Duplicate contact folders?

If you’ve been using computers and Outlook for as long as I’ve have, you probably have had occasion to need to migrate from one computer to another and take your entire Outlook with you. You’ve spent a lifetime configuring and getting Outlook to respect your tastes.

One of the things that happens when you migrate to a new computer and setup Microsoft Office on it and start up your Outlook for the first time, it goes and creates an empty “Outlook profile” for you. There is no simple way (at least from a UI perspective, IMHO) to go and stop this. Outlook will always go and create an empty profile for you, the first time you start it. This is basically the reason that you actually get the duplicate contact folders problem in Outlook.

The typical prosumer / geek way of backing up Outlook for moving it to a new machine involves finding the profile’ PST file (typically in C:\Documents and Settings\YourWindowsUserName\Local Settings\Application Data\Microsoft\Outlook) and copying it over to the new machine. Suppose you do manage to attach the old data file to your new Outlook and get your basic email/tasks/calendar working again, the one thing that typically screws up is the Contacts. Outlook retains the old data file that was created (at least the Contacts part) and shows it to you in various parts of the UI. This can become most irritating especially when Outlook still retains the Contacts from the data file that it default-created as your default Contacts repository even though you have no contacts in it. All “To:“ button clicks, address book lookups, etc. will default to this Contacts repository with a UI option to switch repositories via a drop down list box which displays a stupendously amazing list of two items, both showing the single, innocuous word, “Contacts”, leaving you to figure out which-is-which. 

Now for the good news: It’s a pretty simple matter to eliminate this problem. Just use the “Tools – Email accounts” option and instead of selecting the normal Add / Change email account option, notice the bottom portion that you have become trained to turn a blind eye to, “Directory”. Use the “View or change existing directory or address books” option to receive a heretofore undiscovered dialog that lets you figure out a way to set Outlook’s address book selection preference and optionally even delete an address book. Yup that’s what you want to do. Only, you’ve got to figure out which particular “Contacts” book you’ve to delete, they are both named the exact same thing.

So, if you’ve been following me so far, I think it should be a simple matter for you to figure out the correct address book and delete it. The other address book quickly becomes the default and Outlook starts looking up contacts correctly again.

Or you could take the 0.5 probability chance to just delete the repository that shows by default. Is it the first item, could it be any one of the two, if you’re willing to take the gamble, you have a good 50% chance of success. I took it and was rewarded suitably enough to write this. However, I *do* recommend a full backup of your PST file if you’re actually going to go ahead and try this. DO NOT come back to me and tell me, “What you asked me to do ended up with me losing ALL my contacts.” You were warned.

Do tell me if you’ve ever experienced this problem, and your experiences with above solution. I’ve not taken the time/effort to create screenshots and upload them yet, but I will, if anyone finds it necessary. Do post a comment if you want this.

  1. Thank you for the great post! I do believe I have this problem but since I have not known how to deal with it I have lived with it for many months. Obviously, I think I have added new contacts in the default “contacts” but possibly made changes in the other “contacts”. Is there any way that I can merge these before deleting without creating hundreds of duplicates that I have to sort through to see which is most accurate? Should I create a PST file of one and then import it to the other? I still think I would end up with too many duplicates.
    Thank you for your comments.

  2. Ah yes, the other problem….. duplicates.

    For Contacts, Outlook itself handles a certain level of duplicates, where it “magically” catches your duplicates (when you drag and drop a new contact into the Contacts folder, or even more so when you import), *some* of the time. This is not reliable in any way, and I’m not really sure what criteria it uses to really find matching duplicates.

    Another solution is to use an external duplicate checker, like the ones from MAPILabs. While this is a more concrete solution, it is a commercial one.

    It all depends on the number of contacts you have really. If you can do it manually, i.e., if the number of contacts you have is manually processable by you, then it will probably acheive the best result.

    Hmm….. you don’t really have to create a new PST to backup your contacts, by the way. You can do it with a neat little drag-and-drop trick, which I’ll probably cover in another blog post.

  3. Thanks for the post. This problem has driven me nuts. Probably steals a full five minutes from any given day. Your solution worked perfectly.

  4. What a star! I’ve just reinstalled Windows XP and Office 2003 and discovered this morning that I had this problem — you’ve helped me fix it now. Thank you very much.

    p.s. I managed to delete the correct Contacts folder first time — yay!

    Thanks!!!!!!!!
    I was a little nervous about deleting the top folder but it worked.

  8. Thanks – again, deleted the top one and it worked beautifully!

  9. Wow! That was such a simple solution to a frustrating problem. Thank you!!

  10. I subscribe to Smart Computing, which offers a tech forum wherein the participants are folks like us who help each other through technical difficulties. I, too, was putting up with the nuisance of having to choose a second (duplicate) Contacts file whenever I wanted to retrieve a specific address from my Outlook Address Book.

    I went through the Smart Computing Q&Q forum, where users ask questions and others, as I have said, answer them. I arrived at the same answer you provide here with the help of ‘Kathleen’ and ‘mes00b’ and ’sare’ in that forum. You have cleared up a lot relating to the background of the problem, and perhaps you shine a light on what developers of Outlook and similar products should consider as they navigate Operating System waters going forward.

    You can find the details of my duplicate Contacts folder dillemma here http://tinyurl.com/3405120 and here http://tinyurl.com/3405704.

    I was (still am) reluctant to delete either of these Contacts files, but having read your post here I feel 100% confident that I can do so if and when I choose. In the meantime, I have resolved the symptoms and my dilemma vy choosing the second of these Contacts files. Thank you very much for your detailed post, and an opportunity to contribute, such as I can.

    I am helping a friend with two contacts folder. But he wants to keep it that way.

    However, he wants to use the one called “contacts 1″ as the default for email addresses when he start typing into the “TO:” line.

    Currently the older folder “contacts” seems to be the default.

    How does he change the default to “contacts 1″? We scoured through all the menus, there is no menu item we could find to change it.

    Thanks
