RE: OWA Calendar loading error



Hi Nancy,

Thanks for posting here.

>From your post, I understand that you have some users cannot load the 
shared sales calendar and only displaying "errors on page" in the status 
bar. You refer the following knowledge base article:

http://support.microsoft.com/?id=842470

but the issue hasn't been solved. If I am off-base, please feel free to let 
me know.

On a server that is running Microsoft Windows Small Business Server 2003 
and Microsoft Internet Information Services (IIS) 6.0, static files that 
are compressed may become corrupted and may include content from other 
files on the Web server. If this behavior occurs, the page that is returned 
to the client is not rendered correctly. An access violation may also 
occur. This problem can affect Outlook Web Access (OWA) users. The problem 
may cause various script errors to be returned in the OWA pages, or the 
problem may cause pages to stop responding (hang) when the pages load.

Based on my experiences, I suggest you disable the compression on the 
Exchange Virtual Server. The following steps for Windows Small Business 
Server 2003:
1. On the Windows Small Business Server 2003, in Exchange System Manager, 
expand Administrative Groups if administrative groups are enabled, expand 
Servers.
2. Expand Protocols, expand HTTP, right-click Exchange Virtual Server, and 
then select Properties.
3. Select the Settings tab, and then select the check box next to Enable 
Forms Based Authentication.
4. In the drop-down menu next to Compression, select the None to use.
5. Click OK.

Additional, you can install the following Hot-fix to solve this issue:

FIX: IIS 6.0 compression corruption causes access violations

http://support.microsoft.com/kb/831464/en-us

If you cannot install this Hot-fix 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 IIS 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.

I hope the above information helps.

Have a nice day.

Best Regards,
