Activsync issue - HTTP/1.1 401 Unauthorised

Hi there,

I have ripped pretty much all of my hair out trying to work this out so

all help is greatly appreciated. I have read through posts on this
newsgroup, however, none seem to relate directly to the problem I am

I am running a Windows Standard 2003 server with Exchange 2003 SP2 and
IIS 6.0 with Windows Mobile 5.0 devices. This is the only server
involved in e-mail, I am not running a front/backend solution.

The device I am testing with is an Orange C600 on WM5.

I have the following locations in IIS:


I have been through MS articles regarding setting up the correct
security, I tried creating a exchange-oma directory and that was able
to view OWA with no problems (this has been removed now). I also tried

putting in the SMTPProxy registry entry, however, this does not seem to

make any difference (this has also been removed).

Worth mentioning is the users have multiple e-mail addresses. When you

view a users 'E-mail Addresses' tab in Active Directory there are 4
SMTP entires and one X400 entry. However, as you can see from the IIS
info (above) we only have one Exchange vitrual directory.

The actual problem is when a user does a Sync 'over-the-air' it checks
for changes and does the copy of e-mail (I am only trying to sync
e-mail at the moment, although it does do this very quickly!) but when
you check the e-mail on the mobile device there are no e-mails.

The error on the log file on the mobile device reports HTTP/1.1 401

The WWW-Authenticate is Basic realm="external IP"

There are no errors being reported in the Event Viewer on the Exchange

This is my first post so please ask if you require more information!

Thanks for your time!

I understood that this documentation would lead you to a working

You mention "only server involved with e-mail". It might be that the SBS
documentation helps more:

Hi Chris,

Thanks for your links, however, these do not resolve my issues.

Basically, the two problems I am having are:


HTTP/1.1 401 Unauthorised


Unexepected Exchange mailbox Server error: Server:[server.domain] User:

[user@domin] HTTP status code: [409]. Verify that the Exchange mailbox
server is working correctly

However, the phone does sync and reports e-mails are being copied over
but when you go into the inbox on the phone it's empty?!
