So how do I respond when I do not know an answer to a problem? So, for example, if a message is sent by email and I'm not sure, I usually message that person back like, hi, I don't have an exact answer for you, but let me do some research and I will get back to you. I think that's the easiest way you can tell someone like you're not sure you're not beating around the bush. You don't want to sit here and make up excuses. You just want to cut to the point. And that way you can work on getting an answer for what they're asking you. As far as being on the phone and someone asking you a question, it's you can place them on hold and try and do research there. You can always contact someone else and see if they have an answer. Just try to use your resources and the time that you have and get back with them in a timely manner.
