What is the Need to Migrate the PST File to Microsoft 365 Mailbox?
Organizational policies Many companies have mentioned in their policies to migrate all their essential Outlook PST files to Microsoft 365 mailbox for security or backup purposes. This can also happen when an employee switches to a new organization and starts with Microsoft 365 account.
Creation of a new account When you are using some other email account and need to create a new mailbox, it is required to migrate PST files from Outlook to receive all the important information even in the new one.
Periodic backups Taking backup of all the essential data is a wise habit. Users often back up all their PST data to keep it safe from any kind of data loss and other risks. This is a precautionary measure that should be taken on a regular basis.

How to Migrate Outlook Emails to Microsoft 365, Manually?
For importing PST files manually to the Microsoft 365 mailbox or performing mailbox migration to Microsoft 365, we’ll first need to configure Microsoft 365 account in MS Outlook. Then, you need to use its Import/Export feature. To do this, follow the steps below
Open Outlook, click the File tab, click Open & Export, and select Import/Export.
Select Import from another program in the Import and Export wizard and click Next.
Select Outlook Data File (.pst) and click Next.
Browse for the Outlook PST data file, select it and click Next.
Set Options according to your preference to manage duplicate items in the file and click Next.
Note: If the PST file is password-protected, enter the password, and unlock it, click OK.
Choose the Import items to the same folder in the option and select the Microsoft 365 mailbox; Click Finish.
That’s it! You have imported the PST file to your Office 365 mailbox.
That’s it! The manual method is crisp, and there is nothing to worry about except some of its limitations-
Need to configure Office 365 account in Outlook.
It does not work for large-sized PST files. Mailbox files especially those of more than 150GB do not migrate at all.
It can migrate only a single mailbox at a time.
The chances of data loss are high.
It is quite a lengthy process as only a single mailbox is migrated at once.
There isn’t any guarantee of complete data migration. Chances are that some data might be missing.
It is not suitable for a complete beginner. The user must have knowledge about Outlook to some extent.
No PST import reports are available.
However, there are two more methods from Microsoft (Network Upload Method & Driving Shipping Method), which can be used to import PST files to Microsoft 365 mailboxes.
Let us have a close look at those methods:
A. Network Upload Method to Import PST to Microsoft 365
The Network Upload method is a great way and free approach to importing PST data to Microsoft 365. It allows administrators to import their entire PST data to Microsoft 365 using the Azure AzCopy tool. But keep in mind that the PST file should be stored on a file server or shared folder in your organization before migrating it to Microsoft 365. The steps involved in the Network upload method are:
Copy the SAS URL & install the Azure AzCopy tool.
Upload the PST file to Microsoft 365.
Create the PST Import mapping file.
Create a PST Import job in Microsoft 365.
Filter the data and run the PST import job.
Some shortcomings of this method-
This method allows you to export one PST file at a time; if you want to export more PST files to Microsoft 365, then you will have to repeat the same process or use a CSV file.
The process is complex and time-taking when moving multiple PSTs to the cloud destination.
This needs a decent amount of technical knowledge otherwise chances of PST files getting corrupt are high.
B. Drive Shipping to Import PST to Microsoft 365
Drive Shipping is another way to import PST data to Microsoft 365, which works by using a Secure storage key and PST Import Tool. However, this method is to be carried out only by the administrators and the organization whose data is being migrated. In this method, you will have to copy your PST data to a hard drive and then ship it to one of the physical locations of Microsoft 365. The steps involved in the Drive Shipping method are:
Download the secure storage key and PST Import tool.
Copy PST data to the hard drive.
Create a PST Import mapping file.
Create a PST Import job in Microsoft 365.
Ship the hard drive to Microsoft.
Filter the data and start with the import job.
The drawbacks of this method are-
Needs to send the PST data to Microsoft in a hard disk drive
It takes 1-2 weeks to import the PST data to Microsoft 365, and every organization cannot wait for such a long period.
It is not convenient when there is an urgency to upload PST to Microsoft 365.
Also, the method is not free and costs money per GB of data which can be expensive for small organizations.
If organizations have to import PST files to multiple Microsoft 365 mailboxes, it would be a pain for Office 365 administrators.
Both Network Upload and Drive Shipping methods are highly technical in nature and can be easily mishandled by users leading to incomplete migration or data loss, or corruption.
All these shortcomings in the manual procedures are a wake-up call for the users, and then they may use automated tools to import PST files to one or more Microsoft 365 mailboxes.
