Horde webmail : Content Encoding Error (content_encoding_error)

Scenario:

The content encoding error with horde webmail on windows installed server is not a common horde webmail issue. This happened on a windows server and error doesn’t occur for everyone, only for those from the Middle East. IIS has inbuilt HTTP compression. On trying to access the horde webmail it shows the Error as below,

Content Encoding Error (content_encoding_error)

Server response could not be decoded using encoding type returned by the server.
This is typically caused by a Web Site presenting a content encoding header of one type, and then encoding the data differently.

For assistance, contact your network support team.

The issue can be fixed by editing the horde webmail configuration file.

The Horde configuration file ‘conf.php’ on the windows server located at DriveLetter:\Inetpub\vhosts\webmail\horde\config\conf. PHP (Driveletter can be C or D. If D, its a good web host with good planning :D)

Once you found the configuration file,

Search for the following lines in that config file:
$conf[‘compress_pages’] = true;

Change it into:
$conf[‘compress_pages’] = false;

Now Save the horde config file & restart the webmail client (I mean IIS here) and try to access the webmail. If you still facing issues please reply back and we are happy to help you 🙂
