Hi guys,
Recently we changed ISP from BT to Connexin at work because the distance to our BT exchange is approximately 7 billion miles so our internet was dog slow (less than 2meg for a network with 20+ systems), and the new connection is great. However, about 3 days after we stopped being able to send emails from outlook via our 1and1 SMTP server. I assumed it was a problem with the ISP so I called them and they changed our static IP.
Now I am able to send emails fine from my computer, but another person in the office still gets the same error: "Cannot find email server". I am pulling my hair out with this, we both have EXACTLY THE SAME settings (always have done) and yet I (reserved DHCP 192.168.1.13) can send emails fine, the wife (static 192.168.1.7) cannot.
Has anyone ever had anything like this before? I would normally automatically assume that it's something to do with the D-Link DSR-250N business router as one us can and one can't, but it's only happened since we changed ISP and it was fine for over a year before that!
I've been in touch with 1and1 and they have double checked our settings and still nothing.
EDIT: I've also tried changing my PC to static IP and it makes no difference.
