There are about 230 people in the office where I work. The subset of upper management that knows has put together a communication plan to disseminate the information while I'm on vacation. My last day at work as Tim is April 8, then I go on vacation for 2 weeks. On Monday, April 11, the communication plan goes into effect, starting at 8:00 am, when my immediate team will be brought in and given the news, followed by all of IT, followed by all the managers of other departments, who will be told that they need to meet with their teams to give them the information. By noon that day, everyone in the office will have been communicated to, and the clear message to them is that no form of intimidation, harassment or ridicule will be tolerated - at all. The next day, an external consultant will hold workshops for everyone who is interested (they will be STRONGLY urged to attend). She is a transwoman herself, and a very good speaker. Then everyone will have the rest of the 2 weeks to digest the information and get used to the idea. I expect when I return, I will have an easy time of things. I'm sure there will be some who initially have difficulty with it, but I'm counting on the idea that to the extent I present myself with confidence, as a normal woman, people will get over their discomfort in short order.
