Publishing mail list archives Messages sent to a mail list can be archived in HTML format so that they can be read through a web browser. This feature can be enabled via the Web Archive mail list property page.
To publish these pages on your website, simply create a new virtual directory within IIS:

1. Open IIS
2. Right click on your website
3. Add new virtual Directory
4. Follow the wizard to assign an alias name and point the virtual directory to the directory containing the Archive files for your mail list

You can now access your mail list archive pages via your browser:

http://www.domain.com/alias

For example, if you named your virtual directory "listhistory" you would point your browser to:

http://www.domain.com/listhistory/index.html

This can be done for each list that you wish to publish.
