Gmail无法正常工作的问题可能会以多种形式出现。有时，Gmail 应用^{(Gmail app)}不会将电子邮件发送到您的收件箱。其他时候，您的Gmail 收件箱^{(Gmail inbox)}反复无法在您的网络浏览器^{(web browser)}中加载。电子邮件通知问题在^{(Email notification)}Gmail中也很常见。

本文介绍了针对移动设备（Android 和 iOS^{(Android and iOS)}）和台式计算机上的几个Gmail问题的故障排除修复。^(Gmail)

1. 您的互联网连接^{(Internet Connection)} 正常^(Working)吗？

如果您的互联网连接出现问题，您的设备不会丢失Gmail 应用或收件箱。^{(Gmail app or inbox)}如果您在网络浏览器中访问^{(web browser)}Gmail ，请在新标签页中打开其他网站并确保它们正确加载。

在您的智能手机或平板电脑^{(smartphone or tablet)}上执行相同的操作。或者，在您的设备上打开其他依赖互联网的应用程序并检查它们是否正常工作。如果问题在所有应用程序或网页^{(apps or web pages)}中持续存在，则您的互联网连接^{(internet connection)}可能是罪魁祸首。

如果您使用的是移动数据或蜂窝数据，请确保您拥有有效的数据计划^{(data plan)}。让您的手机进入和退出飞行模式^{(airplane mode)}也有助于刷新您的互联网连接。

要对 Wi-Fi 连接进行故障排除^{(troubleshoot a Wi-Fi connection)}，请将您的设备移近^{(device closer)}路由器，更新路由器的固件，或者如果您仍然无法访问互联网，请重新启动路由器。同样^(Likewise)，检查网络的管理仪表板并确认您的设备^{(device isn)}未列入黑名单。

有关更多故障排除解决方案，请参阅我们关于修复慢速移动数据连接和通过 Wi-Fi 获得高速互联网的教程。^{(getting high-speed internet over Wi-Fi)}

2.检查Gmail服务状态

如果您的互联网连接不是Gmail无法正常工作的问题，请检查Gmail服务器是否出现临时停机或中断^{(downtime or outage)}。前往Google Workspace 状态信息中心^{(Google Workspace Status Dashboard)}并确认Gmail可用。 

Gmail旁边的绿色复选标记^{(green checkmark)}表示电子邮件服务^{(email service)}可用且运行顺利。黄色感叹号^{(yellow exclamation)}或红色“ X”图标^{(red “X” icon)}分别表示Gmail由于服务中断或服务中断^{(disruption or service outage)}而停机。

您还可以在DownDetector^{(DownDetector)}等网站监控平台上检查服务中断^{(service disruption)}。前往DownDetector 上的 Gmail 状态页面^{(Gmail’s status page on DownDetector)}，检查是否报告了任何Gmail问题。

3. 使用支持的浏览器

Gmail可能无法在未针对电子邮件服务^{(email service)}进行优化的网络浏览器上正常运行。为获得最佳用户体验，Google建议在最新版本的Google Chrome、Mozilla Firefox、Safari或Microsoft Edge上访问^{(Microsoft Edge)}Gmail。

此外，您必须在所使用的任何浏览器上启用cookie 和Javascript 。否则^(Otherwise)，Gmail可能无法加载，并且您可能无法使用某些Gmail功能。上述推荐的浏览器默认启用cookie 和Javascript 。因此，除非您之前禁用了 cookie 或Javascript，否则您不必手动打开它们。

如果Gmail仍然无法在您的浏览器中运行，请关闭并重新打开浏览器，然后重试。您还应该确保浏览器是最新的。

4. 在隐身模式下试用 Gmail

有缺陷的浏览器^{(Buggy browser)}扩展程序或加载项可能会干扰某些Gmail功能并阻止电子邮件服务正常工作。以隐身模式访问Gmail有助于诊断问题是否由有害扩展程序或应用程序引起。

隐身模式（或隐私浏览^{(Private Browsing)}）禁用所有浏览器扩展，防止任何不良扩展影响Gmail 性能^{(Gmail performance)}。如果Gmail和其他网站在隐身模式下正常工作，请一次禁用一个浏览器扩展程序以检测有问题的扩展程序或插件^{(extension or add-on)}。

我们建议阅读有关仅安装安全浏览器扩展^{(installing only safe browser extensions)}的指南，以了解有关低风险、中风险和高风险浏览器扩展的更多信息。

5.调整日期和时间设置

如果日期或时间^{(date or time)}不正确，您的设备可能无法与 Gmail 服务器建立连接。前往设备的设置菜单，确保日期和时间设置^{(date and time settings)}设置为自动更新。

6. 在 Gmail 中启用 IMAP

IMAP（互联网消息访问协议^{(Internet Message Access Protocol)}）是一个电子邮件程序，可让您从其他电子邮件客户端/应用程序访问您的Gmail 收件箱。^{(Gmail inbox)}如果您没有在Apple Mail、Yahoo Mail、Outlook或其他使用IMAP访问Gmail的应用程序中收到^(Gmail)Gmail邮件，请检查您的Gmail 帐户^{(Gmail account)}设置中是否启用了IMAP 。

1. 在网络浏览器^{(web browser)}中打开您的Gmail 收件箱^{(Gmail inbox)}，选择齿轮图标^{(gear icon)}，然后选择查看所有设置^{(See all settings)}。

1. 转到Forwarding and POP/IMAP选项卡，滚动到“IMAP 访问”部分^{(” section)}，然后选择启用 IMAP^{(Enabled IMAP)}。

1. 选择页面底部的保存更改按钮。^{(Save Changes)}

7. 检查Gmail 通知设置^{(Gmail Notification Settings)}

如果Gmail不会在您的设备上发送新电子邮件通知，请检查您的帐户设置并选择您希望收到通知的电子邮件类型。同样^(Likewise)，确保在系统级别启用^{(system level)}Gmail 通知^{(Gmail notification)}。

What to Do If Gmail Is Not Working? 11 Quick Fixes

Issues with Gmail not working can play out in many forms. Sometimes, the Gmail app won’t deliver emails to your inbox. Other times, your Gmail inbox repeatedly fails to load in your web browser. Email notification problems are also quite common with Gmail.

This article covers troubleshooting fixes for several Gmail issues on mobile devices (Android and iOS) and desktop computers.

1. Is Your Internet Connection Working?

Your device won’t lose the Gmail app or inbox if there’s a problem with your internet connection. If you’re accessing Gmail in a web browser, open other websites in a new tab and ensure they load correctly.

Do the same on your smartphone or tablet. Alternatively, open other internet-dependent apps on your device and check if they work without issues. If the problem is persistent across all apps or web pages, your internet connection likely is the culprit.

If you’re using mobile or cellular data, make sure you have an active data plan. Putting your phone in and out of airplane mode could also help refresh your internet connection.

To troubleshoot a Wi-Fi connection, move your device closer to the router, update the router’s firmware, or reboot the router if you still can’t access the internet. Likewise, inspect the network’s admin dashboard and confirm that your device isn’t blacklisted.

Refer to our tutorials on fixing slow mobile data connections and getting high-speed internet over Wi-Fi for more troubleshooting solutions.

2. Check Gmail Service Status

If your internet connection isn’t the problem with Gmail not working, check that the Gmail servers aren’t experiencing a temporary downtime or outage. Head to the Google Workspace Status Dashboard and confirm that Gmail is available. 

A green checkmark next to Gmail means the email service is available and working smoothly. A yellow exclamation or red “X” icon indicates that Gmail is down due to service disruption or service outage, respectively.

You can also check for service disruption on website monitoring platforms like DownDetector. Head to Gmail’s status page on DownDetector and check if any Gmail problems are reported.

3. Use a Supported Browser

Gmail may not work correctly on web browsers that aren’t optimized for the email service. For optimum user experience, Google recommends accessing Gmail on the latest versions of Google Chrome, Mozilla Firefox, Safari, or Microsoft Edge.

Additionally, you must have cookies and Javascript enabled on whatever browser you’re using. Otherwise, Gmail may not load, and you may be unable to use some Gmail features. The recommended browsers mentioned above have both cookies and Javascript enabled by default. So, unless you previously disabled cookies or Javascript, you don’t have to turn them on manually.

If Gmail still isn’t working in your browser, close and reopen the browser and try again. You should also ensure the browser is up-to-date.

4. Try Gmail in Incognito Mode

Buggy browser extensions or add-ons can interfere with some Gmail functionalities and prevent the email service from working correctly. Accessing Gmail in incognito mode can help diagnose if the problem is caused by harmful extensions or applications.

Incognito Mode (or Private Browsing) disables all browser extensions, preventing any bad extension from affecting Gmail performance. If Gmail and other websites work correctly in incognito mode, disable your browser extensions one at a time to detect the problematic extension or add-on.

We recommend reading this guide on installing only safe browser extensions to learn more about low, medium, and high-risk browser extensions.

5. Adjust Date and Time Settings

Your device might be unable to establish a connection with Gmail’s servers if its date or time is incorrect. Head to your device’s settings menu and ensure the date and time settings are set to update automatically.

In Android, go to Settings > System > Date & time and toggle on both Use network-provided time and Use network-provided time zone.

To update your iPhone and iPad’s date & time, go to Settings > General > Date & Time and toggle on Set Automatically.

6. Enable IMAP in Gmail

IMAP (Internet Message Access Protocol) is an email program that lets you access your Gmail inbox from other email clients/apps. If you aren’t getting Gmail messages in the Apple Mail, Yahoo Mail, Outlook, or other apps that use IMAP to access Gmail, check that IMAP is enabled in your Gmail account settings.

1. Open your Gmail inbox in a web browser, select the gear icon, and select See all settings.

1. Go to the Forwarding and POP/IMAP tab, scroll to the “IMAP access” section, and choose Enabled IMAP.

1. Select the Save Changes button at the bottom of the page.

7. Check Gmail Notification Settings

If Gmail won’t deliver notifications for new emails on your device, check your account settings and select the type of emails you want to be notified about. Likewise, make sure Gmail notification is enabled at the system level.

Change Gmail Notification Settings in Android

Open the Gmail app on your device and follow the steps to check and change email notification settings.

1. Tap the hamburger menu icon in the top-left corner and select Settings.
2. Select the account whose notification settings you want to change.

1. Select Notifications in the “Notifications” section and tap All.

1. Return to the “Notifications” section, tap Manage notifications, toggle on Show notifications, and select the Alerting notification delivery.

Change Gmail Notification Settings in iOS

First, you need to ensure Gmail notification is allowed in your iPhone’s Settings menu. Afterward, open the Gmail app and configure your inbox notification preferences.

1. Go to Settings, select Gmail, select Notifications, and toggle on Allow Notifications.

Make sure you also toggle on Sounds, Badges, Lock Screen, Notification Center, and Banners in the “Alerts” section.

1. Open Gmail, tap the hamburger menu icon in the top-left corner, and select Settings.
2. Select the email account whose notification settings you want to change.

1. Scroll to the “Notifications” section and select the type of emails you want to be notified about.

The All new mail option will send notifications for all new emails in your inbox, while “Primary only” will only notify you about new emails in the Primary section of your inbox. Select High priority only if you want notifications for emails that Gmail identifies as high priority.

Change Gmail Notification Settings on Web

Open your Gmail inbox on a web browser and follow the steps below.

1. Select the gear icon next to the search bar, and select See all settings.

1. In the General tab, scroll to the “Desktop notifications” section, and select Click here to enable desktop notifications for Gmail.

1. Select Allow on the “Show notifications” prompt that pops up below the address bar.

1. Next, choose either New mail notifications on or Important mail notifications on and then select a preferred notification alert in the Mail notification sounds drop-down menu.

8. Force Close and Reopen Gmail

Force closing Gmail on your mobile device can resolve temporary system glitches causing the app to freeze, crash, or go unresponsive.

Force Close Gmail on iPhone or iPad

The steps to force close an app depend on the model of your iPhone or iPad.

1. Open the iOS or iPadOS App Switcher—swipe up from the bottom to the middle of your device’s screen.

If your iPhone or iPad has a Home button, double-click the button to open the App Switcher.

1. Locate Gmail and swipe up on the app preview. That’ll force-close Gmail on your iPhone or iPad.

1. Head to your device’s Home Screen or App Library, reopen Gmail and check if it now works as expected.

Force Close Gmail in Android

Follow the steps below to force-close Gmail on an Android device.

1. Go to your device’s Home Screen or app launcher, press and hold the Gmail app icon, and select the info icon.

Alternatively, open the Settings app, go to App & notifications > See All Apps (or App info), and select Gmail.

1. Tap Force Stop, select OK on the confirmation prompt and tap Open to relaunch Gmail.

If the problem persists, clear the app’s cache file and storage data and try again. Jump to the next section for detailed instructions.

9. Clear Gmail Cache & App Data

Accumulation of corrupt cache files and app data could cause the Gmail app to crash and exhibit other forms of malfunction.

Force close Gmail and follow the steps below to clear the app’s cache and storage data.

1. Go to Settings > Apps & notifications > See All Apps (or App info) > Gmail and select Storage & cache.
2. Tap the Clear Cache option.

Open Gmail and check if it now works correctly. Otherwise, delete Gmail’s data from your device if clearing its cache storage doesn’t resolve the problem.

1. Tap Clear Storage (or Clear Data) and select OK on the confirmation prompt.

Note that you’ll have to re-do all customizations made to Gmail (e.g., notification settings, theme, swipe actions, etc.) after clearing the app’s data.

10. Update Gmail

Software bugs or device incompatibility are noteworthy causes for failure. You might encounter issues using Gmail if the app version installed on your device is outdated or incompatible with your device.

Head to your device’s app store (Google Play Store or Apple App Store) and update Gmail to the latest version. If the problem continues, uninstall and reinstall Gmail from your device. That could also help resolve minor performance issues.

11. Restart Your Device

Do you have the latest Gmail version on your device? Does Gmail still fail to work correctly after updating the app? Rebooting your device could fix the problem. Shut down your device, turn it back on, and try using Gmail again.
