Blocking emails for certain addresses
Posted on 2008-11-17
We have recently migrated a large number of users from third party systems to our central Exchange platform, but have issues with people still using old email addresses within head office.
For example, we moved our training department from old AOL based addresses to the Exchange system with the same format addresses as all head office staff - but some people insist on using the AOL addresses still - probably those where Outlook remembers them when typing a name in.
How can we block emails to these addresses sent from our Exchange system and then have an error message sent back to the sender? This should remind them to use the new addresses in the address books as most are ignoring our reminders.
