I have a private Gmail and a Google Apps account, how can I synch both with Outlook?
It doesn't matter if you have a Gmail account and a Google Apps account. You can configure both of them. First access each of the accounts and go to Settings and enable IMAP and POP3 then switch to Outlook. Go to Tools > Account settings and add each account then use the information on Google Support to properly assign the servers, IMAP ports and security.
