I'm in an organization where I have nearly 30 smaller groups working under the parent domain. Each organization has different ideas on how to deal with user account deletion in AD and Exchange. I'm the sole admin managing this setup and have the following two cases and the environment is Windows Server 2008 and Exchange 2010.
1). I have a group of seven users who've left the organization. There's no need to maintain their account data or email, however, I've been asked to set an automatic reply for mail destined for those seven accounts along the lines of :
Username is no longer at this organization. Please contact email@example.com for additional information.
The actual messages do not need to be forwarded to anyone. Just discarded or dropped. Is there a nice way to do this?
2). Another user was laid-off. The AD account was disabled. It makes sense to forward mail for this user to his manager. However, what is the cleanest way to keep his old account intact for compliancy purposes (we also have email journaling via MailArchiva)? Would it be just delegation or mailbox rights? Do you just export the entire account to .PST? Is there a preferred way to do this, as it seems inline with what most people would have to do when people leave an organization.
Edit: I also have a Barracuda Spam firewall as the mail gateway.
