This lengthy procedure needs prerequisites like an admin account on Office 365 tenant, an admin role on Import Export Mailbox, and high upload bandwidth.

Step 1: Storage provisioning

a) Launch Office 365 and click on Import Service > Data Migration > Upload PST. b) Now click on the “+” sign and select “Upload email messages(PST files)”. c) For the first import, the Storage account will be created. Then, click on “Show network upload SAS URL”. The url includes storage account name, container name, and shared access signature.

Note: Shared access signature contains:

sv -> storage service version se -> expiration date sr -> storage type si -> storage identifier sig -> signature

Step 2: Upload PST

After completing the first step, i.e. storage provisioning, the user can now begin uploading PST files. The user can use the AzCopy tool(Command line tool) or Azure Storage Explorer(Graphical tool).

a) Connect to Azure Storage Explorer. b) Enter the “Shared Access Signature(SAS) URL” or an “account key”. After entering it, the user sees “Connection Summary”. c) Now import PST using the Azure Storage Explorer tool. d) To check the list of files present on Azure use:

New-AzureStorageContext -SasToken ($SharedAccessSignatureURL -split ‘?’ | Select-Object -Last 1) -StorageAccountName ($SharedAccessSignatureURL -split ‘.’ -split ‘//’)[1] | Get-AzureStorageBlob -Container ($SharedAccessSignatureURL -split ‘?’ -split ‘/’)[3] | Select-Object -ExpandProperty Name

Step 3: Mapping the file

When the PST file has been uploaded to Azure Storage successfully, we need to build a CSV file. The CSV file will be used to map the PST file to mailboxes and destination folders.

Step 4: Import PST

Now we need to import the PST mapping file and click on “Finish”. The PST file will be imported to the Online Archive in Office 365.
