Modify users on a crashed Groupwise server

One of my clients has Groupwise servers at many sites.  The Groupwise server at one particular site crashed. I do not support their Groupwise installation, I am only following up as a favor, so I don't know much else about the environment.

Here is the question posed to me:

One of our sites has a GroupWise Post Offices crashed late last week. One of our other technical contacts is saying that it's impossible to delete or change any of the users at that post office until the post office is brought back online. Is that true? He says that we have to rebuild the server before the users can be deleted or modified. Can you confirm that? Below is the documentation he sent me on this topic.

Here is an exceprt from that other response she is questioning:

I don't believe there is a document explaining the details of this specific type of scenario. It is common knowledge to GroupWise Engineers and Administrators that systems need to be online and communicating properly in order to administrate user, resources, post offices and domains in a distributed environment. It seems Novell may have the expectation that services are restored in the case of a disaster rather than lost and no longer used. However, I did find an old technical document that does reference some of the information I have communicated. The keys to success are recovery of the failed secondary domain in a way that communication of information is possible and that no pending items are stuck. Failure or Inability to delete or change a GroupWise object is directly related to communication between a distributed secondary domain and the centralized primary domain. The technical document follows. **He goes on to include technote #10010584, How To Delete Secondary Domain (Last modified: 12May2003), http://support.novell.com/docs/Tids/Solutions/10010584.html
