How can I ignore outlook contacts but use my Google contacts which also syncs with my phone etc.

Have just installed but contacts are coming from Outlook and I can’t find a way of changing the source to Google.

Hello Lenweed,
you can set up your Google contacts as a separate Contacts account.
Just go to Tools>Accounts section and add a New Account. Instead of automatic set up of a whole email account, go to Contacts>Google Contacts and set up this account.
You might want to also set up your Outlook mail account manually as IMAP if you want to avoid synchronization of Contacts and Calendar completely.

Regards,
Olivia
