Sending large files via email creates problems for IT

    Sending large files via email puts a real strain on email servers and IT teams. As the average file size of presentations, videos, images and other documents continues to grow, sending large files via email becomes next to impossible. Email sent with large attachments can quickly clog up inboxes and degrade the performance of email servers, which is why most IT teams place strict file size limits on email attachments.

    While these restrictions may protect system performance, they severely limit user productivity. Users need the ability to share large files with colleagues outside the organization as part of their day-to-day workflow. When emailing large files is impossible, users are likely to use third-party file sharing services to meet their needs. But because these organizations can't offer the same level of security and protection against data leaks, content being shared is exposed to greater risk.

    To resolve the dilemma over sending large files via email, Mimecast provides an easy-to-use solution for big file sharing that meets the needs of users and IT administrators alike.
