One delivery method we use to equip clients with EDMs is the save as Outlook Template (.OFT)

Though this strips out responsive elements its always seemed to be a solution that works as for as allowing them to send out a designed email, and maintain style and layout at the other end.

Now in comes Outlook 365/2016 and we're seeing a big problem.

The coding to get around 365's issues is kept in any OFT saved from it. And then forced into the email when opened in other mail clients.

And vise versa with any OFT saved in earlier versions, not working in 365.

The universality of the template working across outlook on multiple platforms seems to be lost.

Has anyone else noticed this? Are you aware of work arounds/fixes?
