Hi, I'm suffering a very odd issue that I'm finding hard to solve!

The basic issue is that in a coupl eof random places in my email random spaces are being added within a word i.e.:

How to be more than just another accountant.

becomes:

How to be m ore than just another accountant.

Now, the thing that makes this hard to understand is:

1) This only happends when I send the message via a specific ESP (Pure)
2) This only seems to affect Outlook 2016 (Mac - I don't have a live PC version to test)
3) This doesn't appear in the preview renders I get from the ESP - maybe it's a bug/issue with our exact version of the app?!

Here's a bit of sample code that it affects:

    <p style="font-size: 16px;color: #666666;font-family: Open Sans, Arial, sans-serif;font-weight: 300;margin: 10px 0 10px 0px;line-height: 24px;-ms-text-size-adjust: 100%;-webkit-text-size-adjust: 100%;">The afternoon will consist of Raj Birk, our Sales Consultant who will be giving a full overview of the range of products available to a practitioner and we wrap up with motivational speaker Mark Lee on 'How to be more than just another accountant'.</p><p style="font-size: 16px;color: #666666;font-family: Open Sans, Arial, sans-serif;font-weight: 300;margin: 10px 0 10px 0px;line-height: 24px;-ms-text-size-adjust: 100%;-webkit-text-size-adjust: 100%;">

So my queston is, has anyone seen this happen before?
