Missing spaces between words

Help! when I email my word 2013 documents over to other people ( who may not have the same version of word as me) it compresses certain words together.

The document reads perfectly on the version on-screen that I send, but when they receive them, these random errors occur that omit spaces in certain sentences and join 2 words together for some reason. nothing comes up on any checks i do?

Try the following and see if it makes any difference.

1. In the required document do this:-

Office Button (I think that this is File in the 2013 version).

Word Options (I think that this is towards the lower left hand corner in the 2013 version and may only be called Options).

The:-

Word Options

 - window should open.

2. In the:-

Word Options

 - window click on:-

Save

 - (on the left hand side) then, on the right hand side, in the section called:-

Preserve fidelity when sharing this document

 - make sure that your document name appears correctly in the drop down field and then make sure that there are ticks (check marks) in the following 3 boxes:-

Embed fonts in the file

Embed only the character used in the document (best for reducing file size)

Do not embed common system fonts

 - then (still in the Word Options window) click:-

OK

3. Save your document and send it to the recipient.
