Administrative prohibition error

administrative prohibition error

I am getting this error as well (Error on outgoing settings: Sending email from SMTP server failed: 550 Administrative prohibition). Solution · The sender's email address or domain has triggered a Blocked Senders Policy, or there's a SPF hard rejection. · The Block Sender Policy. The message means that for some reason the system administrator on one end or another refused to allow the message to be transmitted.

Administrative prohibition error - me!

If you receive an email error: Administrative prohibition or 550 Administrative prohibition:

This means that you cannot send email to that server right now. You can email [email protected] to find out how long it will be before we enable sending to that server again. This usually means that either we have a security issue  or one of our clients are attacking someone at that server so we have administratively blocked all traffic there.

 

If someone is sending you an email and they receive an Administrative prohibition error or 550 Administrative prohibition:

This means that they, the sending ISP is broken or probably  maybe has a security issue and that they, the sending email service have administratively blocked sending to Nkosi as they may be attacking us or for some other reason has decided to block us. The Sender has to contact their ISP and ask when they will be able to lift the administrative prohibition or find out why they cannot send email.

A error message such as "The mail server responded ADMINISTRATIVE PROHIBITION. Please verify that your email address is correct in your Mail preferences and try again." or "550 Administrative prohibition" is due to the SMTP server blocking your attempt to send a message. Some typical causes:

  • The domain used by your SMTP server is on one or more real time black lists (RBLs) and the recipients mail server is rejecting the message because a lot of spammers send mail from that domain. Try sending from another accounts SMTP server.
  • The recipient is in a domain that is on one or more real time black lists (RBLs). Your email provider won't let you send the message since they suspect you're either replying to spam or have been compromised or hacked. Try sending using a different SMTP server.
  • The SMTP server can't authenticate you. See 5.7.1_Unable_to_relay . If you're sending mail from a Gmail account try adding the Gmail SMTP server and using it.
  • You're sending from a SMTP server with a dynamic IP address. Some ISPs mail servers reject messages sent from dynamic IP addresses. This might occur if you are using a local SMTP server (perhaps a built-in SMTP server in a webmail add-on or Free SMTP Server) and have a dynamic IP address due to using PPP, DHCP, PPPoA , PPPoE or a wireless connection. Try sending the message using your ISPs SMTP server.

I forgot to mention that the reason I began having this trouble is when I upgraded a few days ago to Outlook 2016. That is when one of my emails got the hick-up above.

Hi Debra,

Based on the error, it’s an Outlook Non-Delivery Report (NDR) not a system NDR.

To check if there are any policies in Outlook client disable the sending, I suggest you try the following points:
1.Update Outlook client to the latest version.
2.Re-create a new mail profile.
3.If you have subscribed to Office 365 Business plan, type the address manually and send an email to it in Outlook Web App.
4.Open Outlook in Safe Mode by pressing the ‘Windows + R’ key on the keyboard->type in ‘Outlook /safe’-> hit OK in the Run open box (There is a space between Outlook and /)

In addition, if your account is @gmail.com or @live.com, since our forum focuses on Office 365 Business Online services, we recommend you turn to Outlook client forum for directly assistance.

Thanks,
Zoey
