Although I’d been researching over the last couple of days, today was the first day back at the coalface after new year; and a long educational day it was!
Exchange 5.5 to Exchange 2003 is always entertaining – the environments are so old, those responsible long gone, and the documentation modest or non-existent – and this is no exception.
So whilst the early work went well (despite a third party’s installation of Exchange 2003 onto the network 2 years ago without telling the client!), but later on mailbox moves did not play so well. The test mailboxes moved fine, but the first real world one could no longer receive public email. Doing the usual “check through the logs” thing brought up a host of errors on the old server. But an hour or so’s work determined that these were actually nothing to do with it, but other errors latent on the old server anyway!
Well, at least the VB code I wrote to inject appointments into people’s calendars works a treat and the client can start to consider moving their application over!
