Outlook Contacts, Address Book, and Autocomplete

› Outlook › People › Outlook Contacts, Address Book, and Autocomplete

Last reviewed on October 6, 2018     127 Comments

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.

Contact form
 

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.
Address book

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.

autocomplete list

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.

I am trying to import names and email addresses from Windows Live Mail into Outlook 365 for one of my clients. There are something over 3000 names and addresses. She would like to have the function in Outlook 365 similar to what she had in WLM. In a new email. start typing the name in the 'to' field, and have Outlook show a list of matches from the Contacts folder. All the names show in the 'Address Book' displayed when clicking on the button on the Ribbon, and will fill in if you click in the next address field, but not display a list to choose from.Is there any way to do this besides a registry edit or starting an email and putting all 3000+ names in the 'To' field? I tried your 'disable auto complete.reg fix from an earlier post, but it doesn't seem to restore the old behaviour.

There isn't a registry edit. The list is populated as you use it. You can prepopulate it by addresses a message and saving it in drafts - you shouldn't need to send it. But note that Outlook only saves the most recent 1000 addresses you sent mail to - so you won't want to add all 3000 names to the list.

Outlook uses autoresolve - if the name is unique, outlook will find the match. If not, it will underline the name and a right click will list all for you (the client) to select from. The next time you type it, outlook will use that entry, so for example, if you have 6 Ron's or Ronald's you'll want to type enough of the name to be unique, not just Ron, or it will default to the first Ron you send to.

So, it looks like there is no way to get the functionality she had in Windows Live Mail, where the whole address book was available to look up addresses in as you type!
I guess I will have to install Thunderbird for her. It still works well!
Thanks for your reply.

Correct, the address book is not available for "type ahead" but names will resolve automatically, so you don't need to click To to open the address book.

In re-reading this - i'm not sure what you mean.
>>All the names show in the 'Address Book' displayed when clicking on the button on the Ribbon, and will fill in if you click in the next address field, but not display a list to choose from.
>>

You can click To then type the name in the search field - if you use the name search it jumps down to the display name that begins with those letters. double click to add to the To field at the bottom of the dialog, then click Ok. A More columns search will search other fields too, not just the name field. It's not as convenient as WLM method, but it does show you all names.

Hi Diane,

I have suddenly found in my Apple Mail product that it is creating contact cards for every single person I send or receive mail from - No name - just the email address. I have spoken with Apple and they suspect it is a Microsoft Exchange issue - Any thoughts? Is there a way for me to turn it off?

Well, exchange will create entries in the autocomplete cache. What is the name of the folder these contacts are created in? Are you using Outlook desktop or Outlook on the web?

You can turn off the autocomplete feature in Outlook but you may not be able to delete the folder.

Hi Diane - I'm using Outlook 2016 on a Windows desktop. Do you know if it's possible to add Contact Groups to the list of Auto-Complete options? It seems to be only suggesting 'People'. We've tried emailing the Contact Group once but they don't appear in the Auto-Complete options after that. Thanks!

Hmmm. groups should be in the autocomplete list (in either the new recent people or suggested people) if they are in your contacts folders, but it looks like only exchange server groups are. I will check on it.

BTW, if you type enough of the group name to be unique, the name will auto resolve. Not quite autocomplete, not also not forced to pick from the address book.

Apparently this is a bug - microsoft is aware of it and are working on it. Support repros this issue on version 1710.8625.2121 (I have 1711 and repro it too), but not on Build 8201.2200 and Build 8431.2107. If you really need this feature, roll back to either build.

Diane, I send emails via outlook 2010 using vba. The user is on a company Office 365. I recently found that for one user that had multiple email addresses for a single contact the emails would fail with not resolved error. After tossing the extra email addresses in Contacts all are now able to send - except for one of them. That contact had the most email addresses of the group. I find that if I log in to Office 365, many of the old, removed email addresses are still visible; some show source as "contacts" and most don't show a source. Can you think of any way to clean up the addresses for this one person so that the emails won't fail?

>> most don't show a source.
if the contact card doesn't have a source, it is probably from the autocomplete list. If those 'bad' addresses come up when you type in the to field, delete them.

I did delete the entry that was 'bad' that came up when typing in a name; it didn't change anything. After deleting from outlooks autocomplete, they still appear in Office 365, as email addresses for those People.I did that days ago, just couldn't include all of the things I'd tried.

I hope you can help me, Diane. Very recently purchased Outlook 2016 for my
also recently purchased HP 2017 Windows 2010 computer. It appears that the
Outlook program's Address book is either not functioning at all or I just don't know how
to Import my 2 Address Books from Outlook 2010 from my old computer. Is there a
glitch in 2016 or a "fix" still to come...or can you guide me as to how to make it work
properly?

Going crazy!

What exactly is happening? The contacts are stored in the data file if you use pop; in a pst or ost with imap, and in the mailbox on the server with outlook.com. For a pst, you really just need to copy it from the old computer. Imap's 'this computer only' folders need to be exported.

Diane, Your knowledge is much appreciated. I do have a question that I do not know how to correct. I am using MS Office 365 just installed this year. I was using MS Office 2010. When I type my name I like it to auto fill i.e. I type Ron F, it will fill/complete Ron Faulkner. Problem: I do not know where to edit this feature in Word or in Outlook when emailing. Currently it auto completes as Ronald Faulkner. Any ideas? Thanks, Ron Faulkner

I have been adding new contacts in Outlook but sometimes when I put in a Company name the information can randomly disappear. Even when I have saved it I will go back and find that the company has gone leaving just the job title, phone number, email and the persons name. Can anyone help me with what I may be doing wrong? Many thanks,

This is a known issue with some outlook.com accounts - they are working on it. Are you syncing with a phone? It seems to be more of a problem with android.

Is there a way to link a company name to an email address so that when I type the company name in the "TO" field their email address auto populates?

You would need to put it in the full name field.
