Microsoft Outlook Error – “Cannot start Microsoft Office Outlook. Cannot open the Outlook window.”

I have had the same problem as egrand (trying to run in Vista the fix as posted).

THANK YOU SO MUCH! The spacing worked… I have been working on this for hours including deleteing registry and nothing worked. THANK YOU!!!

Awesome, easy fix for a perplexing problem. Thank you.

Thanks, that worked perfectly…you need the space though!

Thank you this worked – with the space. Why does this suddenly happen though? Bit worrying. It followed a Windows update….

Thanks, great tip about the space in the command line, it doesn’t work without it.

Fantastic. Worked for me too. I was a bit worried I would lose all my conatcts, but I didnt. Thanks.

Thank you verry verry much

Thanks, finally a solution that works. I’m very grateful.

Thank you very much it worked from the get go!

great stuff – excellent work fellas!

This fix worked for me except my contact list is missing. Any suggestions on where to find it?

Thank You so much!
Microsoft qouted me 5 hours at $89 per hour to fix this. I was about to the point of paying it when I found this.

Myrna: I tried that on Win7 and it worked.

However, I observed that all my previously configured search foloders and favorites folders are gone. My configuration for “Mail” view has been resetted to initial as well (I had customized it as per my convenience).

Although, these are minor issues as compared to the original one but I am really curious about what went wrong and what this command did to fix it.

Thanks,
Kamran

worked for me too,.

Great tip about the space between. Used alternate program for weeks before discovering this site. Thanks again.

Thanks this worked for me you saved my life all my work is on my outlook Thanks so so much

Didn’t work for me XP with space blah blah, effing Microsoft

Yes worked fine for me too but I have to do it everytime I reboot – is there a way to make it a permanent fix?
Or is there something on my computer causing this to happen?
Outlook had been working fine previously and I’d hadn’t made any changes or added any new programs it just suddenly started doing this for no apparent reason.
Using new computer with windows 7

have been looking for solution for hours. THIS WORKS LIKE MAGIC!!!

Thanks for the info – fixed the problem her

Many thanks

Thanks so much, this worked great for me on Windows 7.

All the best,

It worked for me too, but I did it yesterday and today had the same “crash’. The computer went blue screen to “protect data loss”, when I rebooted I got that message in office 2007. “Couldn’t open the windows screen..” I ran the code suggested and it’s now working again, but the question is why is it happening repeatedly?

just a follow up to my previous post where i had the problem that i had to do the fix everytime i started up (new dell computer, windows 7) – it actually stopped doing that after about 5/6 times and is now a permanent fix, no idea why as i changed nothing, but great anyway, thanks again!

Thankyou , you helpend me a lot! And the information was very weel explicited

Worked brilliantly! Thank you.

This worked for me, thank you! Any ideas why this happens? It occurred on a new computer, and Outlook was only activated today. Outlook was working fine during the day, and the error occurred when restarting Outlook after the computer was idle for a while. Very frustrating, very thankful for your post!

Just a little tip on errors like this. When in doubt, run process monitor from sysinternals. That will reveal the problem in many cases.

Great, It worked. I waited for 2-3 days to get the problem fixed.Thank you very much.

Thanks – worked a treat!

Thanks a lot.. It worked fine..

Fantastic. ran the command and bingo!!! All is good. Thank you.

Thank you Thank you! Easy easy fix. You will be my first stop for help from now on!

thanks, It helped me.

I have Vista and I get no error message, but Outlook 2010 simply doesn’t open after clicking on the icon. The little circle thingy spins around for a few seconds, as if preparing to open, but then it stops and nothing happens. I’m loathe to mess with registry keys because I’m not that geeky. Is there a way to get Outlook 2010 running?

Your instructions worked perfect. Thanks for the extra one about enabling ‘Run” You’re awesome!

“Outlook.exe /resetnavpane” worked for me.Thanks
