Although all three sentence does say similar affects each once creates a different response.

Will: customer is assured you will do it and most likely will say thank you and move on.

Able: let the customer know nothing can be done right now but will possible been done as soon as I am able but no assurance.

Able speaks of ability. When the customer return and the system is up I am able to do it now. I wasnt able too earlier.

Will signals that I will keep that mind. Most likely when you return I will already have the resolution.

I feel that able is more positive because you limited by constraints that are not of your own will.
