Prerequisites
- A Mermail mailbox address.
- Access to Outlook settings or rules.
- Administrator approval if your Microsoft 365 organization blocks external forwarding.
Forward selected messages with a rule
1
Open Outlook rules
In new Outlook, Outlook on the web, or Outlook.com, open Settings → Mail → Rules.
2
Create a rule
Click Add new rule and enter a clear name such as
Forward support mail to Mermail.3
Choose conditions
Add conditions for the recipient address, sender, subject, or another supported field. Add exceptions for sensitive messages when needed.
4
Choose the forwarding action
Select Redirect to when you want the message to retain the original sender, then enter the Mermail address.
5
Save and test
Save the rule and send a new matching message. Confirm that it appears in Mermail.
A forwarded message appears to come from your Outlook address. A redirected message appears to come from the original sender. Redirecting is usually a better fit for a mailbox workflow because it preserves sender identity.
Forward all messages
In new Outlook or Outlook on the web:1
Open forwarding settings
Open Settings → Mail → Forwarding.
2
Enable forwarding
Turn on Enable forwarding and enter the Mermail mailbox address.
3
Keep an Outlook copy
Select Keep a copy of forwarded messages if you want the original provider to retain each message.
4
Save
Save the setting and test with a new incoming message.
Test the setup
Send one message that matches the rule and one that does not. Check the Mermail mailbox and the Outlook junk folder. Confirm that only the intended message reaches Mermail.Stop forwarding
- Delete or disable the inbox rule under Mail → Rules.
- For account-wide forwarding, return to Mail → Forwarding, disable forwarding, and save.
Human takeover
If you reply to a forwarded thread directly in Outlook, Mermail treats the entire thread as human-managed and permanently stops AI processing for it.Troubleshooting
See Microsoft’s current guides for automatic forwarding and rule-based forwarding or redirecting.
