Exchange 2013\office 365 transport rules to block ssn’s

exchange-2013microsoft-office-365

Hi i need help setting up a transport rule to block social security numbers, bank card numbers.

currently we have the office 365 midsize business plan, it does not have "data loss Prevention".

everything i look up is for exchange 2010 and not 2013.. so im not sure it's the same.

I manage an O365 E3 tenant, so I have more features (including DLP). That said, I do show a canned rule under Mail Transport Rules: Generate an incident report when sensitive information is detected. See below:

Exchange Rules in E3

When configuring the rule, you can curate a list of sensitive information types, US Social Security number is in the list, as well as many other canned types. When the rule is met, you can generate a report, block the message, apply a disclaimer, etc.

You know what? I'm looking at the help for the function, it does seem this is directly related to Data Loss Prevention. Maybe use this post to sell an upgraded Exchange Online service to management.

As the OP figured out on their own, regex matches are now supported in transport rules. Technet Reference
