I have an outlook account and a gmail account.
I want to forward all emails from Outlook to Gmail.
I have set up forwarding in Outlook (Settings -> Forwarding -> Enable forwarding is checked, my email is there)
Every time I log into outlook, a little notice now says "Email is being forwarded to XXX@Stuff .com". I have triple checked, and yes, my email address is spelled correctly.
But I have not ever received a forwarded email to my Gmail inbox.
I have checked my Gmail spam folder, and no, the emails are not being sent to spam.
I have tried directly sending an email from my outlook account to my Gmail - that works as expected.
