IIJ Expands Functionality of the IIJ Document Exchange Service.

Update makes exchanging files even easier, with a corresponding increase in user convenience

TOKYO -- Internet Initiative Japan Inc. (IIJ, NASDAQ: IIJI, TSE Mothers: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today released a range of new features on the IIJ Document Exchange Service, including web-based e-mail and domain sharing. Adding the web-based e-mail feature to the online storage service enables customers to easily distribute large files that cannot be sent as attachments, thus creating even greater convenience for our customers.

The IIJ Document Exchange Service gives customers access to the IIJ-managed storage server, where they can upload large files and share them with others over the Internet. These files can be accessed from anywhere on the Internet, making them easy to share from remote locations or with people outside the organization, and eliminating the need to share information via removable storage such as magnetic optical drives or CDROM.

Each new feature provides more convenience, flexibility, or security for IIJ Document Exchange Service customers.

- Web-based e-mail feature added to Web interface

A new web-based e-mail feature has been added to the Web interface that customers can use for managing file uploads and downloads. When users send files using the web-based e-mail interface, the attached file is automatically uploaded to the IIJ Document Exchange Service server, and the URL to that location is inserted into the message. The procedure is the same as sending conventional e-mail attachments, but it automatically incorporates file exchange using the online storage service.

For existing customers of the IIJ Document Exchange Service, all features are accessible through a single Web interface -- from uploading files to sending messages -- increasing the simplicity and convenience of the service.

The user authentication feature prevents files from being accessed by unauthorized users if messages are mistakenly sent to the wrong address. Mail archive and URL access logs are accessible on the Web, so customers can monitor activity for even greater security.

- Shared domain features added

IIJ has added the shared domain feature, which enables customers to use the IIJ shared domain name as their host name. Not having to register their own domain name means that customers can get their website up and rolling quicker and easier. Customers are also spared the burden of obtaining their own authentication certificate, making it easy to exchange files in a secure environment.

IIJ plans to further expand functionality by linking IIJ Secure MX Service and other services with IIJ's corporate mail services.

IIJ will continue to expand service features to improve user convenience and provide even stronger security.
