C# Exchange Server Connection

Question

We have a windows service connecting our exchange web service and retrieving mail items and processing them. Until two days ago it worked fine for 2 years even if the exchange server upgraded 2007 to 2010. But two days ago a strange problem started.

When we use OWA inbox is full of email messages. When we try to get emails using web service no email item is returned

What would cause such a behaviour?

Thanks

Cause And Solution: The problem caused by the many email messages(in our case about 4700) in the inbox. When you clean your inbox web service will work as expected again.
