Hello,

I have an Exchange 2013 server hosted on-premises. User A sent an Email to User B. User B received the message content successfully in English. When the User B replied back to the User A from the iPhone, the message content of the User A in the reply message appears to be in Chinese for some reason. I have provided the sample content below, does anyone else come across a similar scenario?

Thanks!

Check the language settings on that device

Also run Get-Mailboxregionalconfiguration and the language type for User B and see what language he has as a default one

Thanks for your reply. The language settings on the device is set to English. I also checked the Get-Mailboxregionalconfiguration earlier, it is set to "en-us".

Hi,

If this issue just occur on this user, then the major cause could be the setting on iPhone.

So does this issue occur on all user?

And if the User B reply message from Outlook or OWA, does this issue occur?

Best Regards.

Thanks for your reply. Not for all the users, just for that particular user and the Email. 

By the way, I removed the External URL for Outlook Web App and restarted the IIS. However, the changes are not reflected it. Any thoughts on this?

What do you mean the changes are not reflected?

The External URL for the OWA is still pointing to the old URL even though it is removed. I am still able to access the URL.

If you don't block the URL at either the firewall level or the load balancer level the URL will still function, as you can still make a connection to it.  Just because you get rid of the configuration in Exchange, doesn't mean IIS will start denying connections.
