Scheduling and managing events using Outlook.com calendar
Not sure if there is a difference but I'm using the free version at outlook.live.com. I mention this as settings capabilities may be different depending on what you are using. I've received 8 of these starting on 03/23 from different domains with the label "Microsoft Suggestion". Events that are going directly to my junk folder but ending up in my outlook calendar just shouldn't be happening.
Offending events have now been blocked and I'll see if future events appear in my calendar. This still wouldn't resolve new events from different domains appearing.
A definitive solution and end to this would be greatly appreciated.
