mail forwarded from Gmail doesn’t arrive in Outlook.com

I have an IMAP Gmail account that I want to forward to Outlook.com.  I thought I’d followed all the set-up instructions for forwarding in Gmail and I even received an email in Outlook requesting confirmation of the forwarding request.  I clicked on the link to confirm and received a verification that Gmail was now able to forward to Outlook.  However, when I send myself a test message to the Gmail account from another email account I own, the message only goes to my Gmail Inbox and never gets forwarded to the Outlook.com Inbox.  Any help would be appreciated.  Thanks.
