Ok..I’ve read «a lot» of articles on this topic but, none have resolved my issue so far. Authentication fails for External OWA back into a lab for Exchange 2010/2007 with a 401 error. I’m publishing through 2010 TMG server. Internal works fine for 2010 and
2007 and redirects to my legacy 2007 CAS (Had to use manual redirection though).
The environment is a cross forest trust with users in one forest accessing their mailboxes in another forest (Linked mailboxes). Users access a Website via
HTTP (http://www.mail.domain.com) which is published as the OWA root and then click on a link to access the 2010 CAS (https://mail.domain.com). They
can get
to the OWA root web page in the lab but, accessing the actual OWA link fails to authenticate and generates the 401 error.
OWA 2010 Publishg rule is as follows:
Action — Allow
From — anywhere
TO — mail.domain.com
10.0.0.20
Forward original host header
Requests appear to come from TMG
Traffic — HTTPS
Public Name- Requests for the following web sites/mail.domain.com
Paths — /public/*;/OWA/*;/exchweb/*;/Exchange/*;/ECP/*
Authentication Delegation — Basic
Users — All Authenticated
Listener Rule is as follows:
Networks — External
Connections — Enable SSL /443
Certificate — *.domain.com assigned to the TMG server
Authentication — Forms>Advanced — SSL client certificate timeout — 300 sec.
SSO — not turned on.
On the 2010 CAS IIS properties:
The web root is setup on the 2010 CAS as a seperate site with a seperate IP:
http:www.mail.domain.com / 10.0.0.30 / Only port 80 is bound to the site.Authentication is anonymous only. An index.asp file is referenced that provides a
link to https://mail.domain.com.
The
Any help would be greatly appreciated.
Newer 2010 Exchanger server with an OWA redirect. When trying to access OWA with http://mail.xxxx.com or https://mail.xxxx.com I instantly get an: 401 — Unauthorized: Access is denied due to invalid credentials. Using https://mail.xxxx.com/owa still works.
I’ve done 2010 Exchange installs before with OWA redirection successfully in the past. I’ve researched this error to no avail. Please assist, thanks in advance.

OWA on exchange 2010 gives me the following error message 401 — Unauthorized: Access is denied due to invalid credentials. this exchange server is installed in an environment
which already has an exchange server 2003 (coexistence)At first I had the authentication set to «use form-based authentication) I would see the login page but it would not take my password,
-I tried using domain\UID and
UID@domain-I tried using the mailbox which was created on exchange 2010 still did not work
Then I change the Authentication to «standard authentication» with the following setting «Integrated Windows authentication» and «basic authentication»
and now when I browse the OWA link i get 401 — Unauthorized: Access is denied due to invalid credentials.
can anyone help me troubleshoot this problem. thanks

I solve the problem, In IIS the basic authentication was not installed, I installed it and enabled it and now everything is okay

Hi guys.. I have setting my OWA in my server, but if i try to login as a user in the domain the error below comes out: ============== Begin of error =============== 401.3 Unauthorized: Unauthorized due to ACL on resource This error indicates that the credentials
passed by the client do not have access to the particular resource on the server. This resource could be either the page or file listed in the address line of the client, or it could be another file on the server that is needed to process the file listed on
the address line of the client. Please make a note of the entire address you were trying to access and then contact the Web server’s administrator to verify that you have permission to access the requested resource. =============== End of error ================
But if i login as administrator account in the domain there is no error and the user login has successfully entered the OWA to access the email.. why ? can you give me a clue ? i have been trying to set it up for a days but i could not find the answer..
Thanks. Regards, Adhi.
