Outlook 2003 breaks Exchange 5.5?

[ocomik]

On Tuesday I upgraded my Office XP to Office 2003. Ever since this
upgrade I've been unable to access my Exchange 5.5 SP4 server. I have
tried a multitude of methods to get this resolved and have been
unsuccessful. I have a similar workstation still runing Office XP and
it is not having any problems.

Here's the details.

The current message I'm now receiving is: (Sorry for lack of specifics
but I'm not in front of that machine)

Unable to locate user name in the address book (or something like
that)

This happens when I attempt to setup my mail setting (Control
Panel->Mail->E-mail Accounts- Exchange).

Facts:

* Mail server is listed in the "host" file on the machine
* I can ping the mail server (ip and netbios name) as well as connect
to it via a share
* Mail server OS was upgraded (Thursday night) from NT 4 to Windows
2000
* I'm NOT running OWA
* Verified that the two known issues (Outlook 2003 Rules & CDO) with
Outlook 2003 and Exchange 5.5 did NOT appear applicable

Resolution Attempts: (All gleamed from various postings)

*Uninstalled all networking services, deleted Winsock and winsock2
keys in registry, reinstalled networking - NO LUCK
*Also re-performed the afforementioned steps and did a "Clean" boot. -
NO LUCK
*On the mail server removed the user account from the Administrators
group - NO LUCK
*Removed and re-installed the E-mail account (Control Panel-Mail) - NO
LUCK
*Attempted to create a new profile (Control Panel-Mail)and tie it to
an Exchange account - NO LUCK
*Upgraded OS on mail server from Windows NT 4 server to Window 2000 -
NO LUCK
*Uninstalled Nortel VPN Client - NO LUCK
*Attempted to call Bill Gates - NO LUCK

I'm pretty sure I've listed most of the resolution attempts, many of
which I've tried multiple times.

At this point I have to believe that Office 2003 broke something as
Outlook XP/Exchange 5.5 was functioning just fine (and still is on my
other systems).

Any thoughts would be appreciated.

Thanks
Mike

Make sure that the alias in the alias field (properties of the mailbox) is
the same as the username you use to access the mailbox.

Example:

Login name: mconner -----------> alias should be: mconner as well (don't
include a domain name!!!)

I think this should work.

ps, This can also prevent problems with WebOutlook and pop3 access to you
server.
