Visit http://owa.mit.edu, login, then hover your mouse over your name as appears on left hand side of screen above your mailbox list.
Please visit: Q: What is the attachment size limit on MIT's email system?. Also keep in mind that although MIT's email system allows rather large attachments, one cannot count on other email systems being as generous. Rule of thumb: do not email a document larger than 2 MB in size. Should you have a document larger than 2 MB, place it in ~/Public (where '~' denotes your Athena home directory). Send the recipient an email with URL to document, e.g. http://web.mit.edu/joemccarthy/Public/comintern_minutes.pdf. Or send Dropbox link.
Unless the document needs editing on the receiving end, PDF is your best bet. PDF is the only format certain to retain formatting, is universal and is free.
These tips should keep your email quota under control.
