Outlook email IMAP issues

I've followed the instructions to bring my domain emails to my outlook application.  I can send and receive to other accounts on my domain, and can receive from any other email, but keep getting return to sender messages when sending outside of our domain.  


SMTP error from remote mail server after end of data:

    550-5.7.26 This mail is unauthenticated, which poses a security risk to the

    550-5.7.26 sender and Gmail users, and has been blocked. The sender must

    550-5.7.26 authenticate with at least one of SPF or DKIM. For this message,

    550-5.7.26 DKIM checks did not pass and SPF check for [

    550-5.7.26 m] did not pass with ip"

Can you go ahead and try once more? I have updated the TXT SPF record for your domain which should allow it to begin working properly.
