What is the maximum size of any attachments?
Each attachment cannot exceed 5MB however you are reminded that MIME and similar encoding schemes used by your email client (Outlook Express etc) can inflate the attached file by up to 40%. So a 3MB PowerPoint attachment may actually grow to over 5MB when prepared by your email client for transmission. This would cause the mail item to fail to be delivered even though you thought it was only a 3MB attachment. To be certain about delivery, attachments over 2MB should be span zipped (or use a similar program) to segment the items into manageable packets.
