Staff - What is the maximum file size for an email attachment?
Information Services is a major University administrative department with responsibilities covering library, academic and administrative computing, digital communications, media-technology services and reprographic services.
The maximum recommended file size for an attachment that you can send in one email is 20MB. Above this figure, you are at risk that the email will not be sent due to file size limitations.
Information Services recommends that you use file compression techniques like Zip in order to reduce large file sizes prior to sending.
