I have a phone number, and I want to find the name of the person who lists that number in the Outlook Exchange Global Address Book at work.

If I use the More Columns option, no results are returned. If I use the Advanced Find window, there is no option for phone number.

I use Outlook 2007 as my client. I also have an iPhone.

Is there some other option that I'm missing?


It would be possible to use a Search in the Active Directory, itself.

Can you open "Active Directory Users and Computers" in your Domain? There you can choose at 'Advanced' the Field "Phone" and search there.

  • Ok, that seems to work. For bonus points, what if I'm on a computer that isn't a member of the domain? – daxlerod Jan 11 '12 at 13:21
  • I think it would not possible to search in the Domain if you don't have a User-Account in the Domain. – Crujach Jan 18 '12 at 14:48
  • I mean the computer is not joined to the domain, such as my home computer. I can always fire up the VPN and use RDP to connect to a computer in the office, but sometimes I don't feel like finding the authentication card. Thanks for the reply regardless. – daxlerod Jan 18 '12 at 18:41

  • "Telephone" for me - there's no way to search all the phone number fields - and I had to get the number in exactly the same format as it was in the directory. – Martin Dorey Jun 27 '14 at 4:53

If your computer has ldapsearch you can run the following command (just replace the square brackets with the correct info):

ldapsearch -b "CN=Users,DC=[company],DC=com" \
-h [ldapserver.example.com] -x \
-D "[DOMAIN]\[username]" \
-w [password] \

To find a phone number, I recommend using OCS/Lync/Skype for business client as your search tool. Try searching using just the last 4 digits as there is no enforced data standard for entering this information. Search under the contacts tab, and if this number is in the system you should see a match come up.


I selected all the contacts from the global list and added them all to my personal contact list.. took about 5 Min to select 1000 employees and 10 minutes to add them because of the thinking time from the pc

  • I think there were about 50k entries at this organization. But something to keep in mind if you have a smaller group. – daxlerod Sep 29 '20 at 20:03
