How to fix outlook 2010 sync issues with folders on Gmail account?

I have a user that uses outlook 2010 and have their gmail account on outlook.

The user got a new pc, so I had to setup their gmail account again. I just used the automatic outlook setup that asks for username, email and password to set it up.

The mail downloads and the user can send mail, but the user gets sync error that mentions subscribed folders cannot sync.

I checked and all the folders is ticked for subscription. The user creates their own folders in outlook to organize their mail.

Where or what do I need to look at to solve the issue?
