Convert .PST/.OST File to MBOX file format – How to convert MS Outlook Data file to MBOX data file?

.PST and .OST files are for Outlook in Windows but they could not be more different. While the former is a personal file used for data archiving/backup and other operations, OST works with Outlook internally and automatically. There is no way to use OST files in any tasks manually.

However, if you have stranded and inaccessible OST files, you can retrieve the data back from them by converting it to the applicable format.
