Methods to Import PST to Exchange Online Archive

To migrate Outlook emails to Office 365 mailbox, you can try both manual and professional solutions. The migration process for PST to Online Archive Office 365 folder is very simple and straightforward. Follow the steps to perform migration-

Step 1: Storage Provisioning

For storage provisioning in Office 365, you need to sign in to your Office 365 account.

  1. Go to Import Service>Data Migration in Office 365.
  2. You will see the Upload PST file option; click that option.
  3. After that, click the + icon and select the Upload Email Messages (PST files) option.
  4. To import the PST file for the first time, you need to create a storage account. Click Show network upload SAS URL, which contains the following information:
    • Storage account name.
    • Container name.
    • Shared access signature: storage service version, expiration date, storage type, storage identifier, signature.
  5. This URL is specifically used to upload PST by the Azure AzCopy tool.

Step 2: Upload PST

Once the storage provisioning process is complete, you can start uploading the PST file. There are two options to upload the PST – use the AzCopy tool or Azure Storage Explorer. Here we will explain the Azure Storage Explorer process.

  1. Connect to Microsoft Azure Storage Explorer.
  2. Provide the Shared access signature URL or an account key.
  3. You’ll be able to see the Connection Summary after entering the required SAS URL.
  4. Now, import the PST file using the Azure Storage Explorer tool.
  5. If you want to check the list of files available on Azure, you can use the below cmdlets:
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: Map the PST File

After uploading the PST file to Azure Storage, you need to create a CSV file. This CSV file can be used to map the PST files to mailboxes and destination folders.

Step 4: Importing PST to Office 365 Archive Folder

Once you are done with the PST mapping, you can import the file to Office 365. Click Finish to start importing the PST file to Online Archive in Office 365.

The above process is a little challenging, as it contains complicated steps. Also, it becomes difficult for users to understand and implement the steps properly.
