What does olunca mean here?

Olunca comes from olmak and the ending -ınca / -ince, which often means when, once, since, or because depending on context.

Here, çok büyük olunca means something like when it was too big or more naturally because it was too big.

So this ending does not always mean only time. It can also introduce the reason for what happens next.

Why is it çok büyük olunca and not just çok büyükken?

Both can relate to a situation, but they are not exactly the same.

• çok büyükken = while it was very big / when it was very big
• çok büyük olunca = when it became/was very big, often with a stronger sense of result or cause

With adjectives, Turkish often uses olmak to express the idea of becoming or ending up in a state. In this sentence, olunca works very naturally because it connects that state to the next event: the email did not go.

So çok büyük olunca sounds like:

• because it was too big
• since it turned out to be too big
