Specify IP address ranges: (You must click the plus sign after each entry)

Do the following: Should already be set to "Set the spam confidence level (SCL) to..." > Bypass spam filtering (If the value isn't already set for some reason select Modify the message properties > set the spam confidence level (SCL) > select Bypass Spam Filtering > click OK) 

Choose a mode for this rule: Enforce

Comments: This rule must remain in place to allow AES traffic to bypass Office 365 filtering.
