Email Setup

Krav Maga Systems 21 Reputation points

Hi, I'm on a trial membership for MS 365 and have setup my general enquiries email for my business.

I've put in all the CNAME, TXT and other DNS requirements.

Two things:

  1. When I send an email to an another email in my network, it comes back saying it's not delivered. Seems I need to set something up on this end, but not sure what?
  2. When I log in, I want to have this email as the main email I'm using, but it has my other email as the main one for sending. I need to manually change this, but want to just have one email, rather than another one associated. I've tried deleting but it doesn't work.

Any help would be appreciated.

    So in essense, I've setup and I access it via link above. But when sending to it bounces back, even though those emails are setup on my web server.

    This is an expected behavior.

    After you verify your domain name ( on Office 365, you will could use this domain name for Exchange online mailbox.

    But, when you send emails to "", Exchange online will not send out this email to external of Exchange online, it will only search recipient within Exchange online.

    For your personal mail server, user may could send email with organization. But when external user sends emails to "", email will be sent to Exchange online and try to find recipient on Exchange online. Because this domain name is verified on Office 365.
