What is the maximum size for an e-mail message with attachments?

The maximum e-mail message size (including all attachments) that can be sent through the University e-mail systems is 35 MB (megabytes). This limit applies to both, Office 365 (faculty/staff e-mail system) and UWin Gmail (student e-mail system).

This limit is in place because e-mail systems are not optimised for sharing of large files. We have other tools and services in place for that. Sending large files through e-mail has a negative impact on the performance of the servers and network which affects all users.

If you need to share files that are large in size, e-mail is not the best tool for that. Please consider doing so though OneDrive or Large Files Drop Box (BFDB) tool. See "Related Articles" section on the right for more informaiton.
