.PST and .OST Storage Files

What are .PST and .OST Files

PST Files

Since Outlook 2016, PST is not anymore use for emails and Konto informations.

OST Files

OST files contain only your Outlook settings but not your emails. If all your emails are stored on the mail server, this configuration is called IMAP. Microsoft created a different version of IMAP called MAPI.

OST files are still network sensitive but will never become as big as PST files because they only contain settings but no actual mails.

.OST Storage Location

After starting your email client, the appropriate file is created. OST files are stored in C:\Users\<USERNAME>\AppData\Local\Outlook and will remain local.
