Hello,
We have Office 365 E3 subscriptions, and we would like to customize the Welcome email for Outlook 365, so users would have enough information about company business.
I would like to know, if we can achieve this with some existing tools in Exchange 365, or we need to use other Office 365 services, like Flow, or Power Automate, or we need to use some third party solutions, since we are aiming to send some old emails that are meant to be distributed for all users, including the new arrivals.
Thank you in advance,
