YouSendIt in Microsoft Outlook is a popular website for sending and receiving large files of attachments with your e-mails up to 100MB for free. It is freely available on their website with an easy to use Add-on which you can restart after installation and you will notice the YouSendIt button with a drop down menu for signing in, configuring settings and getting support. YouSendIt allows you to attach larger files to your email attachments.
I have been using YouSendIt apps since several years from now and have always been happy and fully satisfied with this Microsoft Outlook app. This small plug in makes it more efficient to send large attachments with my mails without having to navigate to the website. The upload time seems equal to using the site. The larger files above 100MB have different subscription plans that are for a pro, business or corporate account.
Signing Up
You can start using YouSendit plug-in by logging into your account or signing up for a new one in Microsoft Outlook app. As an individual user you are downgraded to YouSendIt Lite which should be adequate enough for personal mails.
Also check immediately the configuration, where you can designate YouSendIt for files over a certain size. Basically all you need to do is to configure proxy settings, compose a message and include large attachment as you normally would. You will have a confirmation message pop up and just click Yes and your file is sent immediately.
Just Do It
- Send files directly from Outlook
- Eliminate email bounce-backs
- Prevent exchange server slow downs
- Resumable upload- handles network interruptions
- Seamless integration- Configure the plug-in to launch when attachments are larger than a pre-selected size
Note
While the file is being uploaded to the YouSendIt servers you will notice that there is a progress bar and abort option where the plug-in button is situated. Next, click on the YouSendIt toolbar button configuration and select your uploading preference to decide when to use YouSendIt service for uploading the attachments. Now, attach a file with Microsoft Outlook and send it out. Outlook may automatically send your email using the YouSendIt service based on your configuration in the previous step or you may elect to confirm using the YouSendIt service.
Also you will notice a YouSendIt Outbox with a plug-in that includes support so you can contact for any problems. You should make sure to turn on logging to send diagnostic files for easier troubleshooting.
