SYMPTOMS
========

When you configure the Microsoft Exchange or Outlook client to connect to a
Microsoft Mail postoffice and set the client to check for new mail at a specific
interval greater than 10 minutes, you notice the Microsoft Mail postoffice is
polled and the Flag.glb file checked approximately every two minutes.

If you apply a network trace between the client and the server hosting the
Microsoft Mail postoffice, you see that every two minutes the client checks the
Flag.glb file and thus makes a network connection.

WORKAROUND
==========

For networks configured to do remote Domain Name Service via on-demand ISDN
dial-up, changing the network topology is typically the only workaround.

STATUS
======

This is by design.

The behavior of the client can prove to be unexpectedly very expensive for
networks that are configured with dial-up on-demand ISDN connections, especially
when outbound connections are expected to occur at greater time intervals.
