Anyone know the limitations of Microsoft office 365/exchange regex implementations? I am setting up DLP and i feel like i keep having to bang my head on the wall trying various regex combinations before i get something that actually works. I am left feeling that Microsoft's interpretation of regex is anything but standard and think i am running into escaping issues with special characters.
My current process is as follows.
go tohttps://www.debuggex.com/to build/test regex
implement in office 365 and when it doesn't work go back and try to create a simpler regex.
After enough tries i can get it to work and while i am not a regex expert, i have been building fairly complex regex's for years so am more than familiar with the basic syntax. Also in many cases i am simply trying to reuse regex's that i have already been using for years on...
