Many users, like the one mentioned above, encounter similar issues while importing their mailboxes to Office 365. They are unaware of the most appropriate method to use.

As technology evolves, individuals and organizations embrace the latest cloud technology, such as Office 365. Many prefer to migrate their .pst files to Office 365 to leverage its user-friendly interface.

Before discussing the methods, let’s first explore the different scenarios for importing PST files to Exchange Online.

Why Import Outlook Folders to Office 365?

First and foremost, PST files are delicate and prone to corruption if left unused for extended periods. To safeguard your vital data, the only solution is to import Outlook folders to Office 365.

Furthermore, consider a scenario where an organization has backed up all sent emails in PST format on their desktop. Now, there arises a requirement to access these sent items for investigation purposes. To open these important files, it becomes necessary to import the PST files to Office 365.

Hence, importing Outlook PST files to Office 365 is a proactive measure to ensure data integrity.

However, it’s important to note that manual methods have their limitations, which is why IT administrators often prefer the automated approach due to its various advantages.

Let’s discuss each method in detail, starting with the manual methods.

Manual Import of Outlook Folders to Office 365

If you only have a few PST files to import to Office 365, you can use the Import/Export Wizard, a native method supported by Microsoft. Follow these steps after configuring your Outlook account:

  • Open MS Outlook, go to the File tab and click on Open & Export >> Import/Export.
  • In the next window, select the file type, Outlook Data File (.pst), and click “Next.”
  • Choose the desired PST file path to import by clicking the Browse button.
  • Select the “Include subfolders” option to import the entire file.
  • Provide your Office 365 ID and click “Finish.”
  • Please note that this method is not suitable for users looking to import a large number of Outlook files.

Import Outlook Archive to Office 365 Using Drive Shipping Method

The Drive Shipping Method can be employed for bulk import of PST files, albeit for $2 per GB of data to be imported.

In this method, you need to copy the PST files to a hard drive and physically send them to Microsoft. Once Microsoft receives the hard drive, their representative will proceed to transfer the PST files to your Office 365 account. However, it’s important to note that this facility is available only in limited countries, and there is a maximum limit of sending 10 drives at a time.

Considering the cost and convenience, this method is not recommended if you have a large amount of data, such as several terabytes.

The Network Upload Method is the next option, which involves a technical approach using the PowerShell scripting language. Before attempting this method, it is crucial to have expertise in the language. Otherwise, you may encounter unsatisfactory results, as discussed earlier, or even risk data corruption.

Therefore, it is evident that manual methods cannot be considered as a one-stop solution for importing data.

Fortunately, an automated method exists that overcomes the challenges associated with manual methods.
