Just migrated a customer to a hosted Exchange 2013 service from an in-house Exchange 2003.

A month after the successful migration a filtering requirement has come to light that I wasn't made aware of before the migration i.e. they need to block outgoing emails that contain 16 digit strings (credit card numbers).

Previously they had used an external filtering service that provided this functionality.

Unfortunately the Exchange host they've moved to is not able to provide this functionality.

So we have two options as far as I can see...

1. Migrate them again to a service that does provide the necessary filtering - the reason for choosing the current supplier is that they stipulated the requirement for a UK data centre.
2. Find some way to do this via Outlook rules - although this doesn't prevent users disabling the rule and it won't work for OWA as far as I'm aware.

Anybody got any bright ideas?
