“request parameter validation failed” error when updating Calendar (gmail)
Started a few day ago. Haven’t made any changes to my email client or to gmail.

Hi,
Can you please check your google account security settings if “allow less secure app” is enabled?

I just enabled 2-Step Verification and apparently can’t view or change this setting.
I have removed my 2-step verification, and allowed less secure app’s. But, I’m worried that it will synch and call up the less complete gmail calendar info. How do I retrieve my previous calendar entries that weren’t in gmail calendar?
Does anyone have any advice on this? Should I close the app and see if the calendar entries return? Where did they go?
