Get Outlook 2010 "To... Textbox" To List Alphabetically When It Drops Down

Hello Experts -

I am trying to clean up the email addresses that appear in the dropdown when I enter the first character of the contact's name that I wish to email.

I want the dropdown list to display in ALPHABETICAL order - not based on the frequency of use.

Also, is there any way to stop Outlook from adding new contact information, unless I specifically add it myself?

Are there options or Registry values that would make this functionality possible?

Thanks for your help.

First question: Outlook always uses the most recent. That fits me perfectly and alphabetic would not work for me. I do not think you can change this.

Second question: Yes. Outlook 2010 Options, Contacts and uncheck the setting to Automatically create contacts. This setting is gone for sure in Outlook 2016 and I think also in Outlook 2013.

Thanks very much for responding, John.

I found the Outlook Options screen that you mentioned and made the appropriate change to "turn off" adding contacts automatically.

How about if we wait a bit to see if anyone knows how to list existing contacts alphabetically in the "To:" dropdown?

Thanks for your help.

Let's see what others say. It looks like you need to sort the actual list before using it.

Your comment about sorting the list before using it triggered a thought.

I am working with a utility called NK2Edit Version 3.07 by Nir Sofer to clean up the file that is used to load the dropdown.  See

On the menu "Action"  there is a sub-menu called "Sort Index By Drop-Down Name". I clicked on this, and bingo the drop-down is in alphabetical order. There is also an option to put the file back in sequence by frequency of use.

That did the trick. Without your suggestion I would never had thought about pre-sorting the file.

So, you're the star!
