Outlook Contacts, Address Book, and Autocomplete

Last reviewed on February 21, 2014

Many users are easily confused by Outlook's contact options - you have Contacts, the Address Book and the auto-complete list. Add Outlook 2010's Suggested Contacts and there is a lot to be confused about.

Contacts

Contacts is a folder to hold addresses & phone numbers - email addresses, snail mail addresses etc - and personal information like spouse's name and birthday. Basically all the stuff you'd write in an address book or on a Rolodex card in years past.

Address Book

The address book contains a list of all Contacts who have electronic addresses (a Fax number is an electronic address). It's not a "real" folder or contact list, but a virtual view of all contact lists available to Outlook.

Outlook Address Book

I like to compare Outlook's Address Book to a shoe box or desk drawer where, in the past, we kept address books, business cards, and scraps of paper with addresses or phone numbers. The Outlook Address Book is a container that holds all your sources for addresses. Outlook Contacts folders and GAL (for Exchange users) are the address books, cards, and scraps of paper containing addresses stored within the drawer.

Note: The top level listing "Outlook Address Book" is the container that holds all address lists (for many people, Contacts is the only list).

When you select Outlook Address Book, it will say that there are No entries in this Address Book. This is expected, since it's just the "box" your other address lists are stored in.

Auto-Complete List

The Autocomplete list contains the addresses that come up when you begin typing in the To field. It's just a cache of recently used list of addresses.

In older versions of Outlook, a lot of users stopped creating contacts and just used the auto-complete cache as their address book. Except the autocomplete list corrupted easily. Suggested Contacts was created for this group of people - they won't lose their addresses and the automatically saved addresses won't clutter up the "good" Contacts folder.

When I start to enter a name in the To... field, I am offered several possible names and addresses starting with that letter in a pop-up under the field, that do not correspond to ALL the ones that start with that letter in the contacts cards.

That is the auto-complete list offering names of people you recently replied to (well, the last 1000 people, so some might not be recent). You can disable this in options if you don't want to be offered any names. If you want to add all of your contacts to this list, open a new message and click To. Select all addresses and add them to the message. Close the message without sending and the addresses should come up when you start typing.

If you want to see a list of the addresses in the autocomplete cache, or import them into Outlook Contacts, you'll need to use a utility. See Autocomplete Cache utilities for a list.

Suggested Contacts (Outlook 2010 only)

Suggested Contacts are contacts Outlook created for you and are email addresses only. This is a feature saves all addresses you send email to, automatically adding the addresses of people you send mail to, to the contacts folder. These are people you sent email to who are not in your contacts folder (or who Outlook couldn't find in your contacts - the look up is not very good and you may end up with duplicates).

Note: Suggested Contacts is only in Outlook 2010. It was removed from Outlook 2013. When upgrading from Outlook 2010, the Suggested Contacts folder is left in the data file but Outlook will not add new contacts to it. You can delete the Suggested Contacts folder if desired.

    How do I put suggested contacts into a group in my contacts folder

    Diane,
    Do you know of a way I can 'import' a bunch of addresses into a bunch of people's AutoComplete .NK2 file?

    Thanks,
    Alex

    How do I move contacts from suggested contacts to my icloud contacts? Or move any contact from one list to the other?

  4. Jim Fouss

    still not sure how to remove the suggested contacts folder -- keeps popping up when I just want contacts folder in my address book

  5. John Reidhar

    If you want to add all of your contacts to this list, open a new message and click To. Select all addresses and add them to the message. Close the message without sending and the addresses should come up when you start typing.

    Worked for me.

    All of my clients use autocomplete. When I upgrade their computers, I either move the NK2 file or know that Suggested Contacts will save their addresses. Now that they are using Outlook 2013, which has neither of these features, how do I restore autocomplete?

  7. Pete Nayler

    So another step backwards for Microsoft. The Office pre-2010 NK2 file was in the %appdata% folder, and Office 2010 Suggested Contacts folder was stored in the mailbox itself. Now to migrate settings fully, we have to grab a file out of %localappdata%.... a file that has proven to be far less reliable than NK2, and harder to identify as well.

  8. Pete Nayler

    Whilst I agree that Suggested Contacts wasn't ideal, at least it aggregated contacts into the mailbox. Only one file to deal with, if at all - in the case of an Exchange server. Every single one of my clients use autocomplete and every single one of them need it transferred when they change computers. Outlook 2010 made that simple. It's just the method of implementation that was clunky. It was tough for people to fix if the autocomplete cache was corrupted - but I only came across that once or twice. Definitely a step backwards, in my opinion.

  9. Pete Nayler

    OK that's good news. Do you think I can find that information anywhere? Documentation is strangely lacking (or at least, very hard to find).

  10. Pete Nayler

    Thanks Diane, I'm not particularly fussed about you finding it for me, but I would think that it should be documented given the importance of the feature for most users and consultants.

    Excellent Instructions!!!

    How do I delete the old Suggested Contacts address book from showing up in Outlook 2013?

  13. Bryan

    The problem though is that it doesn't show up as a folder but only as an address book. How do I get it to show up as a folder or just delete the address book? Thanks

  14. Bryan

    The Ctrl+6 shortcut worked! I can now see it in the folders list but I still can't see it on the Contact/People page in the list of contact folders. I'm not sure why? By the way, I recently upgraded from Outlook 2010 to 2013. Thanks for your help.

  15. Bryan

    Thanks. I've made a copy of them as an Archive folder.
