    Error message:

    The attempt to upload the attachment failed due to its filetype.



    Situation may arise, where Service Desk disallows a certain file upload, even though that particular file extension already appears as whitelisted in Configuration Center file upload policy.



    Known Problem 6869 - File Whitelist is case sensitive


    Solution / Workaround:

    For the whitelist to work on all files with different case variation of the extension, all allowed file extensions and their case types need to be added (8 entries per 3 character file extension). So for example to whitelist all .jpg files, you have to add all case variations of the extension to the whitelist, like this:

    This was fixed in version 2018.1, where the whitelist is no longer case sensitive.
