Before you start

Ensure you know who your organization's tenant administrator is, as modifying security policies requires specific elevated permissions.

Solution 1Recommended

Verify Security or Exchange Administrator Permissions

Confirm that your account has the necessary administrative roles assigned to view and modify delivery policies.

Advanced Delivery options in Microsoft 365 are strictly controlled by role-based access. If your account lacks the necessary permissions, the option will be hidden from the menu, and direct links will produce data loading errors.

1
Check current role assignments

Sign in to the Microsoft 365 admin center and navigate to Role assignments. Verify if your account holds the Security Administrator or Exchange Administrator role.

2
Request administrative access

If you do not have the required roles, contact your organization's tenant administrator to request the necessary Security Administrator or Exchange Administrator permissions.

3
Wait for propagation

Once the role is assigned, allow some time for the permission changes to propagate through the system, then attempt to access the Advanced Delivery options again.

Verify Security or Exchange Administrator Permissions
Permission Delays: It can sometimes take up to a few hours for newly assigned administrative roles to fully sync and grant access to the Defender portal.

Frequently Asked Questions

Why is the Advanced Delivery option missing from my portal?

The most common reason the Advanced Delivery option is missing is that your user account has not been assigned the Security Administrator or Exchange Administrator roles required to view and edit these policies.

Where should the Advanced Delivery options be located?

When you have the correct permissions, you can find the settings in the Microsoft 365 Defender portal by navigating to Email & collaboration > Policies & rules > Threat policies > Advanced delivery.

Can I configure Advanced Delivery rules without admin rights?

No. Advanced Delivery settings control organization-wide threat policies, such as phishing simulations and SecOps mailboxes, which strictly require administrative privileges to configure.

How do I clear my cache to fix Microsoft 365 loading errors?

In most modern browsers, you can press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac) to open the clear browsing data menu. Select 'Cached images and files' and 'Cookies', then clear the data and restart your browser.
