AxBlaze OST to PST Converter

AxBlaze OST Converter is an advanced software solution developed to convert the Exchange cache and IMAP OST files to PST, MBOX, EML, EMLX, PDF, NSF, TGZ, CSV, VCF, ICS, MSG, and HTML file formats by maintaining all the Meta properties such as to, cc, bcc, sent/receive date and time, attachments, etc.

The software also migrates the OST data to the mail servers (Gmail, Office 365, and Exchange server). For OST contacts and calendars, it provides a separate conversion option by which you can export OST contacts to VCF/CSV and calendars to ICS/CSV formats.
The file size of the OST converter is just 27588 KB which is easy to download. The application has an install and uninstalls facility that makes this utility flexible. That is a Windows-based program that supports all Windows OS versions. The free demo version is available to test the email conversion utility, but it will export only the first 30 items from each folder of the OST files.
