Using Outlook email encryption with Office 365 A1

[DavR]

Is anyone successfully using the inbuilt Microsoft Outlook email encryption with an Office 365 A1 subscription? 

 

I can see various guides on enabling Microsoft Purview Message Encryption, but these all seem to rely on Azure Rights Management. From what I can find, Office 361 A1 includes a basic edition of Purview Message Encryption, but not Azure Rights Management, which Purview Message Encryption needs to function?! This seems kinda contradictory.

 

I'm pretty sure from the guides I've seen I could just enabled Azure Rights Management, but I'm just trying to stay within my current agreement. Microsoft licensing, once again, clear as mud 😂

 

Tbh it's a bit of an academic question, as we have Egress Switch for when we really want encryption. But someone said the other day that they were requested to use it by one of their contacts, so it would be good to give her a firm Yes or No.

When we were on A1 it seemed to just work with no configuration. Just set the encryption on the email (yellow padlock icon on the "Options" tab on the ribbon) to either "Do Not Forward" or "Encrypt" 

 

The only problem was opening attachments that were made with Office as those would automatically get stamped with IRM and would cause trouble with Office 2016/2021.
