Outlook support
Outlook has a nice feature, you can assign a web URL to a folder. So in a nutshell you don't have to leave Outlook and start a browser to access the archive.
Prerequisite: have a working web interface of piler
Configuring Outlook to access the archive
- Make a new folder, eg. “EmailArchive”
- Right click on it, then select “Properties”, and the “Home Page” tab.
- Select or check the “Show home page by default for this folder” cehckbox
- Enter the URL of the piler gui, eg. http://archive.yourdomain.com/
- Click on the “OK” button.

Note that it's best if you configure single sign-on, so you can spare your users typing their credentials to piler.
