I don't know if this will help you, but I found a rule that directs all of those to the junk folder, but I have specified in the rule to permanently delete them but it doesn't work. it is so frustrating and really ticks me off, I'm tired of the bs. Apply this rule after the message arrives to where my name is not in the To box and with "preview or new or info or office or medhireuniversity in the senders address and permanently delete it. except where my name is in the to box stop processing more rules. I have the enable rules on all messages downloaded from RSS feeds checked.
I also have a problem with an email getting permanently deleted that i want. So I marked the sender as safe, but it still gets permanently deleted every date. These reply messages from microsoft also end up permanently deleted.
The rule would work, if it worked. LOL I'm no expert on outlook, so if anyone can find my error with the rule please let me know, otherwise I'm going to abandon this email and start over.
