About a month ago, I helped one of my friends to upgrade from Windows 7 to Windows 10 using Microsoft’s free upgrade offer. Although Windows 10 was not automatically activated after the upgrade, we were able to activate Windows 10 after a brief chat with Microsoft support.

Before upgrading to Windows 10, my friend was using Mozilla Thunderbird but wanted to use the Mail app in Windows 10 instead of third-party tools. After adding his email account to Windows 10 Mail, he wanted to import a couple of ICS files into Windows 10 Calendar.

Calendar Restore app

Since Windows 10 Calendar doesn’t support importing ICS files, we had to use a third-party app called Calendar Restore to import ICS files into Calendar in Windows 10.

For those who don’t know, ICS or .ICS (iCalendar) is a format for calendar files supported by all popular email clients, including Microsoft Outlook and Mozilla Thunderbird. Even Google Calendar supports exporting and importing events in ICS files.

Coming back to Calendar Restore app, it’s a free app available in Windows Store designed to help Windows 10 users easily import all calendar events from ICS files to the Calendar app in Windows 10.

Features of Calendar Restore app

Supports iCalendar (.ICS) files

Supports ICS files with multiple events

Allows opening ICS files can be opened directly from email attachments

Associates .ICS files in File Explorer

Supports deleting imported events

Word events appear in local time

And more importantly, the app, according to the developer, doesn’t send any data to any servers.
