Why Export Microsoft 365 Mailbox to CSV Format?

Businesses export their mailbox data to a CSV format for improved accessibility and offline viewing. Here are the reasons why users consider exporting to CSV:

  • The CSV format makes the Office 365 email data into a well-structured format. This is useful for data analysts to analyze the data and reports.
  • Users often export their Office 365 emails to a CSV format to store the data securely for long-term purposes.

Different Ways to Export Office 365 to CSV

Now that we have understood why users export emails to CSV format, let’s proceed

Manually Export Emails from Office 365 to CSV

In this method, we will use Outlook’s built-in Import/Export feature. This method is ideal for exporting only a limited number of emails. First, make sure to configure your Office 365 account in MS Outlook.

Here are the steps to begin the process:

  1. Open the Outlook application on your system.
  2. Then, click on the File tab and choose Open & Export.
  3. After that, select Import/Export > Export to a file.
  4. Click Next and choose the Comma Separated Value (CSV) as the saving format. Again, click Next.
  5. Now, select the mailbox you want to export and pick the destination to save the resultant file.
  6. In the end, click on Finish to complete the process.

Limitations: This method will only export one email at a time. Therefore, bulk exporting will be time-consuming. Also, attachments will not be exported to a CSV file.
