Copy and paste from word or excel in ckeditor, the formating is losing

[Ravi]

Hi Team, We use firfox 38.3.0 version and in our application we have CKEDITOR, the version is 3.6.2.Our end users sends mails to external clients by using CKEDITOR version. Below issues are we are facing

1. if we select font size as 16, after reaching the email to outlook, the font size shoing as 11.
2. copy paste from word doc into ckeditor, the format is missing.

we used the "pastefromword" plug-in. defined the setting is config.js file.

config.pasteFromWordPromptCleanup = false;
config.pasteFromWordRemoveFontStyles = false;
config.pasteFromWordRemoveStyles = false;
config.pasteFromWordNumberedHeadingToList = true;

deping up on the data, the copy and paste is working fine(tables, bold, color..etc) . but in most of the cases , the formating is missing in ckeditor and also in outlook after sending the email.

3. in one case, the font-family is showing as "Symbol" if we copy and paste data from word doc into ckeditor.

any suggestion and solution to resolve formating issue from word doc into ckeditor.
