Hi all,
My environment : Exchange server 2013 CU23, I have 1 customer , they send me an email to my Exchange mailbox , my gmail and yahoo mail.
Here is the look on gmail and yahoo mail
Here is the look on my Exchange mailbox (OWA , MS Outlook , mobile)
What could be the cause of this ? And how to fix it ? Let me know if you need more information. Please give me some advice, thank you very much.
Update:
When a realuser@customer.com forward same message to my Exchange mailbox, it's normal.
The problem only occurs when message is sent from customer's automatic mailing system (noreply) , maybe it is stamped or altered with any signature software.
