How to Fix Allow a Brother Printer Through the Firewall in Microsoft 365

To fix allow a brother printer through the firewall in Microsoft 365, first identify the correct account, file, device, or service context. The steps below isolate the cause and apply a result you can verify.

Confirm the Account, Product, and Expected Result

Start by confirming whether the symptom affects one file, one device, one account, or the service itself. That distinction determines whether the next action belongs in the desktop app, the web portal, or an administrator console.

Quick Supported Workflow

First, open Control Panel → System and Security → Windows Defender Firewall. Next, select Advanced settings on the left, and verify the final state before changing any backup or secondary account.

Why This Can Happen

• The wrong personal, work, school, billing, or administrator account is selected
• A license, permission, connection, file rule, or local setting does not match the requested action
• Cached credentials or an incomplete synchronization or activation state hides the current server status
• The Microsoft service or application requires a more specific control than a generic restart

Practical Checks That Prevent a Repeat

• Record which account, app, and file owns the workflow
• Keep a verified backup before removing access, changing ownership, or replacing a local file

• Save confirmation numbers, dates, and screenshots of the final settings when they affect billing, security, or permissions

Frequently Asked Questions

Why should I open Control Panel → System and Security → Windows Defender Firewall?

Open Control Panel → System and Security → Windows Defender Firewall. Use the account that owns the file, subscription, tenant, or setting. Personal and work accounts can expose different controls.

What should I check after I select Advanced settings on the left?

A small test confirms the correct account, permissions, and destination before the action affects a larger set of files or users. Confirm the account type, product version, ownership, and permissions before assuming the control is unavailable.

What result should I expect after I open the Windows Security app and select Firewall & network protection?

Keep the original file, confirmation messages, relevant account details, and any existing case or transaction number needed to reverse or verify the action. Keep the relevant backup or confirmation until you have checked the result.
