Windows 7: 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.

Haven't tried this myself, but I was asking about installing Office 2010 with Office 2007 remaining, and I was told that Office 2010 would automatically replace the instance of Outlook 2007 with Outlook 2010. The poster claimed that with Outlook "there can be only one".

If you're trying to run two instances of Outlook 2010, that might be the basic problem.

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.
