To the geeks and would-be geeks (like me) on this board, here's a question I would like to throw around about Outlook Express. I am currently on training status with a large cable company who is also a broadband ISP and yesterday we had this call (while I was side jacked but the one taking calls) from a nice gentleman from the West Coast. His problem was that he had no issues when sending out mail, either through Outlook Express, or through another email provider, or through our company's webmail. The issues begin when people send him mail. They (the senders) get bounce back error messages, like our servers were rejecting their emails to him. My initial thoughts were that his mailbox was full, or that the packets of email being sent to him were just too large, but the upper level tech who I was sidejacking with decided to elevate the issue to the upper tier, who insisted that nothing was wrong with our servers but did not give any answer to the issue either. We ended up with the client a little bit more upset than when he first called in, and me having to tell him he will be called back. I think this was an easy problem, and the reason the tech I was sidejacked with elevated it to the other tech was because it was nearing his shift's end and he hoped the other tech would take the call, which did not happen. But, on the other hand, there may indeed be more high tech issues involved than mailbox overflow or size. That area is currently being migrated from one ISP/Cable provider to another. What do you geek types think ? And thanks for any suggestion and advice.
