I did a Microsoft Office repair last week. Now when I click on a .ics file, It opens up in the Windows 10 Calendar App instead of Microsoft Outlook. When I went to change the default settings, I didn't see any options for Outlook like I did in my email default programs.

 

How do I fix it? I have Microsoft Office 365 on the Monthly Channel Insider program and regular Windows 10.

Having the same issue. No way to assign Outlook as the default app.

I found my Outlook was 1809 vs 1909. Went to File | Office Account | Office Updates and updated. Now I can open .ics files and assign outlook as the default app.

@tward60  my windows is the latest Windows 10 update.

I just want everyone to know that this issue resolved without me knowing what happened. Perhaps it was the midmonth Office 365 update that fixed it, but all ics. files now default to my Microsoft 365 Outlook instead of my Microsoft mail app.

 

Again, I can't explain specifically how this got fixed if anyone else is experiencing the same problem

@B_Van_Spanje The same thing has started happening to me. I've run the Outlook updates and it's still not resolved it. It is really annoying you can set O365 as the default opener for ics files not the Calendar app.
