There are two main methods considered the safest ways to import PST files into Exchange Online, prioritizing data security and minimizing errors:
1. Network Upload with Microsoft Purview Compliance Portal:
This method is considered the most secure and is generally recommended by Microsoft. Here's why it's safe:
Staged Upload: You upload PST files to a secure Azure Storage location, staged and separate from your Exchange Online environment.
Data Encryption: Files are encrypted in transit and at rest using industry-standard protocols during the upload process.
Error Handling: The import service automatically detects and handles potential errors or inconsistencies within the PST files before importing.
Here's what to consider for this method:
Technical Expertise: Requires some administrative privileges in Exchange Online to configure the import job.
PST File Size Limitations: There are limitations on the size of individual PST files you can upload using this method.
2. Drive Shipping with BitLocker Encryption:
While less common, this method can be an option if network bandwidth limitations or very large PST files are a concern. Here's why it can be safe:
Physical Security: PST files are physically shipped to a Microsoft data center on a secure drive.
BitLocker Encryption: The drive itself should be encrypted using BitLocker technology to ensure data privacy during transport.
Microsoft Responsibility: Once received by Microsoft, the data center handles the upload process with robust security measures.
Here's what to consider for this method:
Physical Security: You are responsible for ensuring the physical security of the drive during transit.
Turnaround Time: Shipping the drive and processing the upload can take longer compared to the network upload method.
Additional Tips for Safe PST Import:
Backup PST Files: Always maintain a backup copy of your PST files before initiating any import process.
Content Review: It's recommended to review the content of PST files beforehand to identify any sensitive information that might require special handling during migration.
Phased Approach: Consider a phased approach, especially for large migrations, to minimize disruption and allow for easier troubleshooting if issues arise.
Alternative Third-party Tool: For a seamless import process you can also consider Shoviv Outlook Suite software that allows to import and export of OST and PST files from Exchange Online.
