Issue of Converting an email to case

Hi everyone,

This is what I did,

1.Select an email in Outlook, click set regarding and chose an account

2.Click Convert to case, a window will popped up.

3.In this window, assign a custom then Ok

4.A new case shows up.

My issue is in the new case, account should be popped up as the account I did set regarding in the step 1? Is that correct ? Here nothing shows up.

Also how can I put email body information into description in the new case form.

Thank you,

Kei
