Exchange organization has 4 back-end exchange servers and 1 front-end server. From the internet clients access front end server via an ISA server. Using outlook express clients can successfully connect to the front end server using POP3. When a client fails to connect when using a PDA provided by Sprint Model PPC6700. The error code is 0x274d. Just want to make clear. Outlook express connects properly, which I infer that the ISA and Exchange server is setup properly to use POP3. It is just this PDA which returns the error.
I have not been able to find anything about this error on the microsoft support site or by google.
