User Query: I have a lot of ICS files from my old email service. They contain my calendar appointments and meetings. I want to open these ICS files in Outlook. Is there any simple method available to convert ICS to PST without losing calendar data?
Summary: ICS files are used to store calendar data like meetings, events, and reminders. Many apps, including Google Calendar and Apple Calendar, use this format. But if you want to use Outlook, these ICS files won’t open directly as PST is Outlook’s default format. So, if you want to import ICS files into Outlook, you’ll need to convert them to PST. In this blog, we’ll show you both a manual and a professional DRS ICS Converter Tool to convert ICS to Outlook calendar. In addition, both method gives you a quick, reliable, and 100% accurate conversion.
Why Convert ICS File to PST?
PST files directly allow you to open all your emails in Outlook without needing any extra steps. Let’s explore all the benefits of using the PST file as compared to the ICS format, including:
- Outlook uses PST to store emails, calendars, and more.
- Direct compatibility with Microsoft Outlook.
