Not allowing me to retrieve calendars

[kathyrainsbury1]

Hi, Can you tell me how to solve this - I initially managed to retrieve the calendar and authorise the app. When I then tried to sync, I wasn't able to and it get saying that google calendar not available. I reloaded it all, but now it says that it won't work if I don't allow it access to my google Calendar. However, when I try and retrieve the calendars again, it doesn't come up with the google accounts to choose from & I keep going back to not allowing access/ permission.
Thanks for your input.

I have now managed to fix the issue. However, many of my outlook appointments haven't transferred onto my Google calendar? Not sure why this is?
