Why Users Want to Export Calendar from Outlook to ICS?

ICS files open on almost any calendar app, so your events stay accessible everywhere.
Backing up your calendar as an ICS protects your schedule if the OST file gets corrupted.
Switching from Exchange Server to Google Workspace makes ICS the easiest sharing format around.
Offline OST files become useless without an Exchange connection, so ICS keeps things accessible.
Sharing your calendar with Mac or iPhone users is much simpler using a standard ICS file.
Some organizations archive old employee calendars in ICS format for record-keeping and compliance purposes.
Recurring meetings and appointments transfer more cleanly when saved in a universally supported ICS format.

Free Methods to Export Outlook Calendar to ICS

There are two manual methods. The first method works on Outlook 2016, 2019, 2021, and Microsoft 365. The second method is effective if you’re using the browser-based version of Outlook.

Method 1: Import Outlook Calendar to ICS via Desktop App

Firstly, open Outlook and go to the Calendar section.
Then, select the specific calendar to export.
After that, go to File > Save Calendar.
In the Save As window, choose a destination for the file.
Under Save as type, select iCalendar Format (*.ics).
If you want to narrow down the date range or control which details are included, click More Options before saving.
Hit OK, then Save.

Method 2: Convert Outlook Calendar to ICS

Firstly, go to Outlook.com and sign in.
Further, open the Calendar section from the left sidebar.
Thereafter, select the calendar you want to share or export.
Click Share, then choose Publish Calendar.
Set the visibility to Can view all details and copy the ICS link that appears.
You can paste this link directly into another calendar app or open it in your browser.

Limitations

If you have multiple calendars, you’ll need to repeat the process again and again.
There’s no option to export multiple calendars or entire mailbox data in one go.
This method only works if you have the desktop version of Outlook installed and configured.
Instead of a file, you get a link. You must manually open or import it into another app.
You cannot selectively export specific events or apply advanced filters.

Getting your Outlook calendar into ICS format is not that complicated once you know the steps. If you only have a few events or a small calendar, the manual method works fine.
