SYMPTOMS
On a computer that is running Microsoft Mobile Information 2001 Server, you may experience all the following symptoms:  When a user tries to log on to Microsoft Outlook Mobile Access for Exchange 5.5, that user receives the following error message:

500 – Internal Server Error

Note Outlook Mobile Access for Exchange 5.5 is a component of Mobile Information 2001 Server. You log on by typing http:// /OMA55 on the device. If you restart Microsoft Internet Information Services (IIS), the next connection attempt to Outlook Mobile Access is successful. However, after about 20 minutes, the user who successfully connected to Outlook Mobile Access again receives the following error message:

500 – Internal Server Error

After the user receives this error message, no new connections can be made with Mobile Information 2001 Server. If you view the IIS log file, you notice information that is similar to the following:
