Thank you, Diane. I was doing it incorrectly, but there doesn't seem to be a way to add it directly to Outlook. This is my daughter's school schedule. When I click the link on their website, it gives me a choice of "Open with Outlook" or download. If I click "Open with Outlook", only the first event is copied (New Years Day as an Administrative Holiday) & it's copied to my default calendar.
If I download it & open it with Outlook, the same thing happens. I guess the link will download an .ics file to my computer, but doesn't give me options other than Open.
I did solve it indirectly by doing this:
To import into iPhone:
1. Tap the email message that has the attached ICS calendar file.
2. Tap the ICS file name in the email message window. A list of events appears.
3. Tap "Add All", and then "tap the calendar" to which you want to add the ICS calendar file events, and then tap "Done".
4. Press the "Home" button. Tap the "Calendar" icon on the iPhone’s home screen to access your newly imported ICS calendar events.
5. Then you can sync with Outlook 2016
However, I just tried it with Outlook 2016. I downloaded the .ics file to the computer with Outlook 2016. When I chose "Open", it added all the events to a new untitled calendar in Outlook 2016. It gave me a choice of calendars, so it works.
It doesn't work with Outlook 2003 & I'm not sure why not. Outlook 2003 doesn't give me any options & doesn't add anything but the first event.
