Using Classic Outlook on Windows for personal email, calendar, and contact management
Dear jaiPHCP,
Greeting. Thank you for posting to Microsoft Community.
Based on your description, I understand your query is about “Identification in a shared mailbox”. We did thorough research and testing from our side. However, it seems that there are no features that can fulfill your needs.
For the feature you proposed, please forgive me for taking the liberty of raising a new piece of feedback for you on Community (microsoft.com), which is Microsoft's webpage dedicated to collecting customer feedback on products. I will invite my team to vote on it, and users who want the same will join the vote and comment when they see it, so that it will appear at the top of the page, which makes it easier to quickly submit feedback to the product group. Your suggestions help us to provide better service to you and other users. We highly value each customer's feedback on our products.

Hopefully this will be included in future product updates.
Your understanding and cooperation are greatly appreciated, and if there is anything else that can be done for you, please feel free to reply.
Have a good day.
