Outlook rules not running

[nikwak]

Honestly pulling my hair out here. I had Outlook set up on a computer which had a hard drive crash so I put new hard drive in and after installing my Office365 I cannot get any of my Outlook rules to run - they were working perfectly on the old drive. Have tried rules on different pst files. Have done a cleanrules. Have deleted the rules and redone them. They don't even work when I try to run them manually. Have googled this and it appears many people have got this problem and are in the same boat as me. I have run OutlookTools and Stellar Repair for Outlook - nothing helps. Can someone come up with the answer? Microsoft don't seem to have one.
