Many email services will allow you to view and use email using a desktop client (like Outlook Express or Thunderbird), as well as allowing you to check your email using a web browser (like Internet Explorer or Firefox). However, some email services will only allow you to check your email remotely using a web browser; they do not allow you to send and receive messages from a desktop client. These are sometimes called “web-only” or “web-based” email services.
Our experience with web email services has been that there are difficulties in receiving and/or opening the eShuttle attachments. For that reason, we recommend not using web-based email to receive files when using eShuttle.
