To me this is the #1 reason this looks fake - nobody uses Mail for Windows, it probably doesn't support the security features available in O365, feels totally wrong for someone at MS.
During the pandemic I built a number of simple indoor solar systems, setting panels in the lower part of my windows (I keep the shades open at the top) and hooking up to either a homegrown controller/battery/inverter system or a jackery.
The jackery is roughly 30% more expensive but feels a lot less fragile than my homemade stuff, and I've moved all my device charging (tablet/phone/power tool battery) charging over to these systems.
It was a fun project! Cabling is always the part that sneaks up on you so make sure to plan out the cabling / what plug types you want / crimp or buy / etc. ahead of time.
my favorite is the knitted variety which can be thrown safely to children, used indoors, etc. Always have one in the glove box in case the situation arises.
