Outlook synching issue, emails being repeatedly received

Two days ago I started re-receiving emails that have been sent to me in the last 2-3 weeks (these are from multiple sources).  I spent several hours with Microsoft support and we confirmed it was an outlook web synching issue, took a series of steps (signing out of all devices etc) and I was told that it would resolve itself in 24 hours and all these additional emails would be deleted.  We are now 40 hours later and I am still receiving these emails again and again and now have 130,000 messages in my inbox (I had 3,000 on Wednesday).  I have just been on with Microsoft support again, they said it needs escalating but no one is available (again) and to contact back in 4-5 hours. This is taking hours of my time and I am not getting anywhere and so wondered if this community might be able to help me.  Thank you.

    Outlook has a syncing loop problem that causes a significant amount of inbox duplication by repeatedly re-delivering previously received emails.

  • Is this an outlook.com or a business Exchange account? You can create a rule that deletes these and do a permanent delete in the rule. For my business account, I set up a rule/policy that blocks them from coming in at all.
