Problems sending to hotmail account

I am having problems sending to a hotmail account. I have dmarc, etc set up and working and have no problems sending to anywhere else (gmail etc), but when I send to a user on hotmail, I get the following error: 

(550 Cannot process address)

Information about your message:
Subject: Test Message
GroupWise Message Id: 5F1ED9BD.D14:6:31696
Message log tag: 2203118
Number of send attempts: 1

Time of initial send attempt: 07-27-20 14:42:25

Possibly truncated original message follows:
Received: from Domain-MTA by rene.northern-connection.co.uk
with Novell_GroupWise; Mon, 27 Jul 2020 14:42:25 0100

Anyone have any ideas what is causing this issue. I am not blacklisted, and can ping hotmail from the mail server. 

Also, I can send email to the particular hotmail account from gmail with no issues.

Regards

ChasR.

  • Hi   

    You'll need to take a look at the SMG logs too.

    Does it mean my ip address is on the block list by microsoft? If so, any ideas how to undo this ?

    Thanks for your pointers with this problem,

     

    Regards

    ChasR.

  • I have found the appropriate form to request removal of the ip address blacklist from microsoft  hotmail. For anyone in the same position, here is the link:
