Guidance sought! replaced SG115 with XG135 on 18.x 2 days ago. Using Outlook from O365 licensing with Gmail and G-Suite. Can receive into OLK, but SMTP send is blocked. Send/receive from Gmail web client ok. Found a lot of articles re exceptions to add for O365, but nothing for Gmail or Gsuite. Added exception for smtp.gmail.com but it didn't help. Tech support hasn't responded - can anyone guide me, please?
thx
Ben
