How can we improve Google Cloud Platform?

Allow SMTP to Office 365 (smtp.office365.com)

Your blocking of standard SMTP ports seems reasonable until you realize that outgoing e-mail can still be sent through G Suite mail servers and not Office 365 mail servers. My domain e-mail that I want to send mail through (low volume) is hosted at Office 365. I'm not going to move it to G Suite just for one little use. I don't see what, if anything, this has to do with IP reputation since smtp.office365.com requires login information. I was excited to use Google Compute Engine until I discovered this annoying fact. Now I'm going to have to use AWS or Softlayer.

        You can actually bypass that restriction using Microsoft Flow. You can set up a Flow that will send an email from a post request over https (port 443) so the outgoing port from the Google machine will not be SMTP. It is a really small change if you build you code correctly and you created your own sending method. Just send the call to the smtp sending request to a POST request to the url you got from your brand new Flow.

        Just remember to add auth to the flow. I use a key and compare it to a 50 letters value to make sure. It cannot be sniffed as the request is encrypted over SSL.

        Isn't this hugely anti-competition? Mailgun, SendGrid etc are all allowed but not Office 365? We're planning to launch a CRM integrated with our office365 mailboxes and this is a huge pain.

        I indeed just figured out that my Google Cloud VPS does not support my Office365 mailserver. What a b...****. I am not willing to move to a paid G Suite service where I already pay for my Office365 environment

        I agree with you Steven. What a petty way by Google to shut out Office 365 users? I had everything set up and was doing thru some last tests before going into production and didn't first understand why emails couldn't be sent. Now I will have to look at an Azure server instead. Too bad, I liked GCP, but this is not acceptable.
