Are these sentences awkward?

Question

1. She is calling in connection with an order she placed for a computer.

2. She is calling in connection with an order she placed.

3. She is calling in connection with the order she placed for a computer.

4. She is calling in connection with the order she placed.

5. I'm calling in connection with the order we placed a few weeks ago.

6. May I ask what this is in regard to?

7. May I ask what this is in connection with?

Answer 1

"In connection with" is awkward wording although not necessarily incorrect. I would have said "in regard to". It sounds more professional and flows better. Connection is just not the right word for sentences like these.

Answer 2

In connection is awkward, try concerning.

Answer 3

I think number 7 is awkward.  The others are ok, but I would say "in regard to..." instead of "in connection with..."

Answer 4

no ..they are all correct.....with subtle differences
