Fix Cannot Import ICS Files in New Outlook for Mac
Question details
The user is unable to import ICS calendar files into the new Outlook for Mac, though the feature continues to work as expected in the legacy version of the application.
- Product
- Outlook for Mac
- Device & OS
- macOS
- Scenario
- Attempting to import an ICS calendar file into the newly updated Outlook interface on a MacBook Pro.
- Observed behavior
- The ICS file fails to import into the new Outlook for Mac, whereas it successfully imports when the user switches back to the legacy Outlook version.
Ensure your Outlook app and macOS are updated to the latest versions. You may also temporarily switch back to legacy Outlook to import urgent calendar invites while troubleshooting.
Create a New Outlook Profile
Creating a fresh Outlook profile can often resolve underlying corruption or syncing issues that prevent ICS files from importing.
Sometimes the local Outlook identity becomes corrupted during the transition to the new interface. Creating a clean profile forces Outlook to build a new local database.
Open the Finder, navigate to the Applications folder, right-click Microsoft Outlook, and select 'Show Package Contents'. Go to Contents > SharedSupport, and double-click 'Outlook Profile Manager'.
Click the '+' (Create a new profile) button, enter a recognizable name for the new profile, and press Return.
Select the newly created profile, click the gear icon at the bottom, and choose 'Set as Default'. Restart Outlook, set up your account, and try importing the ICS file again.
Contact Dedicated Outlook for Mac Support
If profile recreation does not work, report the bug directly to the dedicated Outlook for Mac support team from within the app.

Frequently Asked Questions
Why do ICS files open perfectly in legacy Outlook but not the new Outlook for Mac?
The new Outlook for Mac is built on a completely different synchronization technology framework. Some features, including local ICS file imports, might experience bugs or have limited functionality compared to the legacy version while Microsoft continues its development.
How do I temporarily switch back to legacy Outlook for Mac to import my files?
You can switch back to the legacy Outlook by opening the 'Outlook' menu at the top of your Mac screen and unchecking the 'New Outlook' option. The app will restart in the classic interface where you can successfully import your ICS files.
Are my existing calendar events lost if I create a new Outlook profile?
No, creating a new profile does not delete your old data. Your existing events are securely tied to your email account (such as Exchange or Microsoft 365) or your old local profile, which you can switch back to at any time using the Outlook Profile Manager.
