I cannot open my Microsoft Outlook?

Hi,

The connection to Microsoft Exchange is unavailable is a common symptoms if caused by registry issue. Once installed, and you get this message when opening, you only have 2 options either to click OK or close the pop-up.

If you choose to click, then the dialog box for Microsoft Exchange will pop-up. Then the Outlook 2007 Start Wizard starts, the options you can choose is to Add New e-mail Account. You will have then need to follow the steps, click next until you've created an account successfully.

What needs to be done if you get that message is to remove some registry entry. Administrator has to modify the policy and you'll need to contact your domain administrator.  

You will need to remove the following registry.

* Go to Start, look for start search and type regedit and press enter or click OK.
* Look for the following and remove it. 

• HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\AutoDiscover
