O365 RegEx transport rules
Hello,
I'm trying to configure a regular expression transport rule in O365 and I have been successful in getting a large part of it to work but there is one part that has eluded me.
NOTE:...
While some articles mention 'regex' is supported for particular predicates with transport rules, it is not regex - the term 'pattern' used in documentation is more appropriate. You can only do some basic matching; supported tokens are mentioned here - note the absence of the 'zero or one' (?) for example:

The article is about Ex2010; AFAIK this isn't different in later versions. Also note that to its defense, allowing too complex expressions could - at scale - impact resources on the server side.
