The YouSendIt Outlook Plug-in allows users to send large files up to 2GB in size. Most importantly, you don't have to worry about e-mail bounce backs because of e-mail server restrictions since the attachment goes through the YouSendIt server. The Outlook plug-in handles network interruptions and resumes uploading your file when network connectivity is re-established. You can choose which attachments you want to send through YouSendIt Outlook Plug-in based on the file size. For example, you can choose to send all files larger than 1MB to go through YouSendIt automatically. You can also choose to be prompted whenever an attachment is being sent so that you can decide whether to send through YouSendIt Outlook Plug-in or the e-mail server.
