I was able to export my Outlook calendar events to my Google calendar using This YouTube video. This will export your Outlook calendar but not actually sync the two.

Anyway, this worked with my Google calendar on my PC, but my Outlook events don't appear on the Google calendar on my phone.

Is there a way to export my Outlook calendar to my Google calendar on my phone?

As far as I know, once the Outlook events have been shared/imported to your Google account, they (obviously) should sync with any other devices that are connected to that Google account.

Android or iOS phone?

Using the GMail app on your phone, thru a browser, or some other app?

If you manually add a new event to your Google Calendar on your PC does it sync to your phone?

Andriod

I'm using the Google Calendar app

Yes, it does. Thank you for your reply.

Examined the events in your Google Calendar that were from your Outlook share/import? Is there anything different about them compared to an event that you created manually directly in your Google Calendar?

If not, them I am sorry, but I don't know of any reason why it would fail to sync events, that are in your Google calendar, just because they came from an Outlook Calendar share/import.
