It's rare for condensation to form on the outside of double-glazed windows, but it could occur in the event that the seal between the glass and window frame has begun to weaken. This is more common in winter when the temperature is lower and it's more easy for condensation to develop. The most likely cause is a fault in the spacer used between the window and the frame. The spacer is often filled with desiccant that is highly absorptive and can absorb excess moisture.
The problem with this is that when the desiccant is saturated, it begins to break down and then moisture can start to enter the gap between the glass units. This could cause condensation and water to build in the gap which is difficult to remove.

Take measurements of the width and height of the opening in both directions Then, you can order an item of double-strength glass that is 1/8 inch smaller in both directions. You'll also need glass points, which are made of metal triangles that help to hold the glass in place.
With the window sash off the way, gently pry it off of the wood molding using a flat pry bar. You may have to scrape off old glazing putty with a utility knife or chisel. Then, use the heat gun to warm any putty that won't easily fall off. This will make it easier to remove.
