You can't directly see how many people have read your email in Outlook. Outlook doesn't provide read receipts like some other email clients.
However, you can use a few workarounds to get an idea of whether your email has been opened:
- Track your email using the "Tracking" option: When you compose an email, you can select the "Tracking" option, which will notify you when the recipient opens the email.
- Use a third-party email tracking service: These services integrate with your Outlook account and provide detailed analytics on email opens, clicks, and other interactions.
Remember, while these methods can give you some insight, they don't guarantee 100% accuracy.
