I think this is pretty good, but a lot of it is kinda awkwardly written. Example:
Writing emails isn't Ahmed's favorite thing to do. However, his years as not only researcher, but leader would all be for naught, if he hasn't already understood the importance of charisma. Mimicking would be his best bet.
(email)
It wasn't the prettiest sight. The email could deliver exactly what he wanted it to in just a couple of sentences, but he knows that it wouldn't get team T-1618 engaged enough to do good work.
You might be going overboard with prose like "would all be for naught." I would move the first paragraph and merge it with the one after the email. Have the email first, then describe how Ahmed feels about it.
(email)
Ahmed never liked writing long, dramatic emails, but he's learned from years of experience that there's nothing more effective at getting his team engaged than using words like "daunting" and "vital." Usually imitating/mimicking the weekly announcements from the regional director's office carried the sort of weight that could get people excited for a project. Maybe the RD was using the same strategy.
I wouldn't use what I wrote because I also went overboard (lol) but I think that sounds better at least.
