Error Getting access to OWA, exchange 2007
After restart the server i got the following error trying getting access to owa: Server Error in '/owa' Application. Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.UnauthorizedAccessException: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access. Please Help

Hi, Please try to access the public web, such as and see if the issue persists. If the error does not happen, the problem should reside in the OWA virtual directory. Please follow these steps to check the permission settings for OWA: 1. Open IIS, right click OWA and choose Permission. 2. Make sure that Authenticated Users have read permission of this folder.
