I will try to keep this is as simple and concise as possible, as it is somewhat confusing to describe.

My company uses a specific format for 90% of the emails we send out in Outlook. most of the messages are replies (copies of the majority of the original messages) with some changes in details: ie updated times and dates of events. Our problem is that when we reply all to an earlier email (on a separate machine) the format is off. generally nothing aligns as our original format. Sometimes the font changes as well. It becomes very time consuming attempting to re-align everything, and a 1 minute email, turns into a half-hour event. This is also almost always the case when we reply via smartphone.
HELP!!!

Note: The only time I have noticed that the formatting remains unaltered, is if "User A" replies to an earlier email, sent by "user A" (using same computer). Im not sure which version of windows/outlook every machine is running, but i am sure they vary.
