When someone asks you a question, of course, they want an answer. Our problem is, that sometimes we don't have an answer for them, and saying "I don't know" is not good enough. Working in an English speaking workplace, there are other, more appropriate phrases we can use. Saying "I don't know" can make you seem unprofessional and it may make you seem uninterested in the question!
Instead we can use these phrases which are more suited to the formal forms required in Business English.
These phrases show that we don't know the answer - without looking stupid - and that we are going to be helpful and get the answer for them.
1 - Good question. Let me get back to you on that.
2 - I don't have that information right now, but I'll be happy to get the answer for you.
3 - I can't remember off the top of my head. I'll check that out and get back to you.
4 - I've been wondering the same thing. Let's find out together.
5 - Let me double-check and then get back to you.
6 - That's not my area of expertise. Perhaps Person's Name can shed some light on it.
