Change the default file format for saving messages
Outlook 2010 supports Unicode, a character encoding standard that enables most of the written languages in the world to be represented by using a single character set. If you work in a multinational organization or share messages and items with people who use Outlook on computers that run in other languages, you can take advantage of Unicode support in Outlook.
If you want to save your messages in a Unicode encoding by default, do the following:
- Click the File tab.
- Click Options.
- Click Mail.
- Under Save messages, select the Use Unicode Format check box.
