The native Outlook method (desktop / Microsoft 365)
- Start a new email in the Outlook desktop app or Microsoft 365.
- Open the Options tab in the ribbon.
- In the Tracking group, tick Request a Read Receipt (you can also tick Delivery Receipt).
- Write and send your email as normal.
If the recipient agrees, you’ll get a confirmation email when they open the message. The operative word is if — they’re prompted, and they can decline.
Why this so often fails
- The recipient can decline. Outlook shows a prompt asking whether to send the receipt, and most people say no.
- It breaks outside Microsoft. Send to a Gmail, Yahoo or other non-Microsoft recipient and the request is usually ignored entirely.
- Free Outlook.com can’t do it. The web version has no read-receipt option at all — see does Outlook.com have read receipts.
The better way: a read receipt that can’t be declined
A read-receipt tracker records the open with an invisible pixel instead of asking the recipient for permission — so there’s no prompt to decline and nothing that breaks across email services. Vidi works on free Outlook.com (where native receipts don’t exist) and shows the status as WhatsApp-style ticks:
- One grey tick — sent.
- Two green ticks — opened by a real person.
How to set it up
- Install the Vidi extension from the Chrome Web Store.
- Sign in and pick a plan (30-day money-back guarantee).
- Compose and send from Outlook.com as normal.
- Watch the grey tick turn to two green ticks when your email is read.
Vidi turns the tick green only on a genuine human open, labelling automated pre-fetches honestly — see Apple Mail Privacy Protection and open tracking. For the full Outlook overview, see read receipts for Outlook.com, or get started with Vidi.
