The correct choice of encoding for outgoing messages is sometimes necessary for faultless display of national characters in footers composed in languages such as Swedish, Greek, Spanish, Danish, etc. added by CodeTwo Exchange Rules, CodeTwo Exchange Rules 2007 and CodeTwo Exchange Rules 2010. The configuration of the encoding can be done directly in Outlook, which can be a solution only if we want to test the functioning of the program for one or several users. If however, we want to run the program on a production server, modifying settings for each and every client may prove too troublesome. In this case what we need to do is set a global encoding policy for Outlook users at Exchange.

We will be using Group Policy Editor and we will need a ADM file for Outlook used by our users. If we do not have it, for Outlook 2007 it can be downloaded here. More can be read here.

1. Run Active Directory Users and Computers

2. Right click the domain name and choose Properties.

3. Go to Group Policy tab and click Edit to change the parameters of the active policy.

4. Add the ADM file by first expanding User Configuration, and right clicking Administrative Templates. Add the ADM file by choosing Add/Remove Templates, Add and point to the location of the file.

When the file has been added, the list will include Microsoft Office Outlook. Go to Tools | Options, Mail Format, International Options. Double click Encoding for outgoing messages. Set its parameter to Enabled. Now you can choose the default global encoding for outgoing messages. Recommended choice is Unicode (UTF-8).
