Message Centre Alerts - False positive and incomplete information
I had received an alert in the Message Centre 'Problem Detected: Unusual Activity by some of your users'. In this message it indicated that our subscription would be disabled for 60 days. I opened Case #:19721202 to inquire about what was going to be disabled, along with why the message did not indicate the users with the unusual activity.
As per the update from MS Support - the alert can be ignored and please log a User Voice so that this can be investigated further by the Product Engineering Team.
