Outlook Office 365 for Windows 10
Expected Result
I've been using the fantastic code from @M-J-Robbins below, which provides inline horizontal spacing
<i style="letter-spacing:50px;mso-font-width:-100%;display:inline-block;width:50px"> </i>
Actual Result
With limited support for letter-spacing in Outlook Office 365, this spacing no longer renders.
Further information please see the support ticket here - https://learn.microsoft.com/en-us/answers/questions/4677959/outlook-desktop-style-limitation-letter-spacing
Alternative Options
The mso-font-width spacing from Mark's CTA button code still works (thanks again Mark)
I've found the following is a close work around
<i style="font:10px/10px auto;mso-font-width:500%;display:inline-block;width:50px"> </i>
The font styling is not required, you can use your em spacing based on default font-size, but I find resetting to a 10 base easier to work with for just this spacing code.
