I just reformeated my computer and reinstalled everything and now when I start Outlook 2007 I get: "microsoft exchange is unavailable" or "Your Microsoft Exchange Server is unavailable" either way it won't let me go any further.

So, after Googling it I found this and it worked:

You can work around this problem by adding a DWORD value that is named DefConnectOpts to the following registry subkey:

HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\RPC

To add this DWORD value, follow these steps.

(http://support.microsoft.com/kb/322756/ ) How to back up and restore the registry in Windows

1. Click Start, click Run, type regedit in the Open box, and then click OK.

2. Locate and then click the following subkey:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\RPC

(Note: if RPC does not exist it’s no problem - just create the key by right-clicking on the “Outlook” folder name and selecting “New->Key…”. A key will be created and you should be able to just type “RPC” at that point to name it.)


3. On the Edit menu, point to New, and then click DWORD Value.

4. Type DefConnectOpts, and then press ENTER.

5. Right-click DefConnectOpts, and then click Modify.

6. In the Value data box, type 0, and then click OK.

7. Exit Registry Editor.

Now, start Outlook 2007 and it should open normally (may take a few seconds to make the connection and retreive messages, however.)

This worked for me.
