Question : OL2k3: Unable to open your default e-mail folders. The information store could not be opened.

I work for a small business.  

My computer runs Windows Vista Business SP1.  

I have Office Outlook 2003 SP3 on my computer.  

My email server is Exchange 2003.  

Exchange 2003 runs on Windows Server 2003 SR2 (not SBS).  This server is a domain controller for our network.  

When I open Outlook, I get this error: "Unable to open your default e-mail folders.  The information store could not be opened. "

None of my co-workers get this error, Outlook works fine for them.  

Outlook used to work fine for me.

Here is what happened:  One day, I wanted to open several old PST files from before we migrated to Exchange (we were POP3 before).  I wanted to create a separate mail profile for each PST so I could switch between them without cluttering up my own Mailbox.  When I was done with these PST files, I started to delete their mail profiles one by one.  While I was doing this, I accidentally deleted my own mail profile.  Not a problem, I thought.  I recreated my mail profile no problem, but now I get the above error whenever I try to open Outlook.  

I can access OWA.  

I can set up my email account in Outlook on other computers.  

I have tried deleting and recreating my mail profile (Control Panel > Mail) on my computer.  

I have tried repairing Office 2003.

I have tried reinstalling Office 2003.

I have tried uninstalling and reinstalling Office 2003.

Please tell me how to fix my problem.

Thanks for your solutions takenoco but I'm going to have to chalk this one up as unresolved.  

I'll tell you one thing that works...  I removed it from my Office installation, downloaded the Office 2007 trial, installed Outlook 2007, and it works.  So I'm just going to buy OL2k7.
