Encryption in Exchange Online Part 7

In the first six parts of this series (Part 1, Part 2, Part 3, Part 4, Part 5, Part 6), I’ve covered the basics of  encryption, BitLocker, TLS, Office 365 Message Encryption, Information Rights Management, and S/MIME.  In part seven, I’m going to wrap the discussion of encryption within Exchange Online by providing a quick summary of each option and giving some examples of the best circumstances in which to use each.
