Hi all! 

I’ve submitted an IdeaExchange idea to address an issue we face with the limitation of the SFDC case email not allowing to @mention people (similar to what we have in Outlook), unfortunatelly this is only available via post/chatter which is not an option - idea URL https://ideas.salesforce.com/s/idea/a0BHp000019OmsNMAS/enable-mention-functionality-in-the-sfdc-case-email-form-same-as-in-outlook

If you’ve faced the same issue, I’d really appreciate your vote and comments:
