If you have a reliable backup procedure in place, you can use the Recover Deleted Account utility to restore recently deleted user and resource accounts from the backup version of the GroupWise primary domain database. After the account has been re-created, you can then restore the corresponding mailbox and its contents to complete the process. Membership in distribution lists and ownership of resources must be manually re-established.
For complete instructions, see Section 32.6, Recovering Deleted GroupWise Accounts.
