Hosted Exchange Account has 2 Junk Email Folders, "Junk" and "Junk E-mail"

I have an Exchange 2010 email account with 3 mailboxes hosted by Network Solutions. Outlook 2010 is installed on the clients. Outlook shows two folders ("Junk" and "Junk E-mail) for junk email. Some good email is getting sent to the "Junk" folder. I already disabled the Outlook spam filter (it was sending spam to the "Junk E-mail" folder). In addition, the hosted exchange account includes MessageLabs (Symantec) off-site spam filtering which sends an email notifying the user whenever spam email is detected, but doesn't move spam to any folder. I don't have any rules set up.

My main question is this:
What program is identifying good emails as spam, and sending it to the "Junk" folder.

Merry Christmas

Very good possibility the "Junk" folder is from another Outlook add-in or external application that scans your email like AV, etc. The "Junk Email" folder would be the Exchange default naming.

Do you have any firewall rule may be that is causing the issue like for me I am using FOPE where I have seen lots of times emails are going into spam folder after allowing the domain into safe list emails are going into Inbox .

Can you open the original email from junk folder only go for the message tracking hope you will get the answer from there, Why the emails are going into a spam folder

Did you get the chance to look antivirus rules and policies.

/ResetFolderNames will not do anything unless in some way the original folder got renamed. This is typically used when moving a Outlook client between languages. Example if wanting a Spanish language install to now be English, this switch will set the default folder names to the current referenced language configured.

I don't have any firewall rules that would affect junk email. My antivirus program does not have any anti-spam tools. I disabled the default Microsoft spam filter, even though it puts spam into a different folder (Junk Email). Many good emails from long time vendors continue to go to the "Junk" folder. Message tracking does not point to the cause. I attached the msg header of an affected email. header.txt

Your mail server is using Trend Micro to scan email and is probably why this is happening.
