Step 1: Copying SAS URL & installing azure AzCopy
First, you’ll have to download and install the Azure AzCopy tool on your system, which will be used in the next step to upload PST. Also, you’ll have to copy the SAS URL for your organization.
Note: SAS URL is the combination of network URL for the Azure storage location and a Shared Access Signature key that provides the permissions to move PST files to Azure storage location.
For downloading and installing the Azure AzCopy tool and copying the SAS URL, follow the below steps:
- Visit https://protection.office.com/ and sign in to Office 365 administrator account for your organization.
- Look for Security and Compliance Center in the left pane and click Data governance >> Import.

- Running the command will display the status message of uploading the PST file in progress. A final status message will display the total number of files uploaded to Azure storage location.
If you want to check the list of the PST files uploaded to the Azure blob, then you can use the open-source Microsoft Azure Storage Explorer tool.
Step 3: Creating the PST mapping file
