The first step is to download and install the Azure AzCopy tool, which is the tool that you run in Step 2 to upload PST files to Office 365. You also copy the SAS URL for your organization. This URL is a combination of the network URL for the Azure Storage location in the Microsoft cloud for your organization and a Shared Access Signature (SAS) key. This key provides you with the necessary permissions to upload PST files to your Azure Storage location.
Now you're ready to use the AzCopy.exe tool to upload PST files to Office 365. This tool uploads and stores them in an Azure Storage location in the Microsoft cloud.
After the PST files have been uploaded to the Azure Storage location for your Office 365 organization, the next step is to create a comma-separated value (CSV) file that specifies which user mailboxes the PST files will be imported to. You'll submit this CSV file when you create a PST Import job.
