Some mailboxes can not access OWA

I have exchange 2k3 running with OWA, out of about 30 mailboxes they can all access by logging into web interface but there are 3 users who can not log in, it looks as if their password is wrong but it's not?

Any ideas?

Did you checked the users permission in ADUC ?
Go to ADUC->user's properties-> Exchange Features Tab. Make sure that the users have permissions to access the OWA Protocol.
 
If still unresolved, do post the error here.

cheers !!

Hi andrew_2706,
Are all your domain controllers replicating correctly?

This usually means that the affected users do not have an email address in the same domain as everyone else.  It seems strange, but the default OWA installation can only access mailboxes in the Primary SMTP domain (in the Default Recip Policy).  If the affected users don't have an email address in this domain, you will need to add such an address to their accounts.  It doesn't have to be their primary SMTP address, though - it just needs to be in the list.

did you try using domain/username for authenticating?

I have checked:
All domain controllers are replicating correctly and up to date.
The users permissions are set to enable in the ADUC.
The Users have the correct email address on the correct domain.

Just tried changing the authentication from ESM but its greyed out in the OWA access tab?

Sorry, was in the wrong window for the OWA access, in now, the anon access is ticked, basic auth is ticked and the digest and integrated boxes are unticked?

Which folder were you checking for authentication?

The only folder that should have anonymous authentication enabled is /exchweb. No others should have anonymous access enabled.

What happens when they try to log in?  Any error messages displayed?  Does the logon box keep popping up?  Do you use Forms-based Auth?  If so, does it help if you turn it off temporarily?

It just pops up the login box time after time and then after 3 attempts it says Error: Access is Denied.
I'm not using forms based auth.

I'm pretty sure that if it isn't accepting the logon, then either the credentials are wrong (but you already checked this) or you are running Win2000 server (hence IIS5) with Basic Auth and the users don't have the logon locally right on the OWA server.  I'm not sure why this would affect only a few users - perhaps you have a security group for your OWA users.  Try turning off Basic for a while, and using Integrated, and see if it makes any diff.

It was in AD, Accounts Tab, Log On To Option, was restricted to logging on to their own pc only.

Thanks for all your help - it was a right nightmare!
