Spending hours organizing and reading emails is part of the daily routine for many of us. Like most users, we get comfortable with our preferred email platforms. In my case, I’ve been using Microsoft Outlook with an OST file setup for quite a while. It worked perfectly for managing my offline mailbox data. But recently, things changed.

Due to a major system update and a shift in our work environment, I needed to access my old OST files on a Mac system, but that wasn’t straightforward. OST files are not natively supported by Outlook for Mac. We soon realized that we needed to convert these OST files into PST format to make them usable across both Windows and macOS.

Our IT team explained the challenge: OST files are bound to the profile they were created with and can’t be opened directly once disconnected.
