I have a user who has a "problem" with his PDA. We have contacted the phone
provider who is basically saying its not their problem and user is at his
wits end.

I have also posted to MS Exchange Server Newsgroups and they suggested
posting here so hopefully someone can help.

The user has an XDA Mini S using Windows Mobile 5.
He also has an HP Ipaq using Windows 2003 Mobile and has no issues at all
with the HP Ipaq and connects to the same exchange server.

On the XDA Mini S Push mail works fine. OMA also works fine.
When the user uses a PC and connects to the exchange server, OWA also works
fine.
However he wants to use OWA access from his PDA and this is where he is
experiencing difficulties.

We have explained to him that OWA is not suited to the small screen of the
XDA mini but our client is querying why it sometimes works and when he tries
to use it (his choice) it starts to download and then prompts him for
password again, downloads a bit more and then prompts for password again
until eventually he can see email.

Can anyone help here.
Thanks

JK

Copy of post from MS Exchange newgroup below.

"Thanks for posting here.

From your post, my understanding on this issue is: You have one PPC XDA
mini S using Windows Mobile 5, by which he cannot access Exchange mailbox
by OWA. If I'm off base, please feel free to let me know.

First of all, you are right that we don't recommend using PPC to access
Exchange mailbox by OWA; this is because OWA is not designed for mobile
device access and downloading OWA interface will take high bandwidth. It is
strongly suggested to use OMA and ActiveSync to access Exchange mailbox.

However, technically it should always be possible to OWA access mailbox by
Mobile Device. Considering there is only one mobile device encountering
this issue, I am 100 percent sure Exchange Server is configured very well
and this must happen due to configuration of this specific PPC. Since our
newsgroup is only focusing on Exchange Server Side configuration, you may
need to contact Mobile Provider or post your question in PPC specific
newsgroup as below. "

It is correct that OWA is not suited to PDA use, but it should still
be possible. I would suggest checking the properties of your ExchWeb
Virtual Directory in IIS Manager. Look at the Directory Security
page, and make sure that Anonymous Access is enabled. It sounds like
the user is being asked to authenticate each time a supporting file
(like an image or an included script) is requested.

We have checked the ExchWeb Virtual Directory and Enable Anonymous Access is
selected. No other Authentication is enabled.
This user has no problems using Outlook Web Access from a PC only his PDA

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.
