While we can send email via a SMTP connection to a regular Office365 mailbox,
Microsoft places limits on the delivery speed and maximum messages per day. An alternative
is to configure Office365 SMTP Relay which will ensure your mail client does not limit or block
emails sent from Litmos. The majority of this work will need to be conducted by whoever has
full admin access to your organization’s account, such as your Mail and/or DNS Administrator,
as they will need to sign into https://admin.microsoft.com/AdminPortal.
