My IP is Blocked from Microsoft & Azure Services – Request for Delisting

Question

My IP is Blocked from Microsoft & Azure Services – Request for Delisting

Phil 0

Hello,

My public IP address appears to be blocked by Microsoft’s Azure infrastructure. I’m unable to access multiple Microsoft-hosted services including:

https://portal.azure.com
https://onedrive.live.com
https://office.live.com
And BT Email, which I believe may be utilizing Microsoft/Azure infrastructure

The error message displayed is: “The request is blocked.”

I have attached the error request_blocked.png this is standard across these services (I even have to use a VPN to post here)

I have also attached a traceroute trace.txt

This affects all devices on my network—yet access is restored immediately when switching to a different IP (e.g., via mobile hotspot or VPN).

I have verified the following:

My ISP confirms there are no restrictions or blocks on their side.
My IP is not blacklisted on any major public IP reputation tools (MXToolbox, HetrixTools, etc.).
This issue is reproducible across multiple Microsoft domains and services.
Microsoft’s standard support and community forums have not resolved the issue.

I attempted to contact Microsoft via delist@microsoft.com with no luck

Please advise how I can proceed to have my IP restored for access, or whether there is a dedicated escalation path.

Thank you

Hello Phil

I can understand how frustrating it must be to have your IP address blocked from accessing Microsoft Azure services and other Microsoft-hosted sites. Here are some steps you can try to resolve this issue:

Check for Temporary Blocks: Sometimes IP blocks can be temporary and related to connection volumes or security measures. If you've recently had high network traffic from your IP, the block might be lifted automatically after a while.

Investigate Any Misuse: Ensure that your IP address hasn’t been used for any spam or abusive activities. If your IP is dynamically assigned by your ISP, someone else may have previously used the IP for malicious purposes.

Refer: External senders - Use the delist portal to remove yourself from the blocked senders list and address 5.7.511 Access denied errors

I hope these suggestions will help you regain access! If you still encounter issues, please let me know, and we can look into it further.

Also, could you please clarify:

Have you received any specific error codes apart from “The request is blocked”?

Are you using a static or dynamic IP address?

Could you please share the Support ticket number on Private messages.

Hope this helps and let me know if you need more assistance!

If the above is unclear or you are unsure about something, please add a comment below.

Hi sorry for the delay I have been away for a few days.

Thank you for the suggestions but unfortunately none have resolved the issue.

The block isn't temporary as this has now been over a month
There has been no IP misuse, I only use Azure for work as a software engineer so will sometimes spawn accounts to check Office365 SSO, that is about it

I have tried the delisting service numerous times but it does not resolve the issue. The service seems to be for email spam only.

I have also directly emailed delist@microsoft.com with no luick on resolving the issue.

The screenshot in the original post shows the error I recieve, a generic request is blocked then Ref A, B, C

My IP is dynamic but does not change as my ISP does not reallocate them often (can be over a year) so its pretty much static at this point

I haven't recieved a support ticket number.

Thank you for your response.

Does Azure not have a delist service at all? It seems extreme that they can block an IP for many vital services, it essentially makes even windows unusable because so many of its backend systems use the same service, which is extremely annoying considering the cost.
