After reading many many blogs and searching through MSN knowledgebase finally I was able to resolve the issue myself. It seems to a very common issue that doesn’t always have the same solution. Here are couple of useful ones:

My problem was that I’m using Windows 7 64-bit as workstation on my laptop and XP SP3 on a desktop and they’re both running outlook. I didn’t have the problem on the desktop but the problem drove me crazy on the Windows 7. The problem started when i rebooted the machine outside the network and it longer found itself to be the same domain that is currently running on the network. Even logging on using VPN to machine to servers gave me a hassle when using server shared drives. I had to authenticate all over.

On our network we run our exchange on one domain and everything else on another domain and then we use exchange tasks to associate the account with an external account. After going through all suggestions I went to the properties of my user on Exchange server, Exchange General, Delivery Options and added my exchange domain user to the list of users who have access to the account and then it worked fine. This tells me that all this time I was trying to send email as the exchange user and not my main domain account.

very odd and frustrating issue!
