I have a rule for Outlook to move messages from a specific sender to a specific folder. What I'm seeing instead is that all new messages from random senders are being sent to the specified folder. I attempted to run the rule on messages which were in my inbox previously, and in this case the rule worked as expected, so it seems to only be new messages that are being sent to the folder wrongly. Is there something I'm not understanding about the way rules are applied?
This is the only rule I have setup in Outlook. Here's the rule's description:
Apply this rule after the message arrives from email@example.com move it to the Specified folder and stop processing more rules
Another note, as I'm unsure if this is relevant or not, but the sender address I specify is an automated sender.
EDIT: After Further Investigation: I've determined that if a user is 'flagged' by this rule to be sent to the specified folder, messages from that user will always be sent to that folder.
EDIT: I attempted to set a rule to intercept senders that were being sent incorrectly, by targeting their emails specifically and disallowing further rule execution, but this then prevented the email I actually wanted to be moved from being moved. It seems that somehow several emails are being identified as from the same sender though their address are different.
