Hello,

we changed settings as suggested here, however, mail sent via OWA or Outlook are always QP.

For our business purposes we need to have all mails encoded in UTF-8 format.

We use Exchange 2013 fully patched. 

Content-Type: text/html; charset="iso-8859-1"
Content-Transfer-Encoding: quoted-printable 

If anyone can suggest some solution, i would be thankfull, as at this point i don't know where to look for setting to force owa to use UTF-8.

Thanks in advance,

Ivica

Hi,
 
According to your description, I understand that you want to force OWA to use UTF-8.
If I misunderstand your concern, please do not hesitate to let me know.

We can modify the configuration of OWA virtual directory with OutboundCharset parameters, the command as below:
Set-OwaVirtualDirectory -identity "Owa (Default Web Site)" -OutboundCharset AlwaysUTF8
Note: The AlwaysUTF8 character setting on the Outlook Web App virtual directory takes precedence over user-defined settings. Outlook Web App sets the UTF-8 character on all outgoing e-mail messages, regardless of the user's language choice in Outlook Web App.

Additional, we may be enable the UTF-8 Encoding in Exchange server by install relevant language, please refer to:

Hello and thanks for suggestion Allen, 

you suggestion didn't helped.

After change its same as before:

Content-Type: text/plain; charset="iso-8859-1"
Content-Transfer-Encoding: quoted-printable

We have separated Mailbox and CAS , maybe this needs to be set on back-end OWA?

Thanks!

Hi Allen,

can you please help :)

this is still not working.

Basically we use app that needs to have in header folowing when sending from owa:

Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: base64

now we have:

Content-Type: text/plain; charset="iso-8859-1"
Content-Transfer-Encoding: quoted-printable

Any suggestion is more then welcome!!

Resolution is if you have backend servers to also set settings in backend owa:

Set-OwaVirtualDirectory -identity "BACKENDSERVER\Owa (Exchange back End)" -OutboundCharset AlwaysUTF8
