pop gmail, sync contact calendar

I want to use pop gmail but sync calendar/contact (imap). How can I mix this?

Hi Jackie,
you can just set these up separately.
In Tools > Accounts > New account choose Other to set up your POP gmail account.
Then go set up another New Account but choose Calendar > Google calendar.
Then in Accounts click your POP mail and in General tab > Default Folders > Calendar click Select and link your google calendar to it.

Best regards,
