Outlook 2010 on dual boot system

I am running a dual boot system with Vista Ultimate on Drive 0, this drive also has Outlook 2007 running. On Drive 1, I installed a 1GB HD and Win 7 Pro plus I installed Office 2010 (so I have Office 2007 with Outlook 2007 running on drive 0 and Office 2010 with Outlook 2010 running on drive 1).

I clean installed Win 7 on its own partition and installed Outlook 2010. Outlook worked fine when I set it up and its data files were on C:\ . Since my data files are on a different partition (M:\) I changed "Documents", "Music" and etc to the M:\ partition.
After, when I opened Outlook a window opened and let me change the drive letters from C:\ to M:\, the problem is that now I get an error 0x8004010F "Outlook data file cannot be accessed" when I open Outlook. I can not figure out a way to find the window again that allows me to set the Data File Location.
I read somewhere that it is best to leave it on C:\ but I can't find a way to do that.
My internet service is Sympatico and they can't help me - told me to uninstall Outlook 2010 and re-install it, but I don't see how that will help. Any one else run into this problem.

for your actual problem, i don't know what to say, but to get to your data file, try going to control panel, there should be some thing called "mail" over ther, click it, and a window will open up, the middle option is data files.

Hard to believe but Outlook 2010 fixed itself. I did't have time to play around with it and a week or so later I opened it and it was working. It installed the files to the directory I set up for Outlook 2010. Wonders never seize.
