Automation Get Email is not sending to Custom Email of specific domain

Question:
Why is Wix/EditorX automation get email not sending emails to a specific domain?

Product:
Editor X

What are you trying to achieve:
Get email notification sent to my business email address or any email address on our domain (@fgamd.com) that is managed by wix.

What have you already tried:
Testing different email addresses and testing the business email address with “send email”, which works.

Additional information:
I created a automation to get email notification to our business email address and it is not sending. It use to work before the email address (.onmicrosoft) was updated to the current domain (@fgamd.com) that is managed by Wix. It will still send email to gmail accounts and if I use the send email automation it can send to our business address.

For future reference. It turns out after domain migration to new Microsoft tenant, the Exchange server is now flagging these Wix emails as malware. It didn’t before.
