I have an unusual situation where a meeting invitation is getting blasted out by a bunch of people.
To try and explain, I work for a school district and we have a distribution list for just the district office staff. The invitation to this meeting was sent out originally by the superintendent's assistant for October 11, 2013 to the district office staff distribution list.
Now what's happening is several other accounts have been sending that same invitation but then immediately after receiving the invitation, I receive up to 14 meeting cancellations (for that same meeting). One of the people the invitation came from is a teacher and not even on the district office DL.
Another strange thing is when I receive the meeting invitation it states the meeting is in the past but how can a meeting in October of this year be in the past?
I've scanned our email servers with a Malware program and one malicious item was found on both email nodes. That has been cleaned.
I've scanned with MS Forefront (not Forefront for Exchange) I don't know how effective that is since it's set to not scan the exchange databases - the scan found nothing.
Has anyone else experienced anything like this? Does anyone have any tips or ideas of things to do?
