Installing a SharePoint Site breaks OMA

At our organisation we use OMA heavily and we recently purchased SharePoint
Portal Server

When the default website was extended with SharePoint and all the
directories were excluded from being managed by SharePoint it caused Outlook
Mobile Access along with all other .net framework based web applications to
fail.

It appears to have changed some security settings.

I know the solution is probably simple but I cannot find an answer after
having searched the knowledge base etc.

Please can someone help
Thanks
Robin

N.B After disabling custom errors, the following error is displayed:
