As you mentioned, you have Microsoft 365, please not your subscription should be Enterprise. If you have the said subscription and you still don’t see Exchange option, please provide us with the screenshot of Microsoft 365 Product Information. To get this screenshot, open Word or Excel on your system, click File>Account, capture the screenshot of all the information mentioned under Product Information.
We will look forward to your reply. We appreciate your understanding and co-operation. Have a nice day. Stay safe and stay healthy.
Sincerely,
