I have access to Inboxes but cannot see any Inboxes. Why?

Access to Inboxes is based on ownership and membership.

Only the inbox Owner and Administrators can add other members as Owners, Writers, or Readers.

If you have not been added as a member to an inbox, you will not see any inboxes on the inbox overview page.
