Contents of spam folder for additional Mailboxes not showing
When multiple emails are added via mailboxes, whichever account is not active will not show all of the contents in the spam folder.
For example- I am logged into email #1 and add email #2 as a mailbox. The active account is email #1. I go to view the spam folder for email #2 and nothing is there. I set the active account to email #2 and view the spam folder. There are emails there.
