Hello,
It may sound odd but, Is there a setup in Outlook 2010 or in the PC itself to connect Outlook through the Wi-Fi and not the LAN connection?
I am using an external subnet on my LAN for better internet whereas my Wi-Fi is within the domain network with shared slow internet (if I activate the LAN subnet, outlook will get disconnected coz it will try to go through the LAN public subnet that has priority 1. If I change N/W priority for Wi Fi (1) and LAN (2) then my browsing will go through the slow internet that exists on the Wi-fi, ...I wish if there's a tweak to 'just' force Outlook connection thru WiFi ?
