Mysterious Exchange rule moving messages only from our domain to JUNK folder

One user is having this issue (we use a hosted Exchange 2010). It crept up suddenly a few days ago.

All messages from our domain to the user go in a folder named JUNK.  Notice this is a new folder, and not the same as junk folder which is there by default.

It seems to occur in Exchange as I have turned off Outlook on this computer and use the web access to see the message arrived in the inbox, stay there at least a full minute, then suddenly move to the other folder.

I've made sure there are no rules in Outlook.   I've selected "Do not filter junk e-mail" in the web access (even though our domain is in the safe senders list).

Any advice is welcome!

It sounds like email client is moving the messages. Are you able to make sure the users email client is not open and test again ?

Are you using any 3rd party email filtering service? If its creating its own junk folder, thats very often what a 3rd party that is integrated with Exchange would do. Or maybe ask the hosting provider what they use.

I've had this issue before, where one computer would get it and the other would not. Also, select the do not put mail in the junk folder in the Outlook client too.

As a test idea, does the user get the message on OWA but not Outlook?

I have verified that Outlook 2010 is not running on the client. At one point I created a new profile for the user account and it still happened.

There is a spam filter, but it retains the messages on their server to be delivered once released by the user.  Just in case I looked at the header for the message, don't see anything directing it to a folder.

It's interesting that it comes in to the inbox and rests there for a little while before moving.

I went into the Outlook client and junk, junk options and told it not to filter.  Again, I find it interesting that the messages are moving to a folder called Junk, whereas Outlook normally moves spam to a folder called Junk E-Mail

Is POP3 and IMAP enabled? If you can disable that to make sure any other clients aren't connecting that would be great.

If its making it to the users mailbox, then its not an Exchange rule. It has to be a 3rd party AV product with an SMTP hook into the program. Trend Micro has used a folder called Junk for years.

Yes, the message goes to the inbox and sits there for 2-3 min. before moving.

I thought it might be a/v Bitdefender cloud, but that gets its settings from the console that I run, and his profile matches everyone else's.  

The computer is a clone and I double checked that no extra software  is installed. Or antivirus/mail apps.  I disabled most of the add-ins.

All seems moot since the problem occurs when Outlook is closed on the client pc anyway.

I checked on Exchange server and IMAP and POP3 were not enabled.

I do have OWA/HTTP  MAPI  ActiveSync on.

OK, so one last remaining thing is activesync. Is the user using a smartphone? I will say there really isnt any other way that it can happen. Some outside force has to be doing this. I have never heard of any filtering via a mobile app, but who knows.. I dont scour the app stores for whats new much anymore.

Yeah, I see a Samsung device, could it be linked to Exchange and then to something like Gmail?  I'll uncheck it.

I think that's it.  The nimnod hooked up this phone and didn't tell me - I saw it on exchange setup.

Here is the listed solution if anyone else is looking... do this on the phone.  I'll try and report back if it doesn't help.  Thanks all.

Go into the E-Mail app
Press the Menu Key
Select Settings
Select General Settings
Select Spam addresses
Remove any addresses that should not be in there.
