Hi, we have 3 digitally networked failover server pairs. We are using COBRAS to move users from A to B - once we have deleted users from server A we cannot cretae as the Globalsubscribertable still has an entry with the same alias in there - everything else seems to remove the entry i.e. nothing left in AD or Exchange . we eventually end up manually removing from the GST. This is not really practicle with large number of users being moved around. Any suggestions?
