file)压缩后选择确定(OK)。
关闭(Close)并重新打开Outlook并监视应用程序的性能。如果这不能修复“ Microsoft Outlook无响应”故障，请修复Outlook 应用程序。(Outlook app)
6.修复Outlook
修复Outlook可能会解决导致应用程序在您的收件箱中发送或阅读电子邮件时出现故障的问题。(sending or reading emails)您可以从Windows 设置应用程序(Windows Settings app)或通过控制面板(Control Panel)修复Outlook。
转到设置(Settings)>应用程序(Apps)>应用程序和功能，选择(Apps & features)Microsoft Outlook旁边的菜单图标，然后选择修改(Modify)。
要从控制面板(Control Panel)修复Outlook，请打开Control Panel >程序(Programs)>程序和功能(Programs and Features)，选择Microsoft Outlook，然后选择菜单栏上的更改。(Change)
选择您要如何修复Outlook，然后选择修复(Repair)。

(Online repair)另一方面，在线修复会从您的 PC 中卸载 Outlook，并从Microsoft服务器重新安装一个新副本。该操作需要互联网连接。另外，完成也需要更长的时间。
我们建议先运行快速修复(Quick Repair)。如果问题仍然存在，请重新打开修复工具(repair tool)并选择“在线修复(Online Repair)”选项。
7.重启你的电脑
这样做将刷新Windows ，关闭与(Windows)Outlook冲突的程序，并修复导致Outlook出现故障的其他问题。确保在重新启动 PC 之前关闭所有应用程序，以免丢失任何未保存的工作。
按(Press)Windows 键或开始(Windows key or Start)菜单图标，选择电源图标(Power icon)，然后选择重新启动(Restart)。
8. 更新你的电脑
Windows更新有时会附带Microsoft Outlook和其他Office 应用程序(Office apps)的更新。这些更新修复了阻止Outlook在Windows中正确打开或运行的问题。
如果您有一台Windows 11计算机，请打开“设置”(Settings)应用，在边栏上选择“ Windows 更新(Windows Updates)”，然后安装或恢复任何可用的更新。
要在Windows 10中安装Windows 更新(Windows Updates)，请转到设置(Settings)>更新和安全(Update & Security)> Windows 更新(Windows Update)，然后选择检查更新(Check for updates)。

Microsoft Outlook Not Responding? 8 Fixes to Try
Is Microsoft Outlook crashing intermittently when you open the app on your Windows computer? Does the app occasionally freeze and display a “Microsoft Outlook Not Responding” alert at random intervals?
In this tutorial, you’ll learn why Microsoft Outlook fails to respond in Windows and eight potential fixes to the problem.
1. Force Close and Reopen Outlook
Terminating Outlook in the Windows Task Manager might set things back in order.
- Right-click the Start menu icon or press Windows key + X, and select Task Manager in the Quick Access menu.
Quick Tip: The Ctrl + Shift + Esc keyboard shortcut is a faster way to launch the Windows Task Manager.
- Go to the “Processes” tab, select Microsoft Outlook, and select End task in the bottom-right corner.
If you don’t find Outlook in the “Processes” tab, go to the “Details” tab, select OUTLOOK.EXE, and select End task.
- Select End process on the confirmation prompt.
Reopen Microsoft Outlook and check if the app works without freezing or crashing.
2. Run Outlook in Safe Mode
As mentioned earlier, Microsoft Outlook may not respond if some pre-installed or third-party add-ins are affecting its performance. Starting Outlook in Safe Mode will disable all add-ins and other customizations when you launch the app. That’ll help you determine if a broken or conflicting add-in is the reason why Outlook isn’t responding.
- Press the Windows key + R to open the Run box.
- Type or paste Outlook.exe /safe in the dialog box and select OK or press Enter.
If Windows fails to launch Outlook in Safe Mode via the Run box, use the keyboard shortcut instead. Press and hold the Ctrl key and select the Outlook app icon on the Desktop, Taskbar, or Start menu.
- You’ll get a prompt asking you to confirm that you want to open Outlook in safe mode. Select Yes to proceed.
- Choose Outlook in the “Profile Name” drop-down menu and select OK.
If Outlook works properly in safe mode, that tells you an add-in is responsible for the “Microsoft Outlook (Not Responding)” error. The next thing to do is to disable all add-ins and restart Outlook.
- Select File on the menu bar.
- Select Options (or More > Options) at the bottom of the left sidebar.
- Go to the Add-ins page, select COM Add-ins in the “Manage” drop-down menu, and select Go.
- Uncheck all add-ins in the “Add-ins available” section and select OK.
Close and reopen Outlook, re-enable the disabled add-ins one after another to determine the bad/broken add-in responsible for crashing Outlook.
- Return to Outlook’s Add-ins page (see step #7), and check the add-in you want to enable, and select OK.
Close and reopen Outlook and repeat step #8 for all built-in or third-party add-ins on the list. If Outlook freezes and displays the “Microsoft Outlook Not Responding” alert after enabling an add-in, that tells you the source of the problem. Reopen Outlook in safe mode, disable the add-in, and launch Outlook again.
3. Update Outlook
Outlook may occasionally go unresponsive on your PC if the version installed on your PC is outdated or bug-ridden. Connect your computer to the internet and follow these steps:
- Open Outlook and select File on the menu bar.
- Select Office Account on the sidebar.
- Select the Update Options drop-down button.
- Select Update Now.
That’ll launch the Microsoft Office Click-to-Run Client. The tool will update Outlook if there’s a new version of the app. Otherwise, it’ll display a “You’re up to date!” alert if you have the latest Outlook version installed on your PC.
Close the update client and try the next troubleshooting solution if the “Microsoft Outlook Not Responding” issue persists.
4. Run the Outlook Advanced Diagnostics Tool
Microsoft has an automated diagnostics tool that fixes issues with Outlook and other Office or Windows applications. Download the setup file, install the tool on your PC, and follow the steps below. One more thing: make sure your PC is connected to the internet.
- Open the Start menu, type microsoft support in the search bar, and open select Run as administrator in the “Microsoft Support and Recovery Assistant” menu.
- Select Outlook and select Next.
- Select the problems that best describe the issue with Outlook on your PC—Outlook won’t start, Outlook stops responding or freezes, or Outlook keeps crashing with a message ‘Microsoft Outlook has stopped working”. Select Next to proceed.
- Choose Yes and select Next if you’re running the diagnostics tool on the affected computer.
- Select your Microsoft account or select Use another account to sign in with a different account.
Wait for the tool to diagnose Outlook on your computer and follow the recommendations. Try other troubleshooting steps below if Microsoft Support and Recovery Assistant don’t fix the problem.
5. Reduce Outlook’s Data File
Your Outlook inbox (and data) grows bigger as you send and receive more emails. Outlook will take longer open emails and execute other tasks if its data file becomes corrupt or too large. Outlook may even crash or occasionally fail to respond during usage.
Interestingly, Microsoft lets users manually compact or reduce the size of the Outlook data file without having to delete messages and folders.
- Open Outlook, select File on the menu bar, select the Account Settings drop-down option, and select Account Settings.
- Go to the Data Files tab, select a data file you want to reduce/compress, and select Settings.
- Head to the Advanced tab and select Outlook Data File Settings.
- Select Compact Now and select OK when Outlook is done compressing the data file.
Close and reopen Outlook and monitor the app’s performance. Repair the Outlook app if this doesn’t fix the “Microsoft Outlook Not Responding” glitch.
6. Repair Outlook
Repairing Outlook may resolve issues causing the app to malfunction when sending or reading emails in your inbox. You can repair Outlook from the Windows Settings app or via the Control Panel.
Go to Settings > Apps > Apps & features, select the menu icon next to Microsoft Outlook, and select Modify.
To repair Outlook from the Control Panel, open the Control Panel > Programs > Programs and Features, select Microsoft Outlook, and select Change on the menu bar.
Choose how you want to repair Outlook and select Repair.
Quick Repair is a self-repair process that scans for file corruption and replaces any damaged file with fresh copies available locally on your computer. It’s fast and requires no internet connection.
Online repair, on the other hand, uninstalls Outlook from your PC and reinstalls a fresh copy from Microsoft servers. The operation requires an internet connection. Plus, it also takes a longer time to reach completion.
We recommend running a Quick Repair first. If the problem persists, re-open the repair tool and select the Online Repair option instead.
7. Restart Your Computer
Doing this will refresh Windows, close programs conflicting with Outlook, and fix other issues causing Outlook to malfunction. Make sure you close all apps before restarting your PC, so you don’t lose any unsaved work.
Press the Windows key or Start menu icon, select the Power icon, and select Restart.
8. Update Your Computer
Windows Updates sometimes ship with updates for Microsoft Outlook and other Office apps. These updates fix issues that prevent Outlook from opening or running correctly in Windows.
If you have a Windows 11 computer, open the Settings app, select Windows Updates on the sidebar, and install or resume any available update.
To install Windows Updates in Windows 10, go to Settings > Update & Security > Windows Update and select Check for updates.
Stabilize Outlook in Windows
Some reports suggest that third-party antivirus software can interfere with Outlook’s performance in Windows. If Outlook still crashes after trying these fixes, disable or uninstall your antivirus tool. Contact Microsoft Office Support if the problem persists.
