Hello

I know there are a few solutions to this but I dont seem to be able to find one that helps. I have a SBS2003 Server and we are unable to open public folders using OWA, login and access to the users folders works fine. I have currently running the default web site on port 3000 and I have changed this back to port 80 which made no difference.

I am unable to open the public folders in ESM unless I change the default port back to 80 , if i do this I can view the public folders in ESM without a problem.

However I still can not open them from OWA any body any suggestions ??

many thanks

OWA doesn't like using anything other than port 80/443 for access, so moving the site back to the default port was the correct thing to do.

If you use IE on the server itself and browse to http://serveranme/public does the same thing happen?

I suspect that something is wrong with the virtual folders - application pool in correct, something like that. You may find that resetting the virtual directories will work.

Yes, this is usually an Application Pool problem.  Have a look at the properties of the Exchange Virtual Directory in IIS Manager, and see which Application Pool it is configured to use.  Then, have a look at the properties of the Public VDir, and make sure that it is configured to use the same one.  If the drop-down list is not enabled, just click the Create button.

Many thanks for your prompt repsonses

I have checked the properties as suggested by Lee and they appear to be the same, when I browse to the server and attempt to look at the public folders I get the same error.

I have as yet not reset the virtual directories as I note the store has to be restarted ..................

Is this a definate step forward ?

thanks

Not so much a step forward, but it has (unfortunately) eliminated the most common reason for the error.  Is anything written to the server's Event Logs (Application or Security) when you try to access your PFs in OWA?

There does not seem to be anything in any of the logs relating to the PF's I guess I will have to try and reset them when the mailboxes are not in use

I think that's your next best bet, when things are quiet. Remember that you only need to delete the Public VDir when you do it. No point in resetting the other Exchange VDirs if they work okay.
