Outlook 2010 disconnects due to NIC card properties
Posted on 2013-02-01
Hi - I have a really odd problem with our Outlook 2010/Exchange in the office. At random intervals, some users get disconnected on Outlook 2010 and are asked for their password. When password is entered it is not accepted.
I am not sure why this is happening although I can fix it by adjusting the network interface card properties for the machine that is experiencing the problem.
The fix is as follows:
Close Outlook 2010
Go to Device Manager and select properties for Network Adaptor
Disable "Magic Packet" or any wake-on-lan features.
Exit Device Manager and restart Outlook
The problem is then solved but it occasionally re-appears and then I have to run through those steps again. I've had 2 machines disconnect Outlook this morning.
Does anyone know what causes this issue?
