Outlook Web App的一个常见问题是用户无法下载文件附件。原因可能很多，包括浏览器问题、ISP限制、可疑发件人、低带宽等。

无法从Outlook Web App下载附件^{(Outlook Web App)}

在进行任何特定故障排除之前，请确保您有良好的互联网连接，并且文件来自受信任的发件人。完成此操作后，请按顺序执行以下解决方案：

1. ^{(Run Outlook Web App)}在不同的浏览器上运行 Outlook Web App
2. 以 ZIP 格式下载文件
3. 将附件保存到 OneDrive
4. 使用 Outlook.com 精简版
5. 使用旧的 Outlook Web App
6. ^(Open)在浏览器模式下编辑^(Edit)打开然后下载
7. 使用 Outlook 客户端

1]在不同的浏览器上运行 Outlook Web App^{(Run Outlook Web App)}

由于问题可能与损坏的缓存和 cookie 文件有关，隔离原因的一个好方法是在不同的浏览器上运行Outlook Web App 。如果在其他浏览器上运行Outlook Web App^{(Outlook Web App)}时无法轻松下载文件，请考虑清除浏览器缓存和 cookie^{(clearing the browser cache and cookies)}。

2] 将文件下载为 ZIP

由于某些系统和浏览器会阻止下载某些类型的文件格式，因此您可以考虑将附件下载为ZIP文件，因为系统肯定会接受这种格式。下载后，您可以提取系统本身的内容。

要将附件下载为ZIP文件，请找到下载全部^{(Download all)}选项，如屏幕截图所示。然后单击它以将一堆附件下载为ZIP文件。

但是，此过程的限制是您必须批量下载附件。您既不能下载单个附件，也不能下载一堆。

3]将附件保存到OneDrive

如果您无法直接下载附件，请考虑将其保存到OneDrive。如果OneDrive已连接到您的系统，您将能够直接从文件资源管理器^{(File Explorer)}访问它。

单击^(Click)附件旁边关联的向下箭头，然后选择Save to OneDrive。这有助于访问系统上的单个文件。

4] 使用 Outlook.com 精简版

使用 OWA 轻型版本并查看。

要使用OWA 精简^(OWA)版，请在附加邮箱的URL中添加“?layout=light” ，例如：

https://owa.contoso.com/owa/[email protected]/?layout=light

5]使用旧的Outlook Web App

较新版本的Outlook Web App充满了惊人的功能，但这是有代价的。这些附加组件使应用程序变得沉重，并且无法下载附件等故障很常见。

因此，您可以考虑使用旧的 Outlook Web App^{(old Outlook Web App)}来解决这个问题。

6]在浏览器模式下编辑^(Edit)打开^(Open)然后下载

某些文件格式（如MS Office^{(MS Office)}在线支持的文件格式）可以通过浏览器本身打开。您可以单击文件旁边的向下箭头。

如果您找到“在浏览器中编辑”^{(Edit in Browser)}选项（通常与MS Office 相关的^{(MS Office-related)}文件），请单击它。一旦文件在浏览器上打开，然后从Microsoft Online下载它。

7]使用Outlook客户端

使用Microsoft Outlook客户端从其他邮箱打开或下载附件。

Unable to download attachments from Outlook Web App

A commonly reported issuе with Outlook Web App is that users are υnable to download file attaсhments. Τhe reasons сould be many inclυding browser issυes, ISP restrictions, suspicious sender, low bandwidth, etc.

Unable to download attachments from Outlook Web App

Before proceeding to any specific troubleshooting, please make sure that you have a good internet connection, and the file is from a trusted sender. Once this is done, proceed with the following solutions sequentially:

1. Run Outlook Web App on a different browser
2. Download file as ZIP
3. Save the attachment to OneDrive
4. Use Outlook.com light version
5. Use old Outlook Web App
6. Open in the Edit in browser mode and then download it
7. Use Outlook client

1] Run Outlook Web App on a different browser

Since the issue could be with corrupt cache and cookie files, a good way to isolate the cause would be to run Outlook Web App on a different browser. If you are unable to download the file easily while running Outlook Web App on a different browser, then consider clearing the browser cache and cookies.

2] Download file as ZIP

Since certain systems and browsers block the downloading of certain types of file formats, you could consider downloading the attachments as a ZIP file because that will be accepted by the system for sure. Once downloaded, you can extract the contents on your system itself.

To download the attachments as a ZIP file, locate the option to Download all as shown in the screenshot. Then click on it to download the bunch of attachments as a ZIP file.

However, the limitation of this procedure is that you will have to download the attachments in bulk. You can neither download a single attachment, not a bunch.

3] Save the attachment to OneDrive

If you cannot download the attachment directly, consider saving it to OneDrive. If OneDrive is connected to your system, you will be able to access it directly from the File Explorer.

Click on the downward-pointing arrow associated next to the attachment and select Save to OneDrive. This is helpful for accessing individual files on your system.

4] Use Outlook.com light version

Use the OWA light version and see.

To use the OWA light version, add “?layout=light” to the URL of the additional mailbox, eg:

https://owa.contoso.com/owa/[email protected]/?layout=light

5] Use old Outlook Web App

The newer version of the Outlook Web App is full of amazing features however, that comes at a price. These add-ons make the application heavy and glitches like being unable to download attachments is common.

So, you can consider using the old Outlook Web App to overcome this problem.

6] Open in the Edit in browser mode and then download it

Some file formats like the ones supported by MS Office online can be opened through the browser itself. You can click on the downward-pointing arrow next to the file.

If you find the Edit in Browser option (usually with MS Office-related files) then click on it. Once the file opens on the browser, then download it from Microsoft Online.

7] Use Outlook client

Use the Microsoft Outlook client to open or download attachments from additional mailboxes.
