Nowadays it is pretty much impossible to exist without having an email address, let alone multiple ones.

But in order to send and receive emails efficiently, you will need a client that is fast and efficient and gets the job done.

One such candidate would be Microsoft Outlook, the de facto email client of the Microsoft Office Suite.

The difference between PST and OST files

As you may already know, Outlook stores all of the emails, contacts, calendars, and other such data locally on your PC as well.

This makes it so that the data can also be accessible even if you don’t have an Internet connection, or are somehow locked out of your email account.

Outlook stores this data as either  PST or an OST file, and the two formats are actually quite differnet.

These are the main differences between a PST and an OST file:

  • OST files are usable even when your Outlook is in online mode, while  PST is a Personal storage table used for locally stored data and files
  • OST files enable users the option to read, view, reply and compose emails even in offline mode, while PST files don’t

As you can see, having your data stored in an OST format seems to be far more beneficial, and that is why knowing how to convert a PST file into OST could be beneficial.
