Emails marked as spam from a user in my domain to a user in my domain

Valid Emails are being marked as spam and going to the junk folder.
The emails are from a user in my domain to a user in my domain.
We are running Exchange 2013 but still have our legacy 2007 exchange server that we are using for public folders until I finish the conversion.
Any suggestions on what setting I have missed or need to set?

Hi,
Exchange will never deliver its own domain email to junk folder.
You maybe having antispam in between.  Please check if you have any antispam in play.

Thanks

check the headers to make sure that it is not a spoofed email

No these are actual emails that the staff are sending to each other.  But they were not receiving them until they looked in the junk folder and there they were.  This has become worse over the last few days.

I have the exchange 2013 malware filter turned on but I don't think it could be that.  We have Avast antivirus on our clients but they claim they don't send that type of message.
if they are genuine internal emails, then it sounds like something in Outlook that is causing this.

have you checked the junk options ?

although it is difficult to prove a negative, you could as a test get one user to completely close down Outlook and work in OWA instead and see if any emails go into junk, if they do not, then it would further point to it being something in Outlook.

I have check the junk mail options and they set to no automatic filtering.  I have turned off the "Mail Shield" on our Avast security software.  I am still getting emails from internal uers going to the Junk email folder marked as  *** SPAM ***

Below is the Header information - it has a SCL: -1 but what does the "X-Antispam: spam, score=90" mean?

*** SPAM ***  seems not native in Exchange.
You might have a local AV install and attached to Outlook

Turned off Avast's mailshield and that seems to have worked.

Thank you!
