How to Search for an Email Address in Active Directory

From time to time I’ve had to figure out which user account has a specific email address.  Actually its more like finding who has the “reallycoolemailaccount@company.com” so another “more senior” person can get it.  Well if you work in a smaller company this can be kind of easy…but if your directory has thousands of accounts it becomes more difficult and time consuming.

What you will want to do is open up Active Directory Users and Computers and right-click the domain and select Search.  Select the drop-down arrow in the Find field to select Custom Search.  If you have multiple domains make sure to select Entire Directory on the In field.  Now just click on the Advanced tab and put the following text in the LDAP Query – proxyaddresses=smtp:<whatever the email is you’re looking for>.  Now all you have to do is click on Find Now and if the email is in use it will show the user account that is using it.

    hi Brian,

    Is there a DSquery / LDAP query string to list out users for a particular non-primary SMTP email address?

    Thanks very much and more power to your blog site.

    Hi Nathaniel,

    I don”t know of a query string that will do that…doesn”t mean it doesn”t exist though. 🙂

  4. 銀行の借入は、通常のカードローンよりも利息が低いという特長があります。審査時の基準で、しっかり毎月の収入のある人のみがキャッシングをすることが可能ですがパートや派遣社員の方も借入ができるようです。
    また、カードローンは24時間いつでもOKで、HPからお願いすれば手持ち口座へ速攻で振り込まれるというサービスも素晴らしいところです。特に、夜遅くに突然金が必要になったケースではこのサービスは非常に便利です。
    しかし誤解することが多いものの、カードローンの利用と借金は変わらないという意識を持って、融資はできるだけ最低限にしておかねばいけません。
