Microsoft Outlook使用PST文件来存储电子邮件帐户的数据，包括所有邮件、联系人、文件附件等。您可以转换PST文件以将电子邮件保存为不同的格式，这种格式可能更易于在其他程序中使用。

当您转换PST文件时，您的电子邮件将以完全不同的文件格式存在，然后可用于在没有Outlook的情况下查看电子邮件。如果您不再对Outlook感兴趣，或者您想确保无论将来使用哪种电子邮件客户端都可以始终保留您的电子邮件，那么您将需要转换您的PST文件。

以下是处理PST文件的几种方法，例如直接转换它或从中提取电子邮件。

首先制作 PST 文件^{(Make The PST File First)}

将PST^(PST)转换为另一种格式的第一步是将所有电子邮件导出为 PST 格式^{(export all your emails to the PST format)}。

1. 转到文件^{(File )}>打开和导出^{(Open & Export)}>Import/Export。
2. 选择导出到文件^{(Export to a file)}。
3. 选择下一步^(Next)。
4. 选择Outlook 数据文件 (.pst)^{(Outlook Data File (.pst))}。
5. 单击下一步^(Next)。
6. 选择收件箱^(Inbox)上方的最顶层文件夹，以确保备份整个电子邮件帐户，包括所有子文件夹。如果未选中包含子文件夹选项，请在继续之前勾选该框。^{(Include subfolders)}
7. 选择下一步^(Next)。
8. 使用浏览^(Browse)按钮选择计算机上应存储PST文件的文件夹。^(PST)
9. 选择完成^(Finish)。
10. （可选）密码保护您的PST文件，然后选择“确定^(OK)”将Outlook电子邮件导出为PST格式。

决定你想要的格式^{(Decide Which Format You Want)}

如果您甚至不确定下一步要做什么，那么将您的PST文件保存为另一种格式是不明智的。您最终可能会得到一堆与您想要使用电子邮件的目的不兼容的奇怪格式。

• 将PST^(PST)文件保存在Gmail/Yahoo/etc中是您的最终目标吗？帐户，与您所有其他电子邮件合并并永远在线保存？ 
• 您是否希望您的电子邮件以PDF格式存在，以便您可以轻松访问每封电子邮件？ 
• ^(Are)您想要保存的PST^(PST)文件中 是否只有几条消息？
• 您是否只有一个非常旧的PST文件想要从中接收电子邮件，但未安装Outlook让您阅读它们？

一旦您决定如何使用转换后的PST文件，请选择下面适用的教程。

将 PST 电子邮件与您现有的电子邮件帐户合并^{(Merge The PST Emails With Your Existing Email Account)}

如果您希望PST文件中的电子邮件与您在Yahoo、Outlook.com、Gmail等 的现有电子邮件帐户合并，请按照以下步骤操作。

这实际上会将PST文件上传到该服务，以便来自PST文件和您的其他电子邮件帐户的所有电子邮件都将存在于所有同步设备上的同一位置。

1. 将您的电子邮件帐户（例如Gmail、Outlook.com等）添加到Outlook，以便您可以在Outlook中查看所有电子邮件。让它与您的计算机完全同步。
2. 在 Outlook 中，转到文件^{(File )}>打开和导出^{(Open & Export)}>Import/Export。
3. 选择从另一个程序或文件导入^{(Import from another program or file)}。
4. 选择下一步^(Next)。
5. 选择Outlook 数据文件 (.pst)^{(Outlook Data File (.pst))}。
6. 选择下一步^(Next)。
7. 使用浏览^{(Browse )}按钮查找备份的PST文件。
8. 选择^{(Choose one)}复制选项之一，例如用导入的项目替换重复项^{(Replace duplicates with items imported)}或不导入重复项^{(Do not import duplicates)}。
9. 选择下一步^(Next)。
10. 从PST文件中选择要转换为现有电子邮件帐户的文件夹。例如，选择Inbox将转换^(Inbox)Inbox中的所有电子邮件。
11. 如果您也想转换这些电子邮件，请标记包含子文件夹选项。^{(Include subfolders)}
12. 选择将项目导入同一文件夹^{(Import items into the same folder)}，然后选择要将电子邮件转换到的文件夹。
13. 选择完成^(Finish)。
14. 等待^(Wait)电子邮件同步以将PST消息保存在您的Gmail帐户（或您将其转换为的任何帐户）中。

将 PST 转换为 PDF、JPG 和其他格式^{(Convert PST To PDF, JPG, & Other Formats)}

不幸的是，似乎运行良好的免费PST到PDF转换器并不多。一种选择是使用像CutePDF这样的^(CutePDF)PDF“打印机” 。将其安装在您的计算机上，选择要保存为PDF的电子邮件，然后选择该打印机而不是真实打印机。此方法会将PST文件中所有选定的电子邮件放入单个长PDF中。

其他一些选择包括Kernel for Outlook to PDF、CubexSoft Outlook Export（一次限制为 20 个免费）、PST 到 PDF 向导^{(PST to PDF Wizard)}（仅前 25 个免费）、PST Viewer Pro（前 50 个免费）、SysTools Outlook PST到 PDF^{(SysTools Outlook PST to PDF)}（25 次免费转换）。

电子邮件 Open View Pro^{(Email Open View Pro)}是前 30 天免费的另一个示例，但它会在文档上添加水印，并强制您将所有选定的电子邮件合并到一个大PDF中。

同一个程序可以将电子邮件批量转换为图像格式，这非常方便，但同样，除非您付费，否则水印仍然存在。支持的格式包括JPG、GIF、PNG、EMF等。

另一种选择是将PST文件转换为一堆EML文件，这是另一种消息文件格式，但它与许多电子邮件客户端兼容，而不仅仅是Outlook。上面链接的程序可以为您做到这一点。

虽然这种方法有点费时，但有一种方法可以将您的PST文件转换为PDF^(PDFs)，其中每封电子邮件都是一个单独的PDF文件。为此，从PST生成^(PST)MSG文件，方法是将它们拖出Outlook或使用Email Open View Pro（它不会在MSG文件上留下水印）。 

然后，将所有 MSG 文件上传到PDFpen以将它们保存为PDF^(PDFs)。此工具可免费批量转换五个，或者您可以购买许可证^{(buy a license)}以同时管理更多转换。

如果您使用的是 Mac，Stellar Converter for PST可以将PST文件保存到MBOX，以便您可以使用Apple Mail打开电子邮件。

从 PST 文件中保存单个电子邮件^{(Save Individual Emails From The PST File)}

如果您只想保存少量电子邮件，则无需转换整个PST文件。从PST^(PST)中选择要转换的消息，然后按照以下任一方法进行操作：

• 将^(Drag)电子邮件拖出Outlook并放入文件夹中。当您这样做时，电子邮件会变成一个MSG文件，您可以在线打开该文件，也可以使用^{(you can open online)}FreeViewer MSG Viewer、Email Open View Pro和Free Opener等离线工具打开该文件。
• 打开您要保存的电子邮件并使用“文件^(File)” > “另存为^{(Save As)}”菜单将其保存为TXT、MHT或HTML，这三种格式与 Outlook 无关。

How To Bulk-Convert Outlook PST Files Into Another Format

A PST file is used by Microsoft Оutlook to store an email account’s data, including all the mеssages, contacts, file attachments, and more. You can convert a PST file to save your emails in a different format, one that’s perhaps easier to use in other programs.

When you convert a PST file, your emails will exist in an entirely different file format that can then be used to view the emails without Outlook. If you’re no longer interested in Outlook or you want to ensure that you can always keep your emails no matter what email client you use in the future, you’ll want to convert your PST file.

Below are several ways to deal with a PST file, like converting it outright or extracting emails from it.

Make The PST File First

The first step in converting PST to another format is to export all your emails to the PST format.

1. Go to File > Open & Export > Import/Export.
2. Select Export to a file.
3. Choose Next.
4. Pick Outlook Data File (.pst).
5. Click Next.
6. Select the very topmost folder, above Inbox, so that you make sure your entire email account is being backed up, including all subfolders. If the Include subfolders option isn’t checked, tick the box before continuing.
7. Select Next.
8. Use the Browse button to select a folder on your computer where the PST file should be stored.
9. Select Finish.
10. Optionally password-protect your PST file, and then select OK to export your Outlook emails to PST format.

Decide Which Format You Want

It’d be unwise to save your PST file in another format if you’re not even sure what you want to do next. You might end up with a bunch of strange formats that are incompatible with what you want to use the emails for.

• Is your ultimate goal to save your PST file in your Gmail/Yahoo/etc. account, merged with all your other emails and forever saved online? 
• Do you want your emails to exist in the PDF format so that you’ll have easy access to every email? 
• Are there just a few messages from the PST file that you want saved? 
• Do you just have a really old PST file that you want the emails from, but Outlook isn’t installed to let you read them?

Once you decide how you want to use your converted PST file, choose a tutorial below that applies.

Merge The PST Emails With Your Existing Email Account

Follow these steps if you want the emails from the PST file to be merged with your existing email account at Yahoo, Outlook.com, Gmail, etc. 

This will essentially upload the PST file to that service so that all the emails from the PST file and your other email account will be exist in the same place on all your synced devices.

1. Add your email account (e.g., Gmail, Outlook.com, etc.) to Outlook so that you can see all your emails in Outlook. Let it fully sync with your computer.
2. In Outlook, go to File > Open & Export > Import/Export.
3. Choose Import from another program or file.
4. Select Next.
5. Choose Outlook Data File (.pst).
6. Select Next.
7. Find your backed up PST file with the Browse button.
8. Choose one of the dupcation options, such as Replace duplicates with items imported or Do not import duplicates.
9. Select Next.
10. Pick the folder from the PST file that you want to convert into your existing email account. Selecting Inbox, for example, would convert all the emails in Inbox.
11. Mark the Include subfolders option if you want to convert those emails, too.
12. Select Import items into the same folder, and then pick which folder you want the emails to be converted into.
13. Select Finish.
14. Wait while the emails sync to save the PST messages in your Gmail account (or whatever account you’re converting them into).

Convert PST To PDF, JPG, & Other Formats

Unfortunately, there aren’t many free PST to PDF converters that seem to work well. One option is to use a PDF “printer” like CutePDF. Install it on your computer, select the emails you want to save to PDF, and then choose that printer instead of a real one. This method will put all the selected emails from the PST file into a single, long PDF.

Some other choices include Kernel for Outlook to PDF, CubexSoft Outlook Export (limited to 20 at a time for free), PST to PDF Wizard (only the first 25 are free), PST Viewer Pro (first 50 are free), SysTools Outlook PST to PDF (25 conversions are free).

Email Open View Pro is another example that’s free for the first 30 days, but it puts a watermark on the document and also forces you to merge all the selected emails in one large PDF.

The same program can convert email to an image format in bulk, which is really handy, but again, the watermark remains unless you pay for it. Supported formats include JPG, GIF, PNG, EMF, and several others.

Another option is to convert the PST file to a bunch of EML files, which is another message file format but it’s compatible with lots of email clients, not just Outlook. The program linked above can do that for you.

Although this method is a bit time consuming, there is a way to convert your PST file to PDFs where each email is a separate PDF file. To do that, produce MSG files from the PST, either by dragging them out of Outlook or using Email Open View Pro (it doesn’t leave a watermark on MSG files). 

Then, upload all the MSG files to PDFpen to save them as PDFs. This tool is free for converting five in bulk, or you can buy a license to manage more conversions simultaneously.

If you’re on a Mac, Stellar Converter for PST can save the PST file to MBOX so that you can open the emails with Apple Mail.

Save Individual Emails From The PST File

If you have just a handful of emails that you want to save, you don’t need to convert the whole PST file. Pick the messages you want to convert out of the PST and then follow either of these methods:

• Drag the email out of Outlook and into a folder. When you do this, the email turns into an MSG file, which you can open online, or with offline tools like FreeViewer MSG Viewer, Email Open View Pro, and Free Opener.
• Open the email you want to save and use the File > Save As menu to save it to TXT, MHT, or HTML, three formats that are Outlook-independent.
