We’ve filled out additional user information in Active Directory. Is it also possible to select users based on this information from within Outlook?
For instance, select all the users from a certain department.
You can indeed do this from the Address Book. If you do this while composing a message, you can also use the query results to address your email.
Open the Address Book (shortcut: CTRL+SHIFT+B) and select the Global Address List. From this point you can do an Advanced Find (shortcut CTRL+SHIFT+F) within the Address Book itself.
Advanced Find dialog of the Address Book to search based on AD attributes
Outlook 2007 and Outlook 2010 expose this option more clearly with the blue Advanced Find link next to the Address Book selection list. Also, if you simply want to search on any field, you can select the “More columns” option. Separate your query with commas if not all the words need to be found in a single column or field.
In Outlook 2003 and previous, you can press the Find Items icon as well to bring up the dialog or use the Options-> Find… menu within the Address Book.
