A zip file is already compressed - you really can compress it further.  You can remove files from it and send two messages, some files in one zip, and others in another.  Or you can use a third party tool like WinRAR to break it down into chunks that are less than 10 MB.  Or you can use a different mail system to send files that are larger than your mail system's attachment limit (Gmail, Yahoo, and Outlook.com all offer 25 MB attachments (or more)).

outlook.com, not Outlook the program (Outlook.com is what used to be HotMail)

Outlook the program can easily do larger attachments - but the mail server that acts as a "post office" and runs your mail (Outlook is a program for READING and SENDING mail, not the "post office") can limit the size of things.

You can also split it, either using compression tools to produce a "spanned" file or simply by using third party tools to slice it into manageable pieces that can be reassembled by the recipient using the same software.  I usually recommend HJSplit to take an already compressed file and split it into more manageable bits.

It's a free download, isn't bundled with anything else and has a "point and shoot" interface - point it at the file you want to split and tell it how many chunks you want it broken into.  The recipient saves all the attachments in the same place, runs HJSplit on their machine and points it at the first one in the series, job done :)
You can use winrar, a more compressed utility from rarfile.com
Also they provide converting to multiple files if you need it in small chunks.
