Outlook 2007 cannot connect to Exchange Server properly without default gateway


When we connect Outlook 2007 to Exchange Server, we may receive a variety of errors due to there being no default gateway set on the machine. Please refer to the following article for how to work around this issue.

 

Error messages when you try to connect Outlook 2007 to Exchange Server: “The action cannot be completed” or “Your Microsoft Exchange Server is unavailable” or “Cannot start Microsoft Office Outlook”

NOTE: Based on our analysis, this issue always occurs when a user tries to connect at home via RPC over HTTP. Since home PC’s ISP may not have default gateway set.

    I upgraded Office 2003 to Office 2007 on a Vista machine and encounter this issue. Reference to KB913843, I’m not able to locate the key. Does the article apply to Office 2007 on WinXP only? In Vista, I even create the key but the same issue still persists. Any suggestion?

    I have installed Outlook 2007 on Windows 2008 (I am going to be installing BES soon, hence the need for Outlook) and have the same issue in that the registry key doesnt exist and Outlook wont connect to my local subnet located windows 2008Exchange 2007 server using Outlook. OWA is fine. Problem with mine is that even with a DG it wont work. Anyone got any ideas please?

    This has nothing to do with a default gateway. However, running this fix it tool seems to fix the problem:
