Outlook 2007 stays "disconnected"
Sometimes I do these things just to try them out... For example, I recently got a new laptop and decided to install Vista 64-bit on it and Office 2007. I have the IT team reporting to me so it makes sense that I try out some stuff and I tend to be able to help myself enough that I don't cause a drain on their resources. I decided a while ago not to upgrade our internal systems to Vista or Office 2007 for a while yet. Vista partly because of the hardware requirements which we can't meet, partly because it is still flaky - even after service pack 1. Office 2007 because the UI is so different that it will just cause a lot of calls to the IT Helpdesk and I can't see any real benefits in the new version - it is mainly window dressing with little substance.
But I digress... One of the problems I have had with my setup is that often when I switch between the wireless and the wired network (many times a day - the curse of being in and out of meetings) Outlook 2007 will go into "disconnected" mode and will stubbornly stay there. Normally a reboot will sort it out but not today so I decided to do a bit of digging. It turns out this is well-known problem in Outlook 2007 and I have seen reports back from May 2007 - but still no fix from Microsoft. They do have this article but the "solution" in there doesn't work and is in any case unrelated IMHO (it only deals with RPC, I have the same problem with pure HTTP)...
However, some kind soul on a message board revealed the secret: you need to run "ipconfig /dnsflush" in a command window and it sorts it out. Mind you, you need to do this each time you see the problem. Would be nice to see a fix to this problem...
