Address List:

In this article, we are going to discuss about the functions of the address list in exchange server 2007 version. In simple words, address list contains the classified details of the contact address (user’s email address, mail contacts, public folder email address, distribution email address, etc). The address lists are built to make lookups more useable than the basic Global Address List. The Global Address list contains all the address in the exchange directory (in short contains all mail enabled objects), and by default this is available in all email clients. This pre-canned address book will suffice for small-midsized businesses. The custom address list can be created as per your company needs.

Global Address List:

1. A list from the AD with all mail-enabled containers in it.
2. By default, it is provided to every user within Outlook and OWA.
3. Additional GALs can be created for hosting environments that need isolation.

Offline Address Book:

1. Allow users to get AD info while offline.
2. It is available to both internal and external users.
3. Are distributed via web-site and via Public folder.

Dynamic Distribution Group:

1. Groups can be built based on AD properties like Department, State or Company.
2. Dynamic security group is not feasible; one dynamic distribution group is possible. For example, Suppose I need to create a group on the basis of company name and city location (custom attribute1). The above can be done by creating the dynamic distribution group. Any new addition which matches the above condition will be automatically added to the distribution group, that’s the reason why it s called as Dynamic.
3. Especially useful for location-specific communications.
4. Can’t be used as security groups.
5. Create them in the Group sub-node of the Recipient node.
6. Non-wizard filtering criteria can be used if you use the New-DynamicDistributionGroup cmdlet.
#New-DynamicDistributionGroup –Name “Groupname” –Alias “ABC_Company” –IncludedRecipeints “MailboxUsers,MailContacts” – OrganizationalUnit “Domain.com/Users” –ConditionalCompany “Domain”

Best Practice:

1.Address List:

a. Don’t create any unless you really need them, and then keep it simple.
b. Make list names clearly descriptive of contents.

2.Global Address List:

a. Stick with the default one if at all possible.
b. Create new ones only for client based isolation.

3.Dynamic Distribution List:

a. Make use of this group.
b. Don’t forget about the value of the non-wizard Dynamic lists.

Hope the above is informative.
