Account does not show up in "unread" favorite...

In Windows 11, I have at least one email account that never shows up in the ‘unread’ folder when a new email comes into it. I cannot find anything on that email account that disables that feature.

Anyone know of a setting that I’m missing that will make the account show up in unread folder of my ‘favorites’?

If I don’t check that account inbox directly, I never see the emails in ‘unread’. They’re in the account inbox when I go to that inbox.

Thanks.
