Email encryption with office 365 and azure

Hi All,

I'm trying to setup office 365 Email encryption and having some issues. Following these instructions:

http://office365support.ca/setup-and-enable-office-365-message-encryption/

This command:

Set-IRMConfiguration -RMSOnlineKeySharingLocation https://sp-rms.na.aadrm.com/TenantManagement/ServicePartner.svc

Gives this error:

The Trusted Publishing Domain (TPD) for your organization should be managed in Microsoft Azure Rights Management. The 'RMSOnlineKeySharingLocation' parameter has been deprecated. For more information, see http://go.microsoft.com/fwlink/p/?LinkId=789272.

+ PSComputerName : outlook.office365.com

I've also tried folowing these instructions:

https://support.office.com/en-us/article/set-up-new-office-365-message-encryption-capabilities-built-on-top-of-azure-information-protection-7ff0c040-b25c-4378-9904-b1b50210d00e

and completed the comands with no error, but when I send an encrypted email and try to open it in the web browser I get this error every time:

Sorry, we can't display your message right now

Something went wrong and your encrypted message couldn't be opened. Please try again by following the instructions in the original email message in 5 minutes.

Any help would be appreciated
