Is there a document on performing detailed delegation wrt Exchange 2007? Lets take a basic example, I have 2 sets of recipient administrators Set 1 Must be able to administer only Exchange/Mail related attributes and Users A B and C in OU XXX Set 2 Must be able to administer Excahange/Mailb related attributes and Users D and E in OU YYY Set 2 must also be able to change the users description In Exchange 2000/2003 this can be done, can it be done with Exchange 2007 and the New GUI?

You can control permissions to this level of granularity by using the "permission" cmdlets (Get/Set-ADPermission in this case). The GUI delegation is only for the built-in delegated roles, which cover the most common delegation requirements. Evan

Yep. Also,2003 did not have a built-in recipient role (only View-Only, AG Admin, Full Admin), so the only way this was possible was by doing custom permissioning using direct AD ACL'ing. Take a look at the up-to-date online help for the description of the improvements in 2007: http://www.microsoft.com/technet/prodtechnol/exchange/E2k7Help/cb24ddb7-0659-4d9d-9057-52843f861ba8.mspx?mfr=true As Evan said, if you need to go beyond the built-in roles, you can use the same custom permissioning techniques used in 2003 as essentially everything is still ACL based in 2007.

Agreed, I am going to need to spend a whole bunch more time learning how to do this, (I actually prefer the CLI). I just have many questions when it comes to upgrading where detailed roles have already been defined, let me read the documentation and play around before I comment if the 2007 delegation is better

Is there a document that explains where to get started wrt exchange 2007 custom delegation, I want to take a normal user and assign rights to that user that gives him progressive rights to exchange 2007 eg, can I create a role that only allows someone to create and delete mailboxes only? etc etc..

I now have the answer, a new feature in exchange 2010.... looks like 2007 did not have this functionalityhttp://msexchangeteam.com/archive/2009/11/16/453222.aspx
