Outlook 2016 - chinese characters appearing in messages when replying/forwarding

We were facing this as well with some new Windows 10, inTune enrolled devices with Office 2016.

This was primarily happening for us when sending updates to meeting invitations but we were able to fix this by changing the Outlook Editing Language settings (File ==> Options ==> Language) to match the system settings.

For one affected user the system locale settings were set to English (United States) but the Outlook Editing Language settings were set to English (Germany). We changed that setting in Outlook to English (United States) as well, restarted all Office Apps and since then all meeting updates are sent without any Chinese characters appearing.

Hope this helps others as well.

I do not have a solution; I have the same problem, but only on my O365 account, working from home. Working on my corporate laptop with (presumably) accessing the same O365 account, the emails ALWAYS look normal. I use Outlook 2016 currently.

SUGGESTION: Attempt to open the email with the odd characters with a web browser.

I use the Move --> Actions --> View In Browser. For me the text looks perfectly normal in the browser, which leads me to believe it is a formatting error associated with my Outlook. In this scenario, I believe Outlook converts the email to a .mht file, stripping the offending formatting, rendering a normal output.

Other comments:

 - I have sent email replies that look perfectly normal as I type them. Then they are sent with the odd characters. They show in my Sent Items with the odd characters.

 - I have received attachments (Outlook messages attached to other Outlook messages) that have the odd characters. In some, the normal English shows up at the end for about 3 lines of text.

In all scenarios, my corporate laptop shows the emails as normal.

Sample characters: 

Beginning of 1st line: 格浴ｽ惓㩳㵶ｮa悵ｪrｵｵ

Random characters in email: 蓮顫本☮ｰ迸ｾ @畢ｩù⁉慣

In my previous post, I mentioned how one message did not contain an http link.  I asked the sender of that message to describe the app/device she used to send the message to me.  She stated:  The email was sent through my gmail account from my Apple laptop, Chrome bring the browser. 

ElBurgo, does your problem occur when there are no http links?  Or, are the messages to which you're replying coming from an Apple/Chrome environment?  

I hope someone who knows how to fix this problem will chime in.....

My issue is similar to ElBurgo: 

Body of text is replaced by 2 or 3 Chinese characters. 

It's always a Reply; not a new email.

Unlike ElBurgo:

No signature has been present when the problem occurs.

All but one time, the messages being replied to contained http links.

It's awful because the original body of the sent message is lost (there is no record of it).  The sent mail folder shows the email with the Chinese characters in the body.  

Exactly - we too lose the original.  The draft in the sent folder is corrupted as well.
