It's possible that the device's browser is configured to use a proxy
server somewhere that does not fully support authenticated sessions,
and keeps forgetting the credentials. See if it has a proxy server
configured in its preferences.

You may also need to check your IIS logs. Look for the initial GET
request to /Exchange. It should result in a 401 response, which
causes the browser to ask for credentials. Once the browser has the
credentials, then it shouldn't ask for them again, and every other
request into the /Exchange VDir should get a 200 response (although
sometimes there is a 401 followed immediately by the 200). If you see
lots of requests getting a 401, then followed by a 200 a few seconds
later (i.e. the time required to type in the credentials again), then
you should see where the problem is.
