Question details

Users need to resolve DNS errors that are preventing all users and devices from accessing SharePoint or OneDrive for Business sites within a Microsoft 365 tenant domain.

Product: SharePoint and OneDrive for Business
Device & OS: not provided
Scenario: A tenant-wide access failure where DNS errors block users from reaching their cloud storage and collaboration sites.
Observed behavior: All users across all devices experience DNS resolution errors when attempting to access SharePoint or OneDrive for Business URLs.

Before you start

Ensure you have Microsoft 365 administrator privileges, as resolving tenant-wide DNS issues requires access to the Microsoft 365 admin center.

Solution 1Recommended

Check Subscription Status and Test Alternative Networks

Since the issue affects all users, the most common cause is an expired subscription or a widespread network routing problem that needs administrator intervention.

When DNS errors affect all devices accessing a Microsoft 365 tenant, the problem usually originates from the backend domain configuration or an inactive billing status.

Access Microsoft 365 Admin Center

Navigate to Billing

In the left-hand menu, go to 'Billing' and select 'Your Products' to view all active and expired subscriptions.

Check Subscription Status

Ensure the Microsoft 365 subscription is active. If the subscription is expired or disabled, renew or reactivate it to restore DNS routing.

Test Another Network

If the subscription is active, connect a device to a different network (such as a mobile hotspot) to rule out local ISP DNS caching issues.

Open a Service Request

If the error persists across different networks, open a service request in the Microsoft 365 admin center to have Microsoft investigate the tenant's DNS configuration.

Admin Access Required: Only users with Microsoft 365 global admin or billing admin roles can view subscription details or open official support tickets with Microsoft.

Frequently Asked Questions

Why am I getting a DNS error only on SharePoint and OneDrive?

DNS errors specific to Microsoft 365 services usually happen if your tenant domain is suspended due to billing issues, or if there is an ongoing Microsoft service outage disrupting their domain name servers.

Can a standard user fix tenant-wide DNS errors?

No. If the issue affects all users and devices on the tenant, it requires a Microsoft 365 administrator to check the billing status or contact Microsoft support.

How long does it take for DNS to propagate after reactivating a subscription?

Once an expired Microsoft 365 subscription is reactivated, it can take anywhere from a few minutes to a few hours for the DNS records to fully propagate and restore access to SharePoint and OneDrive sites.
