All of my AOL mailboxes are grayed out in Mac Mail

My AOL favorite mailboxes in macmail are grayed out except for inbox. I am not able to get to the following mailboxes:

Sent

Drafts

Junk

Trash.

This happened after I uninstalled AOL mail and reinstalled it again.

How can I get them back again.
