Issue editing Purview Message Encryption

Jon Mercer 856 Reputation points

I don't know if I am fighting a license lever requirement since there is mention of needing an E5. I have a M365 E3, or if the documentation at is just missing something. I go through all the steps to connect to exchange online and such in PowerShell, and run Set-OMEConfiguration -Identity "Message encryption configuration" -ReadButtonText "Read Secure Message." to change what it says because a white text Read Secure Message is causing chaos for all the emails we are sending using the encryption feature, and I get this. Set-OMEConfiguration: The operation couldn't be performed because 'Message encryption configuration' couldn't be found.

Why am I getting this? We are trying to use the mail flow rule so all our PII and HIPPA emails are encrypted but if people we keep having to explain to people that they are supposed to click on the read secure message. I want to change it to say something like click here to read secure message.

    Hi @ Jon Mercer,

    I tested with an E5 license and there is only one default template by default.

    Therefore, you can create a new custom template or modify the settings in the default template to modify the branding template.

    In addition, this article mentions that a 90-day trial of the Microsoft Purview solution is available for non-E5 customers.

    Judging by the error message, you're trying to edit a non-existing template. Make sure to run Get-OMEConfiguration to get the existing templates, then pass the correct identity value for the one you need modified.
