Hello, in this post we are going to see how to export an Office 365 (Exchange online) mailbox content to a PST file. This process can also be used to search for SharePoint, OneDrive, Teams sites, Office 365 group… content. Now that we have set the scene, we can get started.
In the Security and compliance center (https://protection.office.com), under “Search” click on “Content Search”
In the content search portal, start a New search
Check “Specific location” and select modify to specify the location/mailbox you want to export the content from.
On the next tab, click on “choose users, groups or teams” and specify the mailbox for which you want to export the content to PST.
Select the checkbox and click on Choose, selct Done and on the next tab click on Save to validate your choice.
Save and run to start the content search process.
Give a name to your content search process and click save to start the search.
Once the content search of the mailbox you specified is done, in the menu select Export results.
In the next tab, select the export options according to your need and click on “Export”
The export process has now started, you can see the status in the Exports tab by clicking on the name you gave to your export.
Once the export status is completed, you now can start downloading the result.
Clique on “Copy to clipboard” to copy the “Export secret” and click on “Download the result”. On the next page, enter the Export secret and specify the location where to save the pst file.
Start the downloading process – sorry, my OS is in french version 🙂 . At the end of the downloading, retrieve the pst file in the location you previously specified.
