Microsoft Office 应用程序^{(Microsoft Office applications)}可以自动将文件保存到您的 OneDrive 云帐户。但是，您的 OneDrive 帐户或 OneDrive 的同步设置出现问题会在Office应用程序 中触发“上传被阻止^{(Upload Blocked)}”错误。

本教程介绍了Windows计算机上Office应用程序中OneDrive Upload Blocked错误的可能解决方案。以下故障排除解决方案适用于所有Office应用程序——Microsoft Word、Excel、Powerpoint、Outlook等。

1. 重新连接您的 OneDrive 帐户

Microsoft认为将您的Microsoft帐户重新连接到Office应用程序将修复OneDrive同步错误。将您的计算机连接到 Internet，打开受影响的Office应用程序，然后按照以下步骤操作。

1. 在Office^(Office)应用 中打开“文件^(File)”选项卡。

1. ^{(Select Office Account)}选择侧栏上的Office 帐户，然后选择活动OneDrive或用户帐户 旁边的删除。^(Remove)

1. 在弹出窗口中选择是。

1. 打开添加^(Add)服务下拉菜单以将您的 OneDrive 帐户重新连接到应用程序。

1. 选择存储，然后选择OneDrive。如果您使用“Microsoft 365 for Business”帐户，请^{(“Microsoft 365 for Business” account)}选择 OneDrive^{(Select OneDrive)} for Business。

输入您的Microsoft帐户电子邮件和密码以继续。尝试再次将文档保存到OneDrive并检查重新连接您的帐户是否可以解决“上传被阻止”错误。

2. 恢复 OneDrive 同步

暂停 OneDrive 的同步可能会导致Microsoft Office应用程序抛出“上传被阻止”错误。检查 OneDrive 的设置并确保您的计算机正在将文件同步到云存储。

1. 右键单击^{(Right-click)}任务栏上的OneDrive图标- 查看^{(Taskbar—see)}PC 屏幕的右下角。如果屏幕上显示“您的文件当前未同步”消息，则会禁用 OneDrive同步。^(OneDrive)
2. 选择齿轮图标并选择恢复^(Resume)同步以重新启用 OneDrive 的同步。

当OneDrive^(OneDrive)显示“您的文件已同步”消息 时，请尝试再次保存文档。

3. 验证 OneDrive 的存储可用性^{(Storage Availability)}

^(Office)如果您用尽存储配额，Office应用程序将不会将文档保存或同步到 OneDrive。如果“上传被阻止”错误仍然存​​在，请检查您是否没有用完 OneDrive 存储空间。

1. 打开任务栏上的^(Taskbar)OneDrive菜单，选择齿轮图标，然后选择设置^(Settings)。

1. 前往“帐户^(Account)”选项卡并查看与您的帐户相关联的免费OneDrive存储空间。选择获取^{(Select Get)}更多存储空间以升级您的Microsoft 365帐户以获得更多OneDrive存储空间。

4.删除Office App的缓存^(Cache)文件

^(Corrupt)Office应用程序中^(Office)损坏的缓存文件可能会阻止将文档上传到OneDrive。删除受影响Office应用程序缓存系统中的文件可能会修复“上传被阻止”错误。

1. 打开Office应用程序的“文件^(File)”菜单，在侧边栏上选择“更多”，然后选择“选项”。

1. 打开保存^(Save)选项卡，滚动到“缓存设置”部分，然后选择删除^(Delete)缓存文件按钮。

1. ^{(Select Delete Cached Files)}在弹出窗口中 选择删除缓存文件，然后选择确定以保存更改。

5.重新打开Office应用

^(Force)如果重新连接 OneDrive 帐户后“上传被阻止”错误仍然存​​在，请强制关闭Office应用程序。^(Office)如果您尚未在本地（在您的计算机上）保存文档，我们建议您将内容粘贴到其他地方作为备份。假设^(Say)您在Microsoft Word中工作；将Word^(Word)文档的内容复制并粘贴到Google Docs中。

Press Ctrl + Shift + Esc打开Windows 任务管理器^{(Windows Task Manager)}。选择^(Select)或右键单击Office应用程序，然后选择结束^(End)任务。

重新打开该应用并检查它是否会将对您的文档所做的更改同步到OneDrive。

6.更新Office应用程序

Office更新附带新功能、安全补丁、错误修复和其他改进。Microsoft会频繁更新Office应用程序并自动在您的设备上安装更新。

“上传被阻止”错误可能是因为您使用的是旧版或过时的Office应用程序版本。将Office^(Office)应用配置为自动更新，或手动检查新更新。将您的计算机连接到 Internet，然后按照以下步骤将Office更新到最新版本。

打开受影响的Office应用程序并打开文件菜单中的帐户选项卡。^(Account)展开更新^(Update) 选项^(Options)菜单并选择立即更新^(Update)。

^{(Select Enable)}如果更新菜单中缺少“立即更新”，请 选择启用更新。

7.禁用Office上传缓存系统^{(Office Upload Cache System)}

在Windows中，OneDrive同步Office应用程序中的文件。这种集成有一些好处^{(integration has some benefits)}——它允许您与其他人共同编辑和处理共享文档。但是，如果OneDrive和Office上传缓存系统受到干扰，您可能会收到“上传被阻止”错误消息。

在 OneDrive 的设置中关闭Office上传可能会解决“上传被阻止”错误。

1. 选择任务栏通知区域中的白色或蓝色OneDrive（云）图标。如果通知区域中缺少图标，请展开显示^(Show)隐藏图标菜单并选择OneDrive图标。

1. 选择OneDrive^(OneDrive)菜单右上角的齿轮图标，然后选择设置^(Settings)。

1. 前往Office选项卡并取消选中使用 Office^{(Use Office)}应用程序同步我打开的Office文件。选择确定^{(Select OK)}以保存更改。

8.维修处

^{(Repair the Microsoft Office application)}如果上述故障排除修复都不能解决“上传被阻止”错误，请 修复 Microsoft Office 应用程序。

1. 按Windows键 + X 并在快速访问^{(Quick Access)}菜单 上选择安装^(Install)应用程序（或Windows 10中的应用程序^(Apps)和功能^(Features)） 。

1. 选择受影响的Office^(Office)应用旁边的菜单图标，然后选择修改^(Modify)。

1. 选择^(Select)快速修复^{(Quick Repair)}或在线修复^{(Online Repair)}，然后选择修复^(Repair)按钮。

“快速修复”是一种更快的修复选项，它只检测和修复导致Office应用出现故障的损坏文件。另一方面，“在线修复”提供全面的修复并修复每个可能的问题。^{(Online Repair)}请注意，“在线修复^{(Online Repair)}”需要互联网连接。

Microsoft建议仅当“快速修复”无法解决您尝试修复的问题时才运行“在线修复”。

1. 在确认提示中选择修复^{(Select Repair)}以开始操作。

1. 如果任何Office应用已打开，您将收到关闭该应用的提示。在继续之前将您的文档保存在应用程序中。选择继续^{(Select Continue)}授予修复工具关闭应用程序的权限。

该工具将修复您计算机上的所有Office程序和功能。

1. 修复操作完成后，关闭该工具并重新启动计算机。

9. 更新视窗

Windows操作系统中特定于 OneDrive 的错误可能会阻止Office应用程序将文档上传到云存储平台。

转到Settings > Windows Update，然后选择“检查^(Check)更新”或“立即重新启动^(Restart)” 。

在Windows 10中，前往Settings > Update和Security > Windows Updates并安装适用于您计算机的任何更新。

重新安装 Office

如果尝试这些修复后错误仍然存​​在，请 联系Microsoft 支持^{(Microsoft Support)}或卸载并重新安装Office应用程序。^(Office)

9 Ways to Fix OneDrive ”Upload Blocked” Errors in Windows

Microsoft Office applications can automatically save files to your OneDrive cloud account. However, problems with your OneDrive account or OneDrive’s synchronization settings will trigger “Upload Blocked” errors in Office applications.

This tutorial covers possible solutions for OneDrive Upload Blocked errors in Office apps on Windows computers. The troubleshooting solutions below apply to all Office applications—Microsoft Word, Excel, Powerpoint, Outlook, etc.

1. Reconnect Your OneDrive Account

Microsoft reckons reconnecting your Microsoft account to the Office application will fix OneDrive sync errors. Connect your computer to the internet, open the affected Office application, and follow the steps below.

1. Open the File tab in the Office app.

1. Select Office Account on the sidebar and select Remove next to the active OneDrive or user account.

1. Select Yes on the pop-up window.

1. Open the Add a service drop-down menu to reconnect your OneDrive account to the app.

1. Select Storage and then OneDrive. Select OneDrive for Business if you use a “Microsoft 365 for Business” account.

Enter your Microsoft account email and password to proceed. Try saving the document to OneDrive again and check if reconnecting your account resolves the “Upload Blocked” error.

2. Resume OneDrive Synchronization

Pausing OneDrive’s synchronization can cause Microsoft Office applications to throw the “Upload Blocked” error. Check OneDrive’s settings and ensure your computer is syncing files to the cloud storage.

1. Right-click the OneDrive icon on the Taskbar—see the bottom-right corner of your PC’s screen. OneDrive synchronization is disabled if there’s a “Your files are not currently syncing” message on the screen.
2. Select the gear icon and select Resume syncing to re-enable OneDrive’s synchronization.

Try saving the document again when OneDrive displays the “Your files are synced” message.

3. Verify OneDrive’s Storage Availability

Office applications won’t save or synchronize documents to OneDrive if you exhaust your storage quota. If the “Upload Blocked” error persists, check that you haven’t used up your OneDrive storage.

1. Open the OneDrive menu on the Taskbar, select the gear icon, and select Settings.

1. Head to the Account tab and check how much free OneDrive storage is linked to your account. Select Get more storage to upgrade your Microsoft 365 account for more OneDrive storage space.

4. Delete the Office App’s Cache Files

Corrupt cache files in Office apps can block document upload to OneDrive. Deleting files in the cache system of the affected Office application may fix the “Upload Blocked” error.

1. Open the Office app’s File menu, select More on the sidebar and select Options.

1. Open the Save tab, scroll to the “Cache Settings” section, and select the Delete cached files button.

1. Select Delete Cached Files on the pop-up window and select OK to save the changes.

5. Reopen the Office App

Force close the Office application if the “Upload Blocked” error persists after reconnecting your OneDrive account. If you haven’t saved the document locally (on your computer), we recommend pasting the content elsewhere as a backup. Say you’re working in Microsoft Word; copy and paste the content of the Word document to Google Docs.

Press Ctrl + Shift + Esc to open the Windows Task Manager. Select or right-click the Office application and select End task.

Reopen the app and check if it syncs changes made to your document to OneDrive.

6. Update the Office Application

Office updates ship with new features, security patches, bug fixes, and other improvements. Microsoft rolls out frequent updates to Office applications and automatically installs updates on your device.

The “Upload Blocked” error could be because you’re using an old or outdated version of the Office app. Configure your Office apps to update automatically, or manually check for new updates. Connect your computer to the internet and follow the steps below to update Office to the latest version.

Open the affected Office application and open the Account tab in the file menu. Expand the Update Options menu and select Update Now.

Select Enable updates if “Updates Now” is missing in the update menu.

7. Disable Office Upload Cache System

In Windows, OneDrive co-synchronizes files in Office applications. The integration has some benefits—it allows you to co-edit and work on shared documents with other people. However, you may get the “Upload Blocked” error message if OneDrive and Office upload cache systems are interfering.

Turning off the Office upload in OneDrive’s settings may resolve the “Upload Blocked” error.

1. Select the white or blue OneDrive (cloud) icon on the Taskbar’s notification area. If the icon is missing in the notification area, expand the Show hidden icons menu and select the OneDrive icon.

1. Select the gear icon in the top-right corner of the OneDrive menu and select Settings.

1. Head to the Office tab and uncheck Use Office applications to sync Office files that I open. Select OK to save the changes.

8. Repair Office

Repair the Microsoft Office application if none of the troubleshooting fixes above resolve the “Upload Blocked” error.

1. Press Windows key + X and select Install apps (or Apps and Features in Windows 10) on the Quick Access menu.

1. Select the menu icon next to the affected Office app and select Modify.

1. Select either Quick Repair or Online Repair and select the Repair button.

“Quick Repair” is a faster repair option that only detects and fixes corrupt files causing the Office app to malfunction. “Online Repair,” on the other hand, provides comprehensive repair and fixes every likely problem. Note that “Online Repair” requires an internet connection.

Microsoft recommends running an “Online Repair” only if a “Quick Repair” doesn’t resolve the problem you’re trying to fix.

1. Select Repair on the confirmation prompt to start the operation.

1. If any Office app is open, you’ll get a prompt to close the app. Save your document in the app before you proceed. Select Continue to grant the repair tool permission to close the app.

The tool will repair all Office programs and features on your computer.

1. Close the tool and reboot your computer when the repair operation is complete.

9. Update Windows

OneDrive-specific bugs in the Windows operating system can prevent Office apps from uploading documents to the cloud storage platform.

Go to Settings > Windows Update and select Check for updates or Restart now.

In Windows 10, head to Settings > Update & Security > Windows Updates and install any update available for your computer.

Reinstall Office

Contact Microsoft Support or uninstall and reinstall the Office application if the error persists after trying these fixes.
