Authentication Errors

I'm having a heck of a time getting MBMPro to send any emails. I keep getting 5.7.8 errors trying to log into gmail, yahoo, Office365, etc. I've copied the Delivery log for one of these attempts below. (It shouldn't be this hard!)

I'm running a Retina MacBookPro, 15", Late 2013, 2 GHz Intel Core i7, 16GB RAM, OS X 10.13.2 and MBMPro 8.6.6.

Thanks!

Interestingly, the send worked when I used my work computer (Mac Pro, Early 2009, 2.66 GHz Quad-Core Intel Xeon, 20 GB of 1066 MHz DDR3, OS X 10.11.6) and not my home computer (Retina MacBookPro, 15", Late 2013, 2 GHz Intel Core i7, 16GB RAM, OS X 10.13.2), and the following settings:

MBM Pro 8.6.6
smtp.office365.com:587
TLS v1 Exp
ESMTP (Login)
10.44.119.35 (my computer's ip address)

Could the problem lie with my ISP, Spectrum?

I just tried WITHOUT the :587 and it worked, but I had tried this before as well when it didn't work. Do you think it could be my network? This time I tried the send at 20:30 so network traffic probably was lower. I had tried to send previously during the regular workday.

I also just tried WITH :587 and it also worked.

Ideas to figure this out?
