Hi @Sam18. Thanks for being part of GoDaddy Community! I had to do a little digging to understand what this error means. In most cases, this error will appear if you are sending email from an IP belonging to a high-security network or VPN that has been blocked intentionally by Google. If you are using such a connection, you'll want to contact your network admin so they can try to resolve the issue with Google. Otherwise, you may need to use a different connection when trying to send email. Hope that helps.

Dear JesseW


Thank you for taking your time to answer my question.


NONE of the email goes thru, not just google.... so it is not google issue for sure ( it must be Microsoft issue as I am paid user of Email Plus). Tried chat for support, I was always in que for 50 mins or over and by then timeout. Then I end up putting in community. Looks like I am not getting any support anywhere.

Can any Professional Email Plus (Microsoft 365) expert please help on it.

Can some please help. When I checked for help in Outlook it said following


550 5.7.708 Access denied, traffic not accepted from this IP

This error occurs when sending email from known, low reputation IP addresses that are typically used by new customers.

If you must send email from these IP addresses before you can purchase licenses, contact support to request an exception until you're able to purchase licenses.


GoDaddy should help me with this please

@Sam18. You can try using the following steps to request an unblock of the IP address you're using. If you know what the IP that is being blocked is, you can try requesting an unblock here.


If you're not sure what the IP is, you can use the process below to find it. It's a bit complicated but hopefully it will help. 


Find the IP used to send an email:

You will need to look at the message trace to see what IP address sent the email that is blocked. You should be able to do this from your primary/admin account by logging in and visiting First, you'll want to search for the address that received the bounceback using the screen below:




In the list of emails that appear, click on the one that was rejected (it should say "failed" under status) to view the message details. Use the screen that follows to find the IP.




Once you have the IP, look it up on the ARIN website to find out who the IP belongs to. 




Most often, the organization will list your ISP. If so, you can use the link I provided above to request an unblock. If it isn't your ISP, then you'll want to contact the admin for the organization listed to make sure they are not blocking email from the IP on purpose. If they aren't, then you can use the link I provided above to request an unblock. 


If you follow the process outlined above and the IP address is unblocked but you are still having trouble after 24 hours, you will need to connect with our customer care team so they can review the situation with our advanced support team. They may need to escalate the issue to Microsoft. If you do so, you'll want the following information/files available:

  • Your IP address
  • A copy of the original message that was rejected as a .eml or .msg file. 
  • A full copy of the bounceback text.

I had the same problem, and I solved it.  Allow me to explain what I did, maybe this will help.  I also use VPN (NordVPN), and it still works.


I already had Outlook 365 installed on my computer from my college days (i.e. I didn't need to download it from GoDaddy, which I believe contributed to this problem).  I had my Gmail, Yahoo, and school email accounts all tied into it.  After I signed up with GoDaddy, I set up another Outlook email account with my new GoDaddy email.  Kept getting that message whenever I would send an email from that account to Gmail, Yahoo, whatever. GoDaddy had me submit Microsoft delist requests, had me go see Google and Yahoo to fix it, etc. But they saw nothing wrong on their end. Webmail worked OK, but Outlook 365 didn't. I was about ready to request a full refund from GoDaddy. Then I discovered something.


VERY long story short, do this:

  • Open Outlook 365.
  • Click File.
  • Click Office Account in the left sidebar.

Now look at "User Information" at the top of the left column.  If that account is NOT your GoDaddy email account, that could very well be your problem.  If this is the case:

  • Temporarily shut off your VPN (yeah I know, but this is important and you'll be turning it back on in a minute).
  • Click on "Switch account." 
  • A pop-up window will appear.  Your GoDaddy email should be listed there along with your current user account.  Click on your GoDaddy email account and the window will close.

Now before turning your VPN back on, try sending some test emails.  When I did this, my emails started sending correctly from my GoDaddy account to all domains.  Once you can successfully do that, turn your VPN back on and try some more tests.  Should still work OK, it did for me.


Hoping for the best for all who need it!

Thanks, that solved my problem!
