How to Forward Emails in Microsoft 365 Using Exchange Mail Flow Rules

by | Feb 20, 2026 | Exchange

Last Updated:

If your organization uses an operations mailbox like operations@magnetclicks.com, you may want to automatically route certain messages to the right person without manually checking and forwarding emails all day. A common example at MagnetClicks is routing content-related messages — like those mentioning “tutorials” or “functions” — directly to the editor at editor@magnetclicks.com.

The most reliable and professional way to do this in Microsoft 365 is with an Exchange Mail Flow Rule (also known as a Transport Rule). Unlike Outlook inbox rules, mail flow rules run at the server level. That means they still work even if nobody is signed into the mailbox.

In this guide, you’ll set up one simple automation:

  • Condition: operations@magnetclicks.com receives an email where the subject OR body contains tutorials or functions
  • Action: redirect (forward server-side) that email to editor@magnetclicks.com

You’ll get step-by-step instructions for both the Exchange Admin Center (GUI) and PowerShell, plus visual references for every step and a troubleshooting checklist.


Why Mail Flow Rules (Transport Rules) Are Better Than Inbox Rules

Microsoft 365 provides multiple ways to route messages, but not all methods are ideal for an operational mailbox.

  • Inbox rules (Outlook): Usually configured by a user and can be inconsistent across shared mailboxes.
  • Mailbox forwarding: Useful if you want to forward all messages, but it does not give you keyword-based logic.
  • Mail Flow rules: Centralized, auditable, and designed for conditional routing — perfect for keyword-based editorial automation.

If you’re building operational processes in Microsoft 365, transport rules align well with secure workflow practices like Multi-Factor Authentication and centralized controls.


Redirect vs Forward: Choose the Right Action

In Exchange rules, you’ll commonly see choices like Forward, Redirect, or Add recipients. For this scenario, Redirect is the best option.

  • Forward: The message looks like it was forwarded by operations@ (can clutter tracking and conversation threads).
  • Redirect: Preserves the original sender and headers, so the editor receives it more “natively.”

For editorial workflows and automation routing, Redirect keeps everything cleaner and reduces confusion.


What You Will Build

You will create a rule that triggers only when:

  • The message is addressed to operations@magnetclicks.com
  • The subject or body contains tutorials OR functions

Then it will:

  • Redirect the message to editor@magnetclicks.com
  • Optionally prevent loops with a simple exception

Method 1: Exchange Admin Center (GUI) — Visual Step-by-Step

Step 1: Open Exchange Admin Center

Sign in to the Exchange Admin Center using an admin role that can manage mail flow (Exchange Admin or Global Admin). Once inside, you should see the left navigation menu.

Step 2: Navigate to Mail Flow Rules

Exchange Admin Center navigation highlighting Mail flow and Rules
Go to Mail flow → Rules.

In the left menu, click Mail flow, then click Rules. This is where transport rules are created and prioritized.

Step 3: Create a New Rule

Click Add a rule and select Create a new rule. Use a naming convention that makes it easy to audit later (example: starts with “Ops – ”).

Step 4: Name the Rule

Suggested name:

Ops - Route Tutorials & Functions to Editor

Step 5: Add Condition #1 (Recipient is operations@)

Condition picker showing The recipient is option in a mail flow rule
Condition 1: The recipient is operations@magnetclicks.com

Set the first condition to target only messages going to the operations mailbox. This ensures the rule doesn’t trigger for unrelated mail.

Step 6: Add Condition #2 (Subject or body includes keywords)

Condition picker showing Subject or body includes any of these words in Exchange mail flow rule
Condition 2: Subject or body includes any of these words.

Add the keywords:

tutorials
functions

This condition behaves like OR for keywords: if the subject/body contains either word, the condition matches.

Step 7: Add the Action (Redirect to editor@)

Choose Redirect the message to and select editor@magnetclicks.com.

Recipient picker selecting editor@magnetclicks.com as the redirect target
Select editor@magnetclicks.com as the destination.

Step 8: Add Safety Controls (Stop processing + Anti-loop)

Add an exception to reduce the chance of accidental loops in future rule expansions:

  • Except if → the recipient is editor@magnetclicks.com
Exception section showing recipient is editor@magnetclicks.com to prevent loops
Add an exception for editor@magnetclicks.com (anti-loop protection).

Enable:

  • Stop processing more rules (prevents conflicts)
Checkbox or toggle for Stop processing more rules in Exchange mail flow rule
Enable Stop processing more rules to avoid rule conflicts.

Step 9: Save and Confirm Rule Priority

After saving, confirm the rule exists and appears in the correct order (top-to-bottom priority). If you later add more rules (e.g., for different keywords), put the most specific rules above more general ones.


Method 2: PowerShell (Exchange Online) — Visual Step-by-Step

PowerShell is best for documentation, repeatability, and change control. If you automate environments often, PowerShell is also the cleanest way to keep an audit trail.

Step 1: Connect to Exchange Online

PowerShell window showing Connect-ExchangeOnline command
Connect to Exchange Online using the ExchangeOnlineManagement module.
Connect-ExchangeOnline

Step 2: Create the Transport Rule

New-TransportRule -Name "Ops - Route Tutorials & Functions to Editor" `
-SentTo "operations@magnetclicks.com" `
-SubjectOrBodyContainsWords "tutorials","functions" `
-RedirectMessageTo "editor@magnetclicks.com"

Step 3: Add an Anti-Loop Exception

Set-TransportRule "Ops - Route Tutorials & Functions to Editor" `
-ExceptIfSentTo "editor@magnetclicks.com"

Step 4: Verify the Rule

Get-TransportRule "Ops - Route Tutorials & Functions to Editor" | fl

Testing the Rule (Visual Checklist)

Step 1: Send a Test Email That Matches

Test examples:

To: operations@magnetclicks.com
Subject: New tutorials draft ready for review

Body:
Please review these tutorials updates for publication.

Step 2: Confirm Delivery in editor@ Inbox

Because the rule uses Redirect, the message should look like it was delivered normally (not obviously “forwarded by operations@”).


How to Validate With Message Trace (When Users Say “It Didn’t Work”)

In Exchange Admin Center:

  • Go to Mail flowMessage trace
  • Search for the sender and recipient operations@magnetclicks.com
  • Open the message details and look for “rule applied” indicators

If your workflow depends on accurate email routing (like editorial submissions), it’s also worth keeping good security hygiene around mail accounts, including monitoring whether a mailbox address was ever leaked in breaches. You can learn more at Email Exposed in a Breach.


Common Mistakes and Quick Fixes

Mistake 1: Using “Forward” Instead of “Redirect”

Fix: Edit the rule and switch the action to Redirect so the editor receives clean headers and the original sender.

Mistake 2: Rule Not Triggering Due to Wrong Condition

Fix: Ensure the condition is set to Subject or body includes and that keywords are spelled correctly.

Mistake 3: Another Rule Runs First

Fix: Move your rule higher in priority and enable Stop processing more rules.

Mistake 4: Testing With the Wrong Mailbox

Fix: Confirm the test email is sent directly to operations@magnetclicks.com (not a distribution group or alias unless your rule targets that exact recipient).


Security Notes for Operational Mailboxes

Mail flow rules are powerful — and that power means they should be managed like any other change in your IT environment. As a best practice:

  • Limit who can create/modify transport rules
  • Document rule purpose and expected behavior
  • Review rules periodically as part of operational maintenance

Frequently Asked Questions

Does this work for shared mailboxes like operations@?

Yes. Mail flow rules run at the Exchange server level and apply regardless of whether a mailbox is shared or regular.

Why should I use Redirect instead of Forward?

Redirect preserves the original sender and headers, which keeps editorial workflows cleaner and more reliable.

Can I add more keywords later?

Yes. Edit the rule and add additional words to the “subject or body includes” keyword list. Keep your list focused to avoid false matches.

How do I prove the rule applied to a specific email?

Use Message trace in Exchange Admin Center and open the message details to see the transport rule actions.

What if emails contain “function” instead of “functions”?

Add both “function” and “functions” to the keyword list if you want both variants to match.
