In some rare cases, special and/or accented characters may not be displayed as expected when the message is received after a signature is appended.
The most likely cause is that the character set in Microsoft Outlook is not set to send outgoing messages in Unicode (UTF-8).
Configure the character set in Microsoft Outlook to send outgoing messages in Unicode (UTF-8).
To do this:
- In Microsoft Outlook, select File > Options.
The Outlook Options window is displayed.
- From the left-hand side options, click Advanced.
- Within the International options section, ensure that Automatically select encoding for outgoing messages is set to Unicode (UTF-8).
- Click OK to save the changes.
