Send Outlook emails to Obsidian automatically with rules

If you've tried to get Outlook mail into Obsidian before, you've probably met the usual problem. Most Outlook tools depend on classic Outlook for Windows and drag and drop, so they fall apart on new Outlook, the web version or your phone. And at work, IT often locks down add-ins anyway.

A rule that forwards to an address sidesteps all of that. There's no Outlook add-in and no connection to your mailbox. Automate it if your IT allows it; forward by hand if it doesn't.

Quick answer: Forward works, Redirect doesn't

We accept an email only when its From address is you: your account email or a verified sender. Outlook's two similar-sounding actions behave differently here.

Outlook also offers forwarding as an attachment. We haven't confirmed how that comes through, so stick with "Forward to".

Before you start

If you haven't set up Email2Obsidian yet, it's three steps and about two minutes:

1. Sign up free (no credit card) to get your ingest address.
2. In Obsidian, open Settings, then Community plugins, then Browse. Install and enable "Send Email into Vault".
3. Paste the API key from your dashboard into the plugin settings.

Then authorize your Outlook address if it isn't the email you signed up with. Add it in the dashboard and confirm it from the email we send. You can add up to 3 extra addresses.

Students and academics: add your university address here. If you lose it after graduating, swap in a new sender. Notes already in your vault stay where they are.

Check whether your organization allows external forwarding

Many Microsoft 365 organizations block automatic forwarding to external addresses. That's your admin's setting, not something Email2Obsidian controls, and it's common for good reasons: it stops confidential mail from quietly leaving the company.

Signs you've hit it:

• The rule saves without complaint, but nothing ever arrives.
• You get a non-delivery report back in your inbox saying the message couldn't be forwarded.

If that happens, ask your IT team, and check your employer's policy on forwarding work email, including any confidentiality agreements or NDAs with clients. If automatic forwarding is off the table, skip to forwarding by hand.

Create the rule in new Outlook and Outlook on the web

New Outlook and Outlook on the web share the same rules settings. Menu labels shift from time to time, so look for the closest match:

1. 1

   Step 1: Open your rules

   In new Outlook or Outlook on the web, open Settings, go to Mail, then Rules.
2. 2

   Step 2: Add a new rule and name it

   Choose to add a new rule and give it a clear name, such as "To Obsidian: Acme".
3. 3

   Step 3: Set a narrow condition

   Pick a condition such as From is [email protected], or Subject includes "invoice".
4. 4

   Step 4: Choose the Forward to action

   Set the action to Forward to and enter your Email2Obsidian ingest address. Don't choose Redirect to.
5. 5

   Step 5: Save and test

   Save the rule, then send yourself a matching test email and check that the note appears after the plugin fetches.

The important part is the action. If you see both "Forward to" and "Redirect to" in the list, choose Forward. Rules created here are stored with your mailbox, so they keep working when your computer is off.

Create the rule in classic Outlook for Windows

In classic Outlook, rules live in a wizard. At the time of writing, the path is roughly:

1. On the Home tab, open Rules, then Manage Rules & Alerts.
2. Choose New Rule and start from a blank rule.
3. Pick your condition, such as messages from a specific person.
4. For the action, choose "forward it to people or public group", not "redirect it to".
5. Enter your ingest address, name the rule and finish.

Classic Outlook can mark some rules as client-only, which means they only run while Outlook is open on that computer. If you want the rule running all the time, creating it in Outlook on the web is usually the safer choice.

Outlook for Mac and mobile

Manual Forward works everywhere, including the Outlook apps for Mac, iPhone and Android. For automatic rules, set them up in Outlook on the web so they live with your mailbox rather than on one device.

Good rules to start with

Narrow beats broad. A tight rule protects your allowance and keeps your vault free of noise. Some ideas:

• From your accountant: invoices and statements arrive with their PDFs embedded.
• Subject contains "Meeting recap": recaps turn into project notes. See meeting notes and follow-ups.
• From your supervisor: feedback lands next to your thesis notes.

Rules usually forward the original subject, so they won't add #tags for you. Use the plugin's folder and template settings to keep rule-forwarded notes organized, and save tagging for the emails you forward by hand.

If your organization blocks it: forward by hand

This works from any Outlook version and from your phone, as long as you can email outside addresses. Select the message, choose Forward, send it to your ingest address, and add tags to the subject on the way out, like Acme contract redlines #client-acme #legal. Remove the "FW:" prefix too, since it would otherwise end up in the note title.

To make it a habit, create an Outlook category or flag called "To Obsidian". Tag messages as you read, then forward the batch at the end of the day. The manual forwarding guide covers every client.

Watch your allowance

A broad rule can burn through emails quickly. Starter includes 300 emails a month and Pro includes 1,000. Paid plans also have a daily cap of 200, and emails over the cap aren't added and don't count against your allowance. If you're unsure how many emails your rules will use, our guide to choosing a plan has a quick way to estimate.

Troubleshooting

• Redirect instead of Forward. Edit the rule and switch the action to "Forward to".
• Sender not authorized. Add your Outlook address as a verified sender in the dashboard.
• External forwarding blocked. Look for a non-delivery report, ask IT, and forward by hand in the meantime.
• API key expired. Keys last 3, 5 or 12 months. Create a new one and paste it into the plugin.
• Over the cap. Check your usage in the dashboard. Emails over a daily or monthly limit aren't added.
