How to Export Emails from Outlook Web App to PST File Format

All users who want to export emails from the Outlook Web App to PST may find the process troublesome. That is why in this tutorial we have put together an arsenal of ideas that can make the transition happen.

So let us start by deciphering the default method and also learn why it’s so frowned upon.

How to Export Emails from Outlook Web App to PST Manually?

For that, you need to complete these steps:

• Login to your Outlook web portal
• Click on the cog icon at the top right corner
  
• Go to the General tab
• Open the Privacy and Data section
• Click the Blue color Export Mailbox icon.
• The Export Mailbox icon Greys out and the text ‘Status: Export in progress’ appears.
  

Till here the manual process appears quite easy and rightly so. However, the real troubles start now.

Problems with Manual Export

First up you only see an ‘Export in progress’ text which has no meaning in itself. Like you just started the process of course you know that the export is ongoing.

Moreover, the biggest problem is the lack of a status bar.

Its absence means that once you start the process to export emails from Outlook Web App to PST neither do you know how much of the task is completed nor do you have any information on the % of data left for the export.

Thus making any predictions on the total download time is downright impossible. This is frustrating as it essentially freezes all your workflow.

You dont receive any updates on mail, you have to log in to Outlook and follow the entire path to the Export Mailbox icon to see the status.

Additionally, there are no explicit guidelines as to what would happen to the data that is generated while a current iteration of export is going on.

So all incoming and outgoing email conversations that occur are in limbo for up to 4 days. This is the timeline that Microsoft mentions on its Export mailbox page.

During a test run, even for a dummy account with ~ 10 emails, it took more than a day for the download link to appear. Such a slow rate of export is not acceptable in the modern workplace.

Another drawback of this DIY approach is that you cannot filter out any data before the export. This means it is an all-or-none kind of deal. There is no option to select folders, apply date filters, or prevent certain data from being part of the end result.

There is a way you can regain some control over the export i.e. by using the Outlook email client. So let’s see how.

Use the Client and Export PST from the Outlook Web App

You can’t use any client it has to be the classic version. Unfortunately, modern Windows machines only come with the new Outlook for Desktop.

This version is essentially a replica of the OWA so has all the demerits of the previously discussed export process. Slow, no filtering, and more.

That’s why we gravitate towards the Classic edition which had a more robust PST extraction feature.

As your PC may not have the client you first need to download a copy of the client and then follow the on-screen instructions to set up the application.

Once done continue with these steps.

• File Add Account
• Type in the account name, and mark the box next to Advance Setup.
• On the Next Screen Select Outlook.com
• Then choose the historical email you want to bring on the device. Range varies from 3 days to All emails that exist on your account.
• Press Next,
• Outlook Client is now connected to your Web account. Restart the client to see the changes.

To Export the Outlook Web account content from inside this client you have to:

• Go to File > Open & Export > Import/Export.
  
• Export to a File > Next.
• Outlook Data file (.pst) > Next.
• Select the OWA folder whose data you want in PST. You can apply advanced Filters as well.
• After the selections are made hit Next.
• Then browse for an on-device location, choose the option Replace duplicates, allow duplicates, or skip duplicates.
• Finally hit Finish.

Sometimes in your particular case, it might make sense to use a nontraditional approach. We have put together some of the less-known methods to pull out Outlook web data in a Portable Storage Table format. See if you qualify it can end up saving time and effort.

Unorthodox Techniques to Get Outlook Web Data in PST

These are highly situational and only apply to specific use cases. If you only plan to export out one or two emails but from multiple Outlook web accounts then neither the default export nor the complex account setup on the classic client is recommended. So what we suggest you do is:

• Hover over the mail
• Right click
• Select Save as an option from the flyout menu column
  
• Browse for the local folder where you wish to put this email and hit Save.
  

Note: The format you get is EML. Don’t manually alter the .eml extension to .pst it won’t change the file format. Moreover, doing this risks corrupting your data. Instead, use the state-of-the-art SysTools EML to PST converter and get the data in the desired format.

If you are in an Organization that is transferring from a personal Outlook to a unified Google Workspace environment then there is a strategy you can apply. Before that ensure that these pre-requisites are met.

• Your Organization has access to Google Vault.
• Admin has allowed users to add external Outlook accounts in the workspace
• Users who want to export emails from the Outlook Web App to PST have linked their accounts.

Then search for Outlook emails in Google Vault:

• Open Google Vault, go to Matters and create/select a matter.
• In the Search tab, select Gmail, enter the email account (Outlook account in Gmail), and apply search filters if needed.
• Run the search and review results.

Export Emails in PST Format:

• Save the search, click Export, and choose PST format.
• Monitor the export in the Exports tab and download the PST file when ready (available for 15 days).

Likewise, if your organization has transitioned to a Microsoft 365 subscription then you might be able to use the eDiscovery export tool similarly.
