Hundreds of fake calender entries being created due to an Outlook.com exchange server issue

Question

I need to contact Outlook.com support to fix the following issue diagnosed by New Outlook app support

Hello, Thank you for the detailed updates and your patience. Based on everything you have confirmed, this issue is not caused by Outlook settings or your computer. The calendar events are being created automatically at the server level, which is why they continue to appear across New Outlook, Classic Outlook, eM Client, and Outlook.com (web), even when you are not logged in. You have already completed all the correct steps: ⮞Events from email are turned off ⮞No unknown rules or shared calendars exist ⮞The issue continues across multiple devices and apps The fact that: ⮞Hundreds of events are being created daily ⮞Events arrive in rapid bursts (every few seconds) ⮞The source appears as your own account via an Exchange server strongly indicates a corrupted calendar process or a backend synchronization issue within your mailbox. ⮞After reviewing our resources and conducting the diagnostic, I would like to inform you that, as you mentioned, the issue persists on Outlook on the web as well. As you may know, Outlook is merely a client that mirrors the server. For Outlook to function properly, the issue must be resolved first from the server's side ⮞Hence, I request you to reach out to our Outlook.com support team, as the issue has to been fixed on the server end. I would love to assist you on this, but the issue is related to the server end, and we do not have the resources to make changes or have permissions on the server end. Please contact Outlook.com Support using the link below.
