Where to manage domain for Office365 (Mail) and Wordpress/Magento
ph flag

I currently inherited a installation running its own server for hosting (Wordpress/Magento) and also e-mail. E-Mails are used within the organization via Outlook (non 365) and imap.

The plan is to switch to Office 365 (as we will also use Dynamics 365 CRM in the future) and I'd like to switch over from the self-hosted emails to using Office 365.

I am wondering now, what is the better solution.
