Next time: "How to share files that are too large to attach to emails"
Question: I am trying to send an attachment to my email in Zimbra webmail. What is the limit on the file size?
IT Help Desk: The limit for each email in K-State's Zimbra system is 50MB (megabytes) including attachments. That’s 51,200KB (kilobytes); 1 megabyte = 1,024 kilobytes. That is substantially more than most email service providers allow (typically 10-25MB). So, when you are considering sending a large file attachment, first check the file size.
If you send a file as an attachment (because it's not text), that needs to be encoded -- which typically adds roughly 30 percent to the file size. That means the upper limit for a file attachment(s) is closer to 35MB. It depends on the content of the attachment.
