Basically, you (or the software you were installing) switched your IIS site where OWA is installed into either a 32bit mode or ASP.NET 1.1. Since Exchange 2007 Outlook Web Access 2007 only runs on ASP.NET 2.0 in 64bit mode, you need to fix it back.

First, disable the 32bit mode for your web site. By default OWA goes into the Default Web Site context (0) so the following will take care of that:

cscript C:\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 0

Second, register ASP.NET 2.0 as the default framework for that web site:

C:\Windows\Microsoft.NET\Framework64\v2.0.50727>
aspnet_regiis.exe -i
Start installing ASP.NET (2.0.50727).
……………………………….
Finished installing ASP.NET (2.0.50727)

Restart IIS and you should be all set.

1. Start the Exchange Management Console.
2. In the console tree, expand Recipient Configuration, and then click Mailbox.
3. In the result pane, right-click the mailbox for which you want to configure mail forwarding and click Properties.
4. In <Mailbox> Properties, on the Mail Flow Settings tab, click Delivery Options, and then click Properties.
5. Click the Forward to check box. This enables the Browse button.
6. Click Browse to open the Select Recipient dialog box. Select the recipient to whom you want to forward messages, and then click OK.

   Note:
   By default, the dialog box displays all recipients that are in the current recipient scope that is specified in the Recipient Configuration node. To learn more about the recipient scope and its impact on the recipient work center, see Understanding Recipient Scope.

7. If you want incoming messages to be delivered to the mailbox as well as to the forwarding address configured, select the Deliver message to both forwarding address and mailbox check box. Clear this check box to forward all incoming messages without retaining copies in the mailbox.
8. Click OK to return to <Mailbox> Properties.
9. Click OK.
