Are you Looking to Import PST File in Office 365 (Exchange Online)? If yes then you have landed at right place. Here in this How To Tutorial I will explain simple steps of Importing the Outlook PST file in Office 365 Environment.

Steps to Migrate PST file to Office 365

Users can use the Office 365 Import Service of Microsoft to Move PST emails, calendars, tasks, etc. to Office 365.

Step 1: Share Folder that contains PST file

First of all Share the folder of PST file with everyone. For that Open Properties of Folder by right clicking on it. Now switch to Sharing Tab and click on Share button.

Now Share the folder with Everyone. This will generate the Server Path of PST file and this path will be used to Import the data of PST file in Office 365.

Step 2: Now Access the Import Service of Office 365

From the Office 365 Admin Center click on Import option. Now Click on the plus sign from the middle pane. Here you will find two options:

  • Ship data on physical hard drives
  • Upload files over network.

For importing the data of PST file in Office 365 we will use the second method i.e. uploading files over the network.

Step 3: Download the Azure AzCopy Tool

In the next step Download the Azure Tool by clicking on the Download Tool link. It is a command line tool that helps in uploading the data to Azure.

After that Click on Next two links (Show key and Show URL). These Links will generate Security key and Unique URL. This Key and URL will be used with the AzCopy command to upload the data of PST file to Azure.

Step 4: Run the Command on Azure Tool to Upload the data

Now Upload the data over Azure by running the command given below:

AzCopy.exe /source:\\SERVER\SHARE /dest:{your unique URL}/SERVER/SHARE /destkey:{your unique key} /S /V:C:\Logfile\import.log

  • \\Server\SHARE >> Replace this with the Server Path of PST file that you have copied previously.
  • {your Unique URL} >> Replace this complete string with the URL (Enter the URL without braces {})
  • {your Unique key} >> Replace this complete string with the Key (Enter the URL without braces {})
  • C:\LogFile: This will store the import.log file in a Folder LogFile in C drive.

This process will take some time and it depends upon the Size of your Outlook PST.

After the successful upload operation, Make a check on both the fields as shown below and then click on Next button

Step 5: Move the uploaded PST file to the Corresponding Mailbox
