I get the error message "Filename or Catalog name is invalid", what to do?

Microsoft released updates for Office that creeates error messges once you drag and drop emails in lime.

It is possible to remove those error messages, and the document will be saved correctly in lime.

The update KB3115158 is what has caused the error and you can read moe about it at Microsoft's webpage: https://support.microsoft.com/en-gb/help/3115158/june-7,-2016,-update-for-outlook-2013-kb3115158

We are examining the problem to see how to fix it. Today, you can only do two things to remove the error message: uninstall the update or just "click the error message away".
