PC desktop Outlook calendar not syncing with iPhone Outlook app Calendar (university email)

[apip28]

I am using Outlook on my PC laptop. The only calendar meetings or appointments that populate over to my iPhone Outlook app are those that other people send which I accept. If I create my own appointment or meeting, it only shows on my desktop outlook. I have a go.edu email address through my university, which is also a Google email. Having a hard time getting a workflow going. I need to learn how to use Outlook as everyone uses it in my industry. I have been functioning with just Gmail in a browser.
