Do they know your transitioning i guess is the biggest question, i myself am going through this at work.
The women i work with are being extra social, my manager is male and oddly i think hes kinda got a man crush on me lol.
Im not out yet maybe never who knows but i definitely act more femme now than before i outted myself to my wife.
I definitely agree its a special aura once you become happier with yourself both aesthetically ( i wear light makeup 24/7 now) and mentally ( i relate better to women now fashion wise and just in general carry on more conversations) that it acts as a sort of magnet, people feel more comfortable around you and thus interact differently than if your just another guy on the floor so to speak.
Best of luck to you it has been a rewarding experience for me so far other than the odd nigjtmare about being outted unintentionally.
