AOL restricts emails to a maximum size of 25MB, inclusive of the message text and any attached files. Attachments that force the email to exceed this limit cannot be delivered, but correctly sized attachments are available for download within the email. AOL does not offer the option to open attachments directly in the AOL window, but Internet Explorer and Mozilla Firefox both support opening AOL attachments for viewing with a selected application without permanently downloading the file first.
