Can anyone help with an issue that I have with Exchange 2003, basically I have been thrown in the deep end on active directory with hardly any training. So basically I don't know sh*t!

I will explain what I have done so far -

Migrated users account - Most of them successfully migrated
Created new resources on my ads branch in the resources option on ads

My problem is I have created a distribution list and added the resource that I have created!

I have logged on as that resource i.e. res******* logged onto Outlook with no issues. I then change the permission for the root of mailbox to add the Secretaries group dl****** , after this I add the dl group to mailbox root permission and via delegates to accept meeting!

I cannnot even browse the first folder even when I add the Secretaries directly to mailbox instead of through a distribution list!

I have given time for replication through the system i.e. 24 hours - Don't know what the replication is time (was told 15 Minutes) not convinced thou!

I woul greatly appreicate any help or links!!!
I am also checking m$ and google for information relating to this problem
