The transfer of MBOX to PST format is possible with a variety of MBOX to PST Converter Tools available on the internet. I also recommend SysInspire, which is the most popular and cost-effective email conversion application. It can convert all emails and other data from MBOX files to Outlook PST files in a matter of seconds. This Tool saves PST data to new and existing PST files, as well as corrupted and non-corrupted MBOX files. I also recommend trying out the tool's free demo version before purchasing the complete premium version.
