Ringcentral.com blocked in edge

Question

We use ringcentral as our VOIP. Recently, something has changed and no one in our organization can access www.ringcentral.com.

We receive a message that says "This website is blocked by your organization." I am the owner and admin and not sure how to fix this.

Answer 1

Hi David,

This error occurs due to Edge policies configured on your system. Open the following link in Edge:

edge://policy/

See if there are any URLBlocklist policies that prevent access to www.ringcentral.com. If so, you need to remove the policy using the local group policy editor or the registry. If the system is part of an AD, the policies may need to be removed there.

The URL blocklist registry-based policies are located in the following branches:

HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Edge\URLBlocklist

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge\URLBlocklist

Answer 2

The message “This website is blocked by your organization” in Microsoft Edge is caused by an organizational policy or filtering solution, not by Edge itself. As owner/admin, the fix is to locate and change the policy or filter that blocks ringcentral.com.

Work through these checks in order:

1. Check if Edge Web Content Filtering is blocking the site
   1. On an affected PC, open Edge and go to edge://settings/privacy.
   2. Under Privacy, search, and services > Security, look for Web content filtering.
   3. If Web content filtering is enabled and managed by your organization, sign in to the Edge management service (the admin portal where Edge policies are configured).
   4. In the Edge management service, open Web content filtering and review the policy assigned to your users/devices.
   5. Check the blocked categories and custom block lists to see if ringcentral.com (or its category, such as “VoIP”, “Communication”, or similar) is blocked.
   6. If it is blocked, either:
      • Add ringcentral.com to the allow list, or
      • Adjust the category rules so that the category containing ringcentral.com is allowed.
   7. Be aware that policy changes can take up to 90 minutes to apply to user devices.
2. If users see a block page with a “Request access” option If Web Content Filtering is configured via the Edge management service with user requests enabled:
   1. Ask a user to browse to ringcentral.com and, on the block page, select Request access.
   2. Have them enter a justification and send the request.
   3. As admin, go to the Edge management service → Web content filtering → Requested sites.
   4. Under Active requests, select the domain for ringcentral.com.
   5. Review the request and set Allow site for all users in this configuration policy? to allow the site.
   6. Save the change; the domain will be added to the allow list for that policy.
3. Check for other organizational filters If Web Content Filtering in Edge is not enabled or not blocking the site, then another organizational control is responsible, such as:
   • A third‑party web filter or security agent (for example, Lightspeed, Zscaler, Cisco Umbrella, etc.).
   • A firewall or secure web gateway blocking the domain.
   In that case, sign in to the admin console of your web filter or firewall and:
   1. Search for ringcentral.com in block/deny lists or URL categories.
   2. Remove it from any explicit block list or create an allow rule for ringcentral.com.
   3. Apply or publish the policy and test again from a client.
4. Confirm no SmartScreen false positive If the block page explicitly mentions Microsoft Defender SmartScreen (for example, “reported as unsafe”), then:
   1. Verify that the page is indeed safe and that the block is unexpected.
   2. On the SmartScreen warning page, select More information and then Report that this site doesn't contain (malware/phishing) threats.
   3. Complete the submission so Microsoft can re‑evaluate the site.
   4. Alternatively, the site owner can use the WDSI file submission portal to report the issue.

Once the responsible policy (Edge Web Content Filtering, a third‑party filter, or firewall rule) is updated to allow ringcentral.com, users should be able to access the site again after policy propagation.
