Office 365 message encryption

[Guest Guest]

We've being having issues with Birmingham city council in that we are unable to open encrypted attachments sent by them and vice versa. This is a known issue which they've made no progress on

 

Someone from BCC has told us that "as the emails are encrypted with TLS there is no need to encrypt"

 

This isn't right surely?

Depends, what's the attack scenario?

 

a) someone listening on the line, TLS fixes that

b) someone with the email account password? OME doesn't fix that.
