Troubleshooting OWA For PDA / OWA For WAP

When you are configuring your OWA For PDA installation, it is usually easier to use the Web browser that is installed on your PC. It is not, however, possible to do this with OWA For WAP since it does not produce an output that can be viewed using a standard Web browser. The WAP protocol uses WML documents which can only be displayed by a dedicated WAP browser.

Since it is not normally convenient to use a WAP 'phone during testing, I recommend using a PC WAP browser such as WinWAP. A time-limited demonstration version of WinWAP can be downloaded from www.winwap.org. The WAP viewer at www.wapsilon.com also works well, but since your OWA For WAP site is protected by authentication, you will have to log on each time you navigate to a different page.

If you see the Network Login dialog box three times, and then the login fails, your server may be authenticating you against its own User accounts instead of the network's. Try logging in with <DOMAIN_NAME>/<USERNAME> instead of just <USERNAME>, or verify the default Authentication Domain for the Virtual Directory in IIS manager.

Also (for Exchange 5.5), check that the 'Everyone' or 'Domain Users' group has the 'Log On Locally' right on your IIS server.

"This is a marker file generated by the precompilation tool, and should not be deleted!"
This is sometimes encountered when the application is installed in Windows Server 2008 (i.e. IIS7). It means that the installer was unable to convert the web directory to an application. You will need to find the owa-pda (or owa-wap) directory in IIS Manager, and manually convert it to an application.

404 - Page Not Found
This sometimes happens with the Exchange 2007 version of the application. It can be caused by the ASP.Net version not being correctly set in IIS Manager. Normally, this setting will be inherited from the Default Web Site, but if the DWS has no setting, then it will be necessary to look at the properties of the OWA-PDA or OWA-WAP Virtual Directory in IIS Manager, select the ASP.Net tab, and select v2 from the drop-down list.

• The user has supplied a non-existent mailbox name at the Mailbox Name page.
• The user has attempted to open a mailbox, but does not have the required permissions on it.
• You have installed the product on a member server, but the Default Authentication Domain is not correctly set in IIS Manager. If you have an account on the member server with the same name as your Domain account, you will be authenticated locally, but be unable to open you mailbox. Try logging in with DOMAIN\USERNAME instead of just USERNAME, or make sure that the Default Authentication Domain is set properly.
• This error can also be caused by the CDO 'Ambiguous Mailbox Alias' effect which is seen if there are two similarly named mailbox aliases present on the system. Try supplying the mailbox SMTP address, or the Display Name, instead of the Alias. You can supply any of these three at the Mailbox Name prompt on the login page.
• The mailbox is hidden from the GAL. Rare, but it happens!

• If you have been using Outlook 2003, it may have added extra fields to your Exchange Information Store that will cause unpatched versions of CDO to fail. Make sure that your server copy of CDO.DLL is the most recent version by doing this CDO version check . If you don't have the latest version, visit the Microsoft Web site and search for the latest CDO patch for your Exchange version.

[Collaboration Data Objects - [MAPI_E_NOT_INITIALIZED(80040605)]]

• The user does not have the required NTFS permissions on the MAPI working directory, or the working directory name is missing from the registry. Check the following registry key:
  
  HKLM\SOFTWARE\Microsoft\Windows Messaging Subsystem\ProfileDirectory
  
  If you change this value, you will need to restart IIS because MAPI will not read this key again once it has started.

• If you see this error when you first try to open a mailbox, make sure that the profile directory named in the previously mentioned ProfileDirectory key has actually been created on the server.
  

HTTP Error 403 403.1 Forbidden: Execute Access Forbidden

• Script access has been disabled for the Web Site or Virtual Directory at the IIS server.

• The site or virtual directory does not have Default.asp in its list of default documents. Please add Default.asp to the list using IIS Manager if it is missing.

The scripting language 'VBScript.Encode' is not found on the server.

• The server is unable to decrypt the encrypted ASP source code. This may happen if the server has an Internet Explorer version lower than v5.0 installed. Please contact me if you get this error and are unable to upgrade to IE5.
