Step By Step Guide on How to Use Network Upload to Import .PST file in Microsoft 365

In this demonstration, we will upload the PST backup of Megan’s email to Joni’s Email. Below picture is of Megan’s where there are only 3 emails.

The .pst backup of this email is available on the folder name “megan-pst” .

Before importing the PST file, you need to be assigned with the “Mailbox Import Export Role” to create import jobs. By default, this role isn’t assigned to any role group in Exchange Online.

To assign the Role follow the steps below:

-Go to admin center and click on Exchange

In Exchange Admin Center,

-Click on Admin roles & Click on Organization Management

-Assign the User’s or the group for “Mailbox Import Export” Role.

-Now go to permissions, select the role, and Click on Save

-You may face the issue below. Don’t be panic, try to save with classic exchange admin; try with different browser or wait and try after some time.

Mailbox Import Export role is now assigned. In addition to this role, you also have to be assigned with “Mail Recipients” role in exchange Online.

After providing the necessary role permission. Go to the Compliance Portal

Go to Data lifecycle management -> Microsoft 365 -> Import -> New Import Job

Enter a Job Name & click on Next

Select “Upload your data” & click Next

Click on “Show Network Upload SAS URL

Now Download the AzCopy tool to Upload your files. Download link:

Install the AzCopy Tool

After completing, the installation process, open the AzCopy with administrator privilege.

Now you’re ready to use the AzCopy tool to upload PST files to Microsoft 365.This tool uploads and stores PST files in a Microsoft-provide Azure Storage location in the Microsoft Cloud.

Azcopy.exe /Source:”\\XPS-13\Users\XPS\Desktop\megan-pst " /Dest:”https://47**************************&sig=X2yc*****************VjP3W4DW******3D&se=2022-10-29*********3A09Z” /v:"C:\Users\XPS\Desktop\Log1\azcopy.log" /Y


/Source:”\\XPS-13\Users\XPS\Desktop\megan-pst”  is the source location (For example: megan.pst file location)

/Dest:”<SAS URL>” is the destination location

/v:"C:\Users\XPS\Desktop\Log1\azcopy.log" /Y where log is saved. (Create a log folder and include the path)

Based on your .pst file it will take time to process

Once you run the above command successfully, you will be able to see the output log in the log1 folder

Now you are ready to proceed with the next step that is preparing a CSV file. But before proceeding to the next step you can also verify that the files has been uploaded to the azure storage explorer successfully.

(Note: Verification in Microsoft Azure Storage Explorer is optional and is not mandatory)

To verify, download & install Microsoft Azure Storage Explorer. Connect using the SAS URL.

Paste the SAS URL


Now you can see the Megan.pst has been uploaded to azure storage and its verified that the megan.pst file is now upload to azure storage but still it need to be uploaded to the user mailbox.

 Now, let’s prepare the CSV file.

Leave everything as is it in the picture but under the Name field enter the .pst file name & in Mailbox field enter the email address in which you want to import.

(Note: You can also use the Target folder as /Inbox/OldEmails)

Now go back to the previous steps where we left and select the options available in point 4. & Click on Next.

Select the CSV file and Validate

After the successful validation click on Next
