Question Issue with new version of Outlook ?

[Grizzly_2024]

We have a user on Windows 10 who attempted to switch to the new version of Outlook. Once they do that, they cannot connect to the shared mailboxes and requesting the user to sign in to the shared mailboxes. Has anyone seen this before and how to resolve?

is this user in the same local network?
