I was able to reproduce the issue at my end once I have created a new user in my Active Directory account that doesn't have the mailbox for that user. When I logged in with this user credentials I can see the same behaviour at my end.

Please verify whether the user that you have login in has a mailbox created and has required permission. You can reach out to your team/admin to confirm the same.
