Excellent article. &nbsp;Thank you.

We have an on prem Exchange 2013 server and our only smart host is our Office 365 account. &nbsp;So, our email server sends mail to O365 to be sent on to the recipient.<br />
<br />
We need to force TLS to one of our recipients. &nbsp;I went in to build a connector to do that with. &nbsp;Another tech of ours says, hey, we have a transport rule. &nbsp;Just add the domain to the transport rule.<br />
<br />
That got me to thinking, what's the diff in using a transport rule vs using a connector to force TLS? &nbsp;Can someone explain that to me?<br />
<br />
Thanks<br />

Force TLS - Connector vs Transport Rule

Office 365 is a group of software plus services subscriptions that provides productivity software and related services to its subscribers. Office 365 allows the use of Microsoft Office apps on Windows and OS X, provides storage space on Microsoft's cloud storage service OneDrive, and grants 60 Skype minutes per month. Office 365 includes e-mail and social networking services through hosted versions of Exchange Server, Skype for Business Server, SharePoint and Office Online, integration with Yammer, as well as access to the Office software. All of Office 365's components can be managed and configured through an online portal; users can be added manually, imported from a CSV file, or Office 365 can be set up for single sign-on with a local Active Directory using Active Directory Federation Services.
