EXCHANGE USERS
If your Exchange server becomes compromised, you may face a total system
rebuild. If your domain had been hacked, you may need to change it! Yes, I
know this is a disaster which is very hard to quantity. Once your domain is
hacked, you can expect an ever increasing rise in attacks and spam.
See the 'Changing my email address' link on the main 'headoffice.it' web page
for more information.
You will need to contact your Microsoft Exchange IT support to get this sorted.
We don't support Microsoft Exchange.
