Mimetype to file extension mapping: NOT OK on IIS 8.5

[maximvd]

I recently installed Roundcube on my server.
Sending and receiving mails works fine but when I installed Roundcube I've got the follow error: Mimetype to file extension mapping: NOT OK
The server is running MS Server 2012 R2 with IIS 8.5 as webserver and hmailserver as mailserver.
Do I need to change something in the config or do I need to add Mimetypes to IIS?

Thanks, this fixed it for me.
Not sure why I hadn't found the page while searching for the error.

Hi,

Will be someone so kind to give the mime.types configuration instructions here, as the above link is not working anymore.

Thanks!

I figured it out. The "mime.types" file location has to be given as absolute path in the "config.inc.php" configuration file, example below:

$config['mime_types'] = 'c:\Inetpub\wwwroot\webmail\mime.types';
