I also have Outlook 2007 running and had the same error occurring. I'm not
running Vista but XP, but your suggestion to run Outlook.exe /resetnavpane
fixed it instantly. My system was running fine prior. The only thing was my
system had been taken down the last few days by power outages.

Thank you for posting this as I was not looking forward to all the other
suggestions that numerous others had tried.

Ok mate, I got it going...

Now this is a bit vague because I was trying to reset everything but the
process was:

1) Removed my ost (yes I'm using exchange) - well I renamed it
outlook.ost.old in C:\Users\USERNAME\AppData\Local\Microsoft\Outlook and
renamed my archive folder in C:\Documents and Settings\USERNAME\Local
Settings\Application Data\Microsoft\Outlook
2) Uninstalled all addins
3) found this page and started playing with no success
http://www.microsoft.com/communities...6865&p=1&ntf=1

... UNTIL I ran Outlook.exe /resetnavpane

Clears and regenerates the Navigation Pane for the current profile. Removes
all Shortcuts and Favorite Folders. Has the same effect as deleting
profilename.xml in your user directory.

After this, I was able to get back into outlook!

The only clue as to why this may have worked is because when I got the
problem, another XML file on my machine (required to run one of my
development programs) had also become corrupted - I can only guess that
perhaps the profilename.xml possibly became corrupted in a similar kind of
way...

I'm really sorry I cannot give any more detail: I've been effectively
button-mashing (ok, running varous command-line switches mainly to do with
"cleaning" stuff) but it only worked once this switch was executed.

It may be a combination or specifically this switch, but I hope this
provides a little bit of a clue...

Since I have a second machine, I have been living with the issue on my Vista
machine. I have not heard any 'fixes' although it seems there are more
reports like ours.

Resisting a complete rebuild ...

Unable to start Outlook; rcv dialog "Cannot Start Microsoft Office Outlook;

I have attempted several published fixes including Scanpst,
DeleteOutlookProfiles, running Outlook with /safe switch (same error),
uninstall/reinstall Outlook, turning Norton 2009 off during my process, etc.

On reinstall (after running DeleteOutlookProfiles), I create a new profile
and a new Outlook PST ... still receive the "cannot open..." error.

Any further suggestions - hopefully short of resorting to my recovery image?

Thanks,
