I work in a company which uses a Remote Desktop Solution from a Windows 2003 which connects to an exchange server run by 1and1.
For some reason on the bottom right corner of the screen, 1/2 times a day our users see an outlook icon with a red " ! " on it. At the same time a message appears saying that outlook is trying to connect to the server. Outlook then goes grey saying "unable to connect to exchange server". Does anyone know why this is happening? I know the 1and1 server is in the US and our users are in the UK - but surely that shouldn't matter??
