Certain IP address unable to access sharepoint online

Laura Huffman 0 Reputation points

I have a client that has restricted access to his SharePoint Online tenant based on IP address. Everyone on the organization's network can access SharePoint Online without any issues. I am trying to access the SharePoint Online tenant remotely and my IP address has been added to the access control settings in the SPO admin center. Up until 2-3 weeks ago, I was able to access the tenant without any issues. Now I am only able to access the tenant sporadically. Most of the time I receive the Access Denied due to organizational policies screen. I am able to always authenticate to www.office.com, I am only having issues connecting to SharePoint Online. I am at a loss and would like to know what settings I need to be checking to troubleshoot the issue.

    Hi @Laura Huffman ,

    We understand your requirement to use the Network Location feature to give permission for specific IPs.

    We try to test this feature and we couldn't repro the same issue on our side.

    Please try follow method to see whether the issue still exists.

    • Remove the IP address and adding them back the next day
    • Turning the feature Off for a few days and turning it back on.
    • Reduced the number of IP address allowed thinking there was a limit.

    If the way above not working, we think the issue should be checked and fixed from the backend.

    As forum support we may not have enough permission and resource to directly check the environment on your side. But the support team with higher permission level could help you with this issue remotely.

    Please follow steps in this article and try to create a support ticket to contact Online Support.

    Thanks for your understanding and cooperation! Hope you are keeping safe and well.
