Another tip is be sure you send only emails formatted in plain text. I have had problems if the format is rich text or HTML. When the msg arrives it shows as a blank page or I never receive it at all. I also use a web based client as it seems like Outlook still does formatting of the msg even when set to plain text. Every time I use Outlook the msg fails. Attachments can be added, but size limit is I believe 368KB. Newer phones may be able to receive larger msgs from what I have seen while browsing the settings on my new V9M.
