PST file to Office 365 migration

A switch to Office 365 is the perfect opportunity to eliminate the support, storage, information governance and eDiscovery headache that PST files cause for many enterprise customers.

PSTs can be literally anywhere on your network, and can contain unknown content (including a lot of rubbish and duplicates); making tackling PSTs a highly complex task, demanding significant ‘horsepower’ and sophisticated functionality.

TransVault PST Insight gives business and IT managers the power to find PSTs across the enterprise, understand what’s in them and manage their contents in line with business, compliance and operational needs. Designed for large and complex PST management projects, PST Insight delivers unrivalled scalability and flexibility.

It also gives the auditing and one-step transfer assurance that let you tackle your PST headaches with confidence.

Manage Contents in line with Data Policies

TransVault PST Insight lets you manage PST contents in line with enterprise compliance and business needs, using PST Insight’s granularity and flexibility to enforce the necessary PST content management policies. 

For example, you might decide to:

  • migrate all or just a subset of PST contents centrally
  • delete ‘in place’ any contents that fall outside of your retention policy.
  • search for shortcuts that have been put in PSTs, & either delete or re-hydrate them with the full item.

Bringing order to your PST files….

Without Insight’s ability to scan within the PSTs, we would have needed to pull back 10 times the volume of email data, significantly increasing the data capture time and delaying eDiscovery. It goes without saying, by minimizing what needed to be moved, we also avoided an adverse performance hit on our network.

Slick, One-step Migrations

Migration is direct from PST to Office 365 – there’s no interim stages or file formats that add time, complexity and risk to your move.

Delivered On-premises or SaaS

The first PST management solution to be delivered via Microsoft’s Azure Marketplace, PST Insight is a multi-tiered on-demand solution that delivers exceptionally scalability & ease-of-deployment for managing & migrating highly-distributed enterprise PST files. 

Unbeatable Ingestion Speeds

TransVault’s state-of-the-art CloudStream technology ensures you get optimum on-boarding performance into Office 365.

Unrivalled, Content-Level Insight

Unlike other PST management tools, TransVault PST Insight gives you unrivalled visibility of the individual emails in PST files.  It will help you profile PST contents according to age, size, attachment type and many other criteria, generating detailed management reports that illustrate the risk and storage burden PST files represent to your company.

Accelerate PST eDiscovery

TransVault PST Insight supports the eDiscovery process, enabling analysis & targeted collection across many thousands of PSTs without having to first migrate all their contents centrally.

TransVault PST Insight also helps avoid over-collection of data by way of targeted ingestion that reflects existing retention policies.


PST Insight’s unique dashboard allows you to monitor how well your PST management policies are progressing over time (bearing in mind that tackling PSTs can be a long-term project).

Insight also gives you a high degree of functionality and control, enabling you to cope with situations such as corrupted emails, locked PSTs and more.
