explanation for non-techies**
Outlook for Mac is getting an update that will make it easier for users to manage their emails and data. This update introduces the ability to import PST files directly into Outlook for Mac. PST files are like digital filing cabinets for your emails, contacts, and calendar events, commonly used by Outlook on Windows. Previously, if you had a PST file and wanted to use it on a Mac, you had to go through a complicated process or use third-party software. Now, with this new feature, you can simply import these files directly into Outlook for Mac, making it much more convenient to access your data.
Additionally, the update will also support OLM files, which are the Mac equivalent of PST files. This means you can now both import and export OLM files, giving you more flexibility in managing your data. Think of OLM files as a suitcase for your emails and contacts when you're traveling between different devices or platforms. You can pack up your data in an OLM file, move it to another device, and unpack it there.
This change is particularly useful for organizations that use both Windows and Mac computers, as it simplifies the process of moving data between different systems. It's like having a universal plug adapter that works in any country, allowing you to connect and use your devices without hassle. This update will be available to users in various sectors, including government and defense, ensuring that everyone can benefit from this enhanced functionality.
