The most common reason for a mail program crashing in the middle of a download is that the message has an attachment that is too long. Recently, more and more people are beginning to send large files over the internet via email.
This was never the purpose of email and many email servers were not designed to handle such large attachments. The result of this is sometimes email attachments become corrupted making them impossible to download.
The best solution to this problem is to give our Technical Support a call at 888-988-8508 with your user id and password and we can clear the mail directly from our office.
