I know there is variance among the community. Of my three trans friends 2 prefere being referred to by their post transition gender in the past tense and once preferes they/them.

A coworker who came out requested he/him until after they took time off for treatment and then she/her afterwards.

When asked if he wanted his name updated on an award plaque while away he said no. So when she returned we had only updated her door name plate and info in the company directory.
