On some networks, Windows Vista® may not allow you to download large email messages or file attachments to a POP3 account. Instead, you get a message that the server has timed out.
Until Microsoft releases a patch or fix for this issue, you can disable autotuning.
To Disable Autotuning in Windows Vista
- From the Start menu, select All Programs > Accessories.
- In the Accessories list, right-click on Command Prompt and select Run as Administrator.
- At the command prompt, type netsh interface tcp set global autotuninglevel=disable and press Enter.
- When the command prompt returns confirmation of OK, close the command prompt window.
You should now be able to download your email in Windows Vista without issues.
