I'm about to take a fairly extended leave in order to get a brain tumor removed. Everyone at my office is aware of what's going on and how long I'll likely be gone, but I'm not sure what to put in my out of office email message. On the one hand, I'm worried that putting that I'm out of the office for medical leave is too much information to put in a response email that goes out to clients, on the other hand, it seems unprofessional to say that I will return to the office sometime in the next few months.
Any suggestions? My manager has said that I should handle it in the way I feel comfortable.
