Hi All,

Weird one here that Prof. Google cannot answer. 

I've got a user who uses Outlook 2010 as part of Office 2010 and then getting email from a particular customer the reply font changes from the standard to Sim Sun and sometimes it's just the body of the email and sometimes also the header too. 

Does anyone have an idea why this is happening and more importantly, how to stop it?

Thanks

Liam

Does this only happen to the emails from that particular customer?

What's the font of the original email? Please check if he/she have modified the reply font in File>Options>mail>Stationery and

Hi Aravindhan,

Yes, only from an external recipient, when emailing colleagues the font issue is not apparent.

The font of the inward email is Sim Sun, the font is not being changed at all. 

Here is the diagnostics I have carried out so far:-

Repaired and reinstalled MS Office

Sending and replying internally does not replicate the issue.

checked the Font used by going to FILE>OPTIONS>MAIL>SIGNATURES>FONT, confirms this is not the issue.

Equally the 'stationary' being used is the default MS stationary within Outlook.

Changing the stationary doesn't improve or worsen the issue.

The issue is only present when using HTML as the email format.

I've logged into the users machine as them and not been able to recreate the issue by sending test emails to myself and others.

I have recreated the local user profile on the machine and the issue also persists.

Formats and Regional settings are all US under control panel except for the time zone. 

The issue does not show on OWA. 

No other user in that office has the issue, the issue doesn't stop the user from working, the user percieves it as not appearing professional hence their concern. 

What about start Outlook in safe mode? Could be an third party add-in as this only happens to a specific

Safe Mode doesn't make any difference but I've now identified the root cause, just not sure how to get around it. 

When an email is replied to, the source formatting is preserved hence it changes the text. 

Is there anyway to stop this from happening or to reset it at each reply?

Hi, what did you find as root cause? I been having this issue today and figured out while I'm typing, I press ctrl+space and it changes my font to SimSun. If I try to change font back in font selection menu, it remains as SimSun. I figured out this happens across windows 7, not just outlook or office. Maybe this is your user's problem. I discovered it by typing to fast and trying to use crtl for copy and paste.

Interesting article here about editing registry:

I could not add a link, but remove the spaces from above

Hope this helps.
