email server not changing in .env

[onpreme]

Hi. Didn't want to file this as an issue as I'm not sure it's not something I'm doing. I've had Snipe-it set up for a while, and finally getting around to configuring email. I've made the changed in the .env file but they just dont seem to be taking.

I've edited the .env for Office 365, but when i do a test send it's still trying to connect to email-smtp.us-west-2.amazonaws.com.

Definitely other edits to the file work (turning on debug mode), and changing my from email address and clearing the cache changes that in the send test area, but it still seems to be trying to send through amazon.

Anyone have any thoughts?
