Encrypt Emails with Microsoft 365

The Office 365 Message Encryption Protocol (OME), which is part of Microsoft 365, makes sending emails to clients and external parties safe and easy. In order to ensure the security of emails sent to recipients, users can use strong encryption regardless of which email provider they employ. OME works with most email providers ranging from giants like gmail to smaller email providers.

Users log in through a web portal using credentials or one-time passwords to access a portal where administrators define transport rules. Emails containing confidential information are delivered as HTML files. To be able to do this you do not need to have any special software installed or have a Managed IT Services Albuquerque team in place.

In addition to mailbox audit logging, enable DKIM, SPF, and DMARC . Disable automatic forwarding and the options for POP3 and IMAP4 .
