I've been having problems with my email server (We´re using Office 365). I've found that odoo is not compatible with Odoo online, but with Odoo on-premise. Sincerely, I have no idea what's that, I've searched and there's Odoo.sh, Odoo on-premise, Odoo online... I don't know their differences and even which one we have.
The only thing I know is that I have Odoo 12.0+e Enterprise
Help please :c
