How to Delete and Create a New OST File?

What is an OST File?

In Microsoft outlook, files are saved with the extension name (.ost) hence, .ost files can be called offline file folders for Microsoft outlook files.
These ost files make work easier. The ability to work without an internet connection or at your pace is incredibly important. The ost files allow you to synchronize your work when you come online with the exchange server so any changes made are noted.
Ost can also be called an offline storage table. It can be used to store a copy of your mailbox, even though the size of your ost file and mailbox won't correspond as it is not a representative of the latter. What is stored in your ost file also depends on your usage of an exchange/IMAP account?
