Outlook substitutes spaces in email address as NAME <email>

Can this behaviour be changed or disabled?

When user types an email address in Outlook To: field, and mistakenly put space in there, the first word is identified as the Name and the second as the email address. As an example, just type dr. zhivago@what.ever. You'll be sending an email to "dr." and a different email address of that you expect. Outlook will send the email without any notification.

This is nice if you do it on purpose, and pretty dangerous if you don't.

Can this behaviour be changed or disabled?

Thank you for the post. The Internet Message Format below has the specs for email addresses listed: http://www.ietf.org/rfc/rfc2822.txt

If you want the ability to type the user name with spaces and for that to resolve to the correct email address, this can be done per the steps below:

1. You need to create an Outlook Contact

2. Put the user name with the space in the Display As: as seen in the example below:

Then when you are addressing an email you can type Dr. Zhivago with the space on the To: line and the name will resolve correctly, as seen below:
