Exchange 2010 and Outlook Junk E-Mail

I have an Exchange 2010 sever and a few corporate domains. All the domains are in the Accepted Domains list and all our subnets have been added to the IP Allow List in the Anti-Spam tab of the Hub Transport server under server configuration.

Now for some reason when one of our other servers uses an smpt connector to send mail, an alert for example, the message will show up in our Outlook Junk E-Mail instead of our Inboxes.

This is a work around. Add that domain as safe sender.

Here is the best logic for emails landing up in junk folder from Microsoft

Now here is where the confusion begins. The server side filter that Exchange store uses to deliver messages to junk mail has two parts. There is the setting on the mailbox and/or OrganizationConfig object to determine at what SCL value we decide to send a message to the junk e-mail folder. However, for the spam to actually be moved to the junk e-mail folder, a hidden inbox rule has to be enabled. This rule can be enabled in a number of ways. One way is to log into your inbox with Outlook in cached mode. Another is to turn on junk mail filtering in Outlook Web Access (by going to Options and then Junk E-Mail).

Now if you weren't confused already here is the super confusing part- Enabling the rule with the Outlook cached mode way also enables Outlook's client side filtering as well. Turning it on in OWA but not in Outlook (either never logging in with Outlook or going to Tools, Options, Junk E-Mail Options, and clicking the "No Automatic Filtering" radio button in the Outlook client) only turns on the server side Exchange filtering.

Hence, turn off Automatic filtering in OL AND junk email option in OWA.

FYI, I only have a Hub Transport and no Edge Transport.

Is there a way to view the hidden Inbox rule or tell if it is enabled?

And what is the best way to view the SCL settings?

As I understand it the SCL rating is 0-9 where the lower the SCL, the less likely that the message is spam. Also, messages with an SCL rating of 6 or above are suspicious and should be treated with caution. Please correct me if this is wrong.

I re-wrote the solution to read better. I have had a chance to test this solution and it is right-on. Thanks again for your help.

Here is the best logic for emails landing up in junk folder from Microsoft:

The server side filter that Exchange store uses to deliver messages to junk mail has two parts. There is the setting on the mailbox and/or Organization Configuration object to determine at what SCL value we decide to send a message to the junk e-mail folder. However, for spam to actually be moved to the junk e-mail folder, a hidden inbox rule has to be enabled. This rule can be enabled in a number of ways. One way is to log into your inbox with Outlook in cached mode. Another is to turn on junk mail filtering in Outlook Web Access (by going to Options and then Junk E-Mail). Now, Enabling the rule with the Outlook cached mode way also enables Outlook's client side filtering as well, turning it on in OWA but not in Outlook. So either never logging in with Outlook will keep it from being enabled or going to Tools, Options, Junk E-Mail Options, and clicking the "No Automatic Filtering" radio button in the Outlook client will disable it manually.

Special note: Even if you don’t use Outlook Web Access, as noted above it can be tuned on Automatically by opening Outlook in cached mode. So it's important to go into OWA and change the "Block or Allow" settings to "Don't move e-mail to my Junk E-Mail folder.
