AnswerGFI MailEssentials is configured to move mails blocked as SPAM to a subfolder of the users’ mailbox. Users who are connecting to Microsoft Exchange via POP3 are not able to view the mails blocked as SPAM.
In such instances, users will need to connect to Microsoft Exchange using IMAP rather then POP3. This will enable the users to view not only the mails in their Inbox, but to view also mails in the Inbox subfolders, thus allowing the users to view the mails which are blocked as SPAM.
IMAP stores email on the server and therefore allows you to view the mailbox, versus POP3, which will create local copies of emails on the dedicated machine and will delete the mail from the server.
