Regarding to the confusing / miss communication of the HTC & THHPT email.
Firstly we apologize for any inconvenience caused to you. I would like to explain for this matter.
Now THHTP ( Thai employee ) had to change the email to @infra-systems.hitachi.com
But almost HTC ( Japanese employee ) still usage the Hitachi email (@hitachi.com)
Therefore, We would like to re-submit the main employee contact list for your information.
Please find attached file and could you update in your contact list.
