Enterprise PST, EML or NSF migration to Microsoft cloud

Our migration & management solutions offer a range of options for tackling email files, including PSTs and EMLs, at both a file & content-level.


Get in control of PST files

Don’t let PST files compromise your ability to govern & access enterprise data.

Massively outdated but still prevalent in many large enterprises, PST files are the enemy of any data modernisation strategy.

They are typically located on local hard disks and therefore difficult to secure and backup. Their contents are also virtually impossible to search and manage in line with business and compliance needs.

By moving PST contents into the cloud, you can give end users secure access to their data from any device, anywhere.

You can also protect and manage the contents of PST files in accordance with centrally defined policies.

This all sounds great, but the challenge with ingesting PST files into Microsoft cloud starts with locating them, uploading them (and tracking upload progress), mapping ownership and more. This is where Microsoft tools for ingestion into Microsoft 365 and Azure fall short.

And this is where Essential can help…
