Dynamic distribution groups for Exchange 2007

Give users the power to manage their own groups


Enforcing group membership in dynamic groups

Learn about Securitay™



Dear Tom,


First of all Happy New Year!  Here is a quick article that will introduce you to some no-nonsense technical ideas that may help you manage your Windows security groups and email distribution groups more effectively and efficiently.   


There's also a new product on the scene to give end users control over their own groups.  See Group Management Portal for more information.


Give Your IT Admins a Break!


With the economic downturn here now, companies are squeezing every penny in hopes of staying afloat. "Do more with less", we’ve all heard this before, except now it could be life or death for your organization.  Everyone is getting a frustrated trying to figure out how best to keep the organization humming while not giving your administrators a migraine. 


Key: Either delegate the duties or automate the tasks of managing groups.

Dynamic Distribution Groups in Exchange 2007 



Automating as many processes is the name of the game when it comes to reducing administrative burden.  In most enterprises there are generally two different types of Windows groups:  Security Groups and Email Distribution Groups (or DL).  In an article below we’ll touch more on dynamic security groups, but here we’ll dive into dynamic DLs. 


This functionality was originally introduced in Exchange 2003.  It was a great idea – how to keep group membership of a DL up to date and more importantly automatically.  At the time the feature was called Query Based Distribution Groups.  It allowed the admin to define a DL based on certain attributes of a user, such as City=Houston or State=Texas.  As new users are created the system will automatically query AD and include those users that met the criteria.


With Exchange 2007, the name has been changed to Dynamic Distribution Groups and the administrative interface has changed also.

This tip comes from


How To Get Your End Users To Manage Their Own Groups using Group Management Portal



Are you tired of hearing your IT departments complain they don't have time to do the real important stuff?


Are you sick of listening to end users scream about the time it takes to join a security group or email DL?


Do you want an easy way to let the business section handle their own groups?


Then read on...


As mentioned earlier some distribution groups can be created and maintained dynamically.  Unfortunately many groups are not dynamic, but static and must be handled manually.


For IT administrators, adding and deleting users from security and email distribution group can be the most miserable task.  Countless hours are wasted where they could be doing more strategic projects.


Securitay understands this pain and has created a tool to help.  It called Group Management Portal (or GMP).


The Group Management Portal application grew from knowledge and long use of a similar application that has long been used internally at Microsoft. Built as an internal proof-of-concept application many years ago, it allows any employee to create and manage their own e-mail distribution lists and Active Directory™ security groups. Over time, it has also become a key enabling technology and business-critical application at Microsoft that allows instant collaboration and delegated management of security policies all the way down to the lowest levels of the business units. The application has saved Microsoft IT administrators countless hours of performing mundane management tasks.


This tool works for security groups as well as distribution groups.


GMP has the following features:

  • Integrates seamlessly with Microsoft Active Directory™ and Microsoft Exchange™
  • Supports any size organization
  • Simple to use and understand by even minimally trained employees
  • Usage quotas preclude employee abuse
  • Comprehensive workflow capabilities including approval and notification
  • Application configuration through simple and intuitive web-based management interfaces
  • Constrain object creation to pre-configured Organizational Units

Companies using  GMP will see the following benefits:

  • Improved business processes for ad-hoc collaboration
  • Better security management of distributed information
  • Reduced Administrative and Help Desk costs
  • Empowered and more productive employees
  • Improved auditability

Enforcing Group Membership


Did you know?


Speaking of helping out administrators, here’s another tip around groups:  enforcing group membership.  Many administrators have already discovered the benefits of using dynamic groups.  It reduces the burden on administrators of having to manually keep group memberships up to date. 




Here are 3 solutions that can help you:

1-     Windows 2003 (with Exchange 2003/2007).  Out of the box, Microsoft offers dynamic group functionality for distribution groups (see above).

a.     Pro.  Comes out of the box in Windows 2003 Active Directory.  Very simple tool.

b.    Con.  Because it is focused on AD, it can’t do multiple directories, or for that matter multiple AD forests.  Furthermore, this only works with email distribution groups and not security groups.

2-     ILMv2.  The soon to be released product of Microsoft will include dynamic functionality.  Mark Gabarra talks in depth on this subject – see his blog entry

a.     Pro.  ILMv2, like ILMv1 is a meta-directory engine.  It is meant to bring together multiple directories by synchronizing attributes.  This includes synchronizing multiple Active Directory forests.

b.    Con.  One issue using this approach is the synchronization latency that happens with all synchronization solutions.  Depending on your environment this could take on average of an hour up to a day.  Another piece to consider is the implementation time of ILM2.  Typically ILM2 is part of an enterprise identity management project, not for the faint of heart.  Much planning and consulting is needed to ensure a successful implementation. Another limitation is the fact that using an ILM product assumes you have more than one directory.  So this won’t work if you have a single forest.

3-     Virtual Directory.  Optimal IdM offers a nice Virtual Directory that’s built on Microsoft .NET technology.  It has many more benefits than just managing dynamic groups, but that’ll be for another email.  Find out more about this here

a.     Pro.  Being a Virtual Directory there is no synchronization latency, because they don’t synchronize directories.  All the information is served up in a ‘Virtual’ directory that is updated immediately.  Furthermore, it can be used in a single forest or multiple forests/directories.  Finally the icing on the cake is the little amount of time to deploy the product.  Typically it can be up and running within 8 hours!  Don’t believe me, then ask for your own POC and verify for yourself!

b.    Con.  Regarding managing group membership, I haven’t come across a con yet.  Though in general it is not meant to replace solutions like ILMv2, as virtual directories do not provision / de-provision user accounts.  That’s ILM’s job!

c.       Added bonus:  Many people are frustrated that solutions around dynamic groups can’t be audited easily.  Well look no further than Optimal IdM’s solution as it comes with an easy tool for reporting and auditing.
