Hazards of PST Files

A HIGH SECURITY RISK

PST files are very portable; they can be removed from Outlook and copied or moved to other Outlook client with ease.

They can be protected using password, however internet is filled with several of programs that can crack these passwords.

This puts your data and intellectual property on high risk.

UNRELIABILITY CAUSES PRESSURE ON IT SUPPORT

PSTs are not designed to hold large email data yet people keep dumping emails into them

Once they crosses recommended size between 1 to 1.5 GB they often get corrupt.

Power outages, System crash or inadvertently closing the PST disconnects it from the Outlook

profile. It’s then usually overlooked or lost, creating orphaned PST which is invisible to SUpport teams.

They can still contain valuable information that needs to be preserved.

These files become major call drivers of an IT departments daily helpdesk calls.

FAILURE TO MEET COMPLIANCE REQUIREMENTS

PST is just a container file and does not fall under compliance requirements but the

content within it DO. If the IT department is not managing PST files, best practice is at stake.

INCREDIBLY ELUSIVE

PST files are generally located on desktops, laptops, shared storage, removable storage media, even home PCs.

Majority of users store PSTs on laptops and a few of them on portable storage devices.

Outlook needs access to theses locations in order to view the content, this works fine for users who have the same access to local or network storage, but if users work from different desktops or locations they may not be able to gain access to the PSTs. Also, if the OWA, Outlook Web App is used, users will have no access to these files.

STORAGE, BACKUP AND RESTORE PROCESS ISSUES

If PSTs located on desktops or laptops fall outside the corporate backup strategy, they’re neither backed up nor protected. If located on network shares, they’re probably being backed up, but this also brings challenges. Each time Outlook connects to a PST, it’s marked as requiring backup.

There is massive impact on backup windows and restore times.
