RegEx statement to recognise UPN numbers
I've gotten mail encryption working in office 365 and I'm looking to automatically encrypt or block messages using DLP.
So I'm looking for regex statement to find a upn and other for any other potentially sensitive info.
I'm thinking something like this for the upn
Is there a better option to find 12 decimals following one of the characters above?
Are there too many LEAs to put those as an option into the statement?
I could use the local lea but I'd be missing any students out of my local lea.
Any help / ideas very greatly appreciated.
