Purview Message Encryption - Broken Icon
The lock image url referenced in the "has sent you a protected message" email is invalid. Image source: https://outlook.office365.com/Encryption/lock.png I can confirm this was last working on 2/12/2025. Messages sent on 2/12 and today 3/6 reference the same url. This is not a case of the image being blocked by the mail client. Thank you, Matt

Can Exchange Online Protection check for TLS before forcing encryption
I know this is possible in Iron Port but not sure if EOP can handle this scenario, so asking for others opinions. In Iron Port, you can setup rules to say "If this email contains DLP data, check for TLS delivery. If email is being sent with TLS -> do not force message encryption. If email is not being sent with TLS -> Force message encryption." Can EOP execute similar functionality. Essentially what I am looking for is whether not EOP is smart enough to only use OME when TLS is not available.
