Support ticket required

Question

All of the settings surrounding my email and calendar are set to prevent events from being added to my calendar without my permission, but spammers are still able to do it. I have spent many hours over the last few days trying to resolve this. I have NO option for even creating "delagates," much less deleting them. Allowing automatic acceptance of meeting requests is not checked and is greyed out, anyway, so I can't enable it if I want to. In short, every single solution offered through your support portal has not worked. This is not a global corporation. I am a single subscriber to MS 365 and am therefore the administrator. If I don't fix it, it doesn't get fixed. So please tell me how to stop spammers from adding crap to my calendar.

Answer 1

This happens when spammers send meeting invitations that bypass normal filtering.

Fix

In Outlook Web: Settings → Calendar → Events from email

Turn everything OFF

In Junk email settings:

  Block the sender
  
     Disable automatic processing
     
     In **Exchange Admin Center** (if business account):
     
        Create a **transport rule**: “If message is meeting invite AND from outside organization → quarantine.”
        

If you’re a home user, only steps 1–2 apply.
