Hello,
I recently created a new business email address using outlook....However my email does not end with outlook.com
It uses my business domain.
There are few instances where my emails are getting rejected by certain recipients. It's very important this gets resolved fast because this email is used for business.
Can you please help?
Thank you,
Irina

Hi, I'm having a similar issue, and it seems to be related to my IP Reputation @ Cisco Talon.
iphmx.com is part of this system... Although my SPF/DKIM/DMARC is setup properly and my IP Reputation is Neutral + no blacklist, I'm still getting this error. Anyone encounter similar problem and how to fix?
Cheers

Does that mean you configure a new account in Outlook app to connect to your business email account? Who is hosting the mailbox?
Is there anything I can do to fix this?

What does the bounce mail notification say? What is your domain name?
