RE: OWA problems

Hi Dave,

Thanks for using the SBS newsgroup!

For your description, I understand that the issue is: OWA users can not
access mails and got http 405 error; and users can not use outlook to read
mail. If I am off base, please don't hesitate to let me know.

Based on my research, this issue may related to the compression setting on
Exchange 2003. I therefore suggest that you disable the compression.
Exchange OWA compression settings used to reduce network bandwidth. To do
so:

1. Start Exchange System Manager.
2. Expand and navigate to Protocols/HTTP (Administrative Groups -> Servers
-> yourservername -> Protocols -> HTTP).
3. Highlight Exchange Virtual Server, and open its Properties.
4. On the Settings tab, set the compression level to "None". If you have
not enabled the Forms Based Authentication, the option is grey.
5. Restart the following services:

- Microsoft Exchange System Attendant service
- IIS Admin Service

And then try to test again to see if the issue be fixed.

If the issue persists, the issue should be caused by IIS 6.0 compression
corruption, please refer to the following KB article to get hotfix to try
to resolve the issue:

FIX: IIS 6.0 compression corruption causes access violations
http://support.microsoft.com/default.aspx?scid=KB;EN-US;831464

*Note: You must restart your computer after you apply this hotfix.

If you cannot install this hotfix immediately, you may be able to
temporarily work around this problem by deleting the cached, compressed
copy of the affected file or files on the IIS server. By default, the
compressed file is located the following folder:
%windir%\IIS Temporary Compressed Files
This temporary directory location can be changed in the IIS Manager on the
Service tab in the Web Sites property ***.

To delete the cached files on the server, follow these steps:

1. Open the IIS Temporary Compressed Files folder.

The default path is %windows%\IIS Temporary Compressed Files.
2. Delete all the files in this folder.
3. At a command prompt, enter IISReset to restart all IIS services.

You may also have to delete the cached files on the client to make sure
that the corrupted files from the cache are not used. To do this, follow
these steps:
1. In Internet Explorer, click Internet Options on the Tools menu.
2. Click the General tab, and then click Delete Files.
3. Click OK.

If you are experiencing the symptoms described in the Symptoms section and
you have already installed Microsoft Windows Server 2003 Service Pack1
(SP1), or if you continue to experience the problem the symptoms described
in the Symptoms section after you apply the recommended pre-SP1 hotfix as
an additional action, delete all the files in the %windir%\IIS Temporary
compressed files folder as above steps.

I appreciate your time. I am happy to be assistance of you and look forward
to your reply!

Have a nice day!

Sincerely,

Jenny Wu
