A user has discovered a rather nasty bug which I have verified.
The scenario it happens is, add a forwarder so email gets forwarded to a pop box. Then add the pop box to outlook and set keep emails stored on server, also tick remove after 3 days and remove when deleting locally.
Now dont delete locally and use your email normally for few days (best to try this on an active email so you get email) and you will find that email starts been delivered to outlook again and again. He told me its happening to all his email but for me its happened on just 1 email. I dont know how it works but outlook must be not detecting it already has downloaded the message so maybe its not getting a downloaded tag by the email server.
This is verified on both my DA boxes.
