ところをwhen you're so busy; when it should have been
Two uses. お忙しいところを comes before thanks, an apology or a request: you know this is a bad moment for the other person. The other use is "it should have been A, but it was B".
courtesy
I am sorry to trouble you while you are busy, but could you please check these documents?
should have been
It would normally take an hour, but we got there in thirty minutes.
Courtesy
い-adjective + ところ(を) / noun + の + ところ(を)
About the other person, so usually with お or ご: お忙しいところ, お休みのところ, お食事中のところ. The を is often dropped.
Should have been
Verb (plain form) + ところを / noun + の + ところを
Often べきところを, with 本来なら, 普通なら or いつもなら in front. With a price: 通常一万円のところ(を).
Before thanks, an apology or a request
You are breaking in on someone, or have put them to trouble, and you say so first. Then comes すみません, 恐れ入りますが, ありがとうございます or the request itself. People say it all day on the phone, in work email and at reception desks.

I'm sorry to call in the middle of your meal. I'll call back later.
On the phone.
Thank you very much for attending the meeting despite your busy schedule.

To a friend: no お, no を, and ところ shrinks to とこ.
When it should have been otherwise
First what would normally or properly happen, then what happened instead: a slip, a favor, a nice surprise. This use is mostly written, or said on formal occasions.

のにN4

It normally takes an hour, and yet we got there in thirty minutes.
